A dataset for computer-vision-based fig fruit detection in the wild with benchmarking you only look once model detector

The image datasets that are most widely used for training deep learning models are specifically developed for applications. This study introduces a novel dataset aimed at augmenting the existing data for the identification of figs in their natural habitats, specifically in the wilderness. In the present study, researchers have generated numerous image datasets specifically for object detection focus on applications in agriculture. Regrettably, it is exceedingly difficult for us to obtain a specialized dataset specifically designed for detecting figs. To tackle this issue, a grand total of 462 photographs of fig fruits were gathered. The augmentation technique was utilized to substantially increase the size of the dataset. Ultimately, we conduct an examination of the dataset by doing a baseline performance study for bounding-box detection using established object detection methods, specifically you only look once (YOLO) version 3 and YOLOv4. The performance obtained on the test photos of our dataset is satisfactory. For farmers, the capacity to identify and oversee fig fruits in their natural or developed environments can be highly advantageous. The detecting device offers instantaneous data regarding the quantity of mature figs, facilitating decision-making procedures.

Ecological perspectives on water quality and zooplankton diversity in the Ravi River

AbstractFreshwater ecosystems are intricately linked to the diversity and abundance of zooplankton assemblages, which serve as vital indicators of environmental conditions. The aim of the present study was to investigate the habitat ecology in relation to zooplankton abundance of the Ravi River. Sampling was conducted at selected sampling sites along the Ravi River basin, encompassing various habitat types and environmental gradients. A total of 13 species of zooplankton were observed during the study in which Copepoda was most dominant followed by Cladocera. Cyclops sp. (152 ind/L) and Bosmina sp. (145 ind/L) were the dominant genera throughout the study. Asplanchana sp. (44 ind/L) was observed as a rare species during the study. Some habitat ecological parameters like water temperature, dissolved oxygen, and total dissolved solids show a declining trend in Zone 3. Turbidity was highest in Zone 3 and lowest in Zone 1, and almost all zooplankton genera showed a declining trend in Zone 3. Dissolved oxygen shows a significant positive correlation and directly influences the distribution of zooplankton assemblage structure. This study concludes that certain anthropogenic activities like municipal dumping, sand mining, and altered water flow have negatively impacted water quality and zooplankton diversity in the Ravi River. So, these types of activities should be monitored regularly and controlled immediately.

Seasonal migration patterns of Siberian Rubythroat (Calliope calliope) facing the Qinghai–Tibet Plateau

BackgroundSmall songbirds respond and adapt to various geographical barriers during their annual migration. Global flyways reveal the diverse migration strategies in response to different geographical barriers, among which are high-elevation plateaus. However, few studies have been focused on the largest and highest plateau in the world, the Qinghai–Tibet Plateau (QTP) which poses a significant barrier to migratory passerines. The present study explored the annual migration routes and strategies of a population of Siberian Rubythroats (Calliope calliope) that breed on the north-eastern edge of the QTP.MethodsOver the period from 2021 to 2023, we applied light-level geolocators (13 deployed, seven recollected), archival GPS tags (45 deployed, 17 recollected), and CAnMove multi-sensor loggers (with barometer, accelerometer, thermometer, and light sensor, 20 deployed, six recollected) to adult males from the breeding population of Siberian Rubythroat on the QTP. Here we describe the migratory routes and phenology extracted or inferred from the GPS and multi-sensor logger data, and used a combination of accelerometric and barometric data to describe the elevational migration pattern, flight altitude, and flight duration. All light-level geolocators failed to collect suitable data.ResultsBoth GPS locations and positions derived from pressure-based inference revealed that during autumn, the migration route detoured from the bee-line between breeding and wintering grounds, leading to a gradual elevational decrease. The spring route was more direct, with more flights over mountainous areas in western China. This different migration route during spring probably reflects a strategy for faster migration, which corresponds with more frequent long nocturnal migration flights and shorter stopovers during spring migration than in autumn. The average flight altitude (1856 ± 781 m above sea level) was correlated with ground elevation but did not differ between the seasons.ConclusionsOur finding indicates strong, season-dependent impact of the Qinghai–Tibet Plateau on shaping passerine migration strategies. We hereby call for more attention to the unexplored central-China flyway to extend our knowledge on the environment-migration interaction among small passerines.

How loss of nature through clear-cutting forestry affects well-being.

The United Nations declares that the global degradation of ecosystems represents a danger to human health. Deterioration of forests is one of several threats against the natural systems. The aim of this exploratory study was to investigate people's experiences with clear-cutting and how it had affected their health and well-being. Qualitative data from six people who valued forest ecosystems were collected through semi-structured interviews and analyzed in accordance with Graneheim and Lundman's qualitative content analysis (Graneheim, U. H. and Lundman, B. (2004) Qualitative content analysis in nursing research: concepts, procedures and measures to achieve trustworthiness. Nurse Education Today, 24, 105-112). Clear-cutting was not regarded as an environment-friendly forestry method. The interviewees described emotional reactions such as grief and poor mental well-being when beloved forests were clear-felled. The grief was partly because of a personal loss of place and recreation area that was important for their physical and emotional well-being. Another part was grief on behalf of nature itself, that is, the loss of habitats of animals and plants and a worsening of the global climate. The interviewees held that emotions related to loss of nature were insufficiently communicated in public discourse. They felt powerless and unable to influence forestry because of what they experienced as an impenetrable industry. Clear-cutting of forests may result in poor well-being among people who value forest ecosystems. More focus on planetary health is needed, including healthy public policy promoting forest management that considers people's need for nature experiences and possible ecological grief when forests are totally and abruptly cleared.

Bird Habitat Suitability Analysis of The New City Centre Gede Bage Bandung Using Landscape Metrics

Abstract One focus of landscape ecology studies is the study of landscape patterns. Understanding the landscape patterns can help to find suitable habitat for the development or restoration of wildlife habitats, which can partly be expressed quantitatively with measurable or computable indicators by Geographic Information System, i.e. landscape metrics. This paper aims to analyze suitable habitat for bird habitat in The New City Centre in Gede Bage Bandung using statistical relationships between the occurrence of birds and the landscape pattern. Our study focus on habitat for Javan Pond Heron (A. speciosa) and Cattle Egret (B. ibis), two bird species which has been lived since 1970 in Ranca Bayawak Village inside The New City Centre Gede Bage Bandung. This study using landscape metrics software FRAGSTAT 4.2, parameter characterising landscape pattern were determined for the UTM 4 km x 4 km cells covering the whole of The New City Centre Gede Bage Bandung. The characteristic bird habitat define based on three types of landscape pattern : built-up areas, green spaces and water bodies. The study results based on statistical calculations found green spaces landscape metrics especially paddy field, forest and green open spaces are suitable for bird habitat, the type of patch that has the second largest patch size from total area. From statistical calculations also known built-up areas landscape metrics has the highest probability of fragmentation and the highest edge effect as a result of The New City Centre Gede Bage Bandung development.

Using multiple scales of movement to highlight risk–reward strategies of coyotes (Canis latrans) in mixed‐use landscapes

AbstractMany wildlife species vary habitat selection across space, time, and behavior to maximize rewards and minimize risk. Multi‐scale research approaches that identify variation in wildlife habitat selection can highlight not only habitat preferences and risk tolerance but also movement strategies that afford coexistence or cause conflict with humans. Here, we examined how anthropogenic and natural features influenced coyote (Canis latrans) habitat selection in a mixed‐use, agricultural landscape in Mendocino County, California, USA. We used resource selection functions and hidden Markov models to test whether coyote selection for anthropogenic and natural features varied by time of day or by behavioral state (resting, foraging, and traveling). We found that coyotes avoided development, but, contrary to our expectations, coyotes selected for roads, agriculture, and areas with risk of human encounter and rifle use regardless of diel period or behavioral state. While traveling, coyotes increased selection for roads and avoided ruggedness, indicating that unpaved roads may enhance connectivity for coyotes in mixed‐use landscapes. Finally, we found that coyotes selected for mountain lion habitat when resting and at night, signifying that risk from natural predators was not a factor in habitat selection at coarse scales. Coyote habitat selection for places and times associated with human activity, without variation across scales, signals a potential for conflict if coyotes are perceived by people as a nuisance.

Global evaluation of current and future threats to drylands and their vertebrate biodiversity.

Drylands are often overlooked in broad conservation frameworks and development priorities and face increasing threats from human activities. Here we evaluated the formal degree of protection of global drylands, their land vertebrate biodiversity and current threats, and projected human-induced land-use changes to drylands under different future climate change and socioeconomic scenarios. Overall, drylands have lower protected-area coverage (12%) compared to non-drylands (21%). Consequently, most dryland vertebrates including many endemic and narrow-ranging species are inadequately protected (0-2% range coverage). Dryland vertebrates are threatened by varied anthropogenic factors-including agricultural and infrastructure development (that is, artificial structures, surfaces, roads and industrial sites). Alarmingly, by 2100 drylands are projected to experience some degree of land conversion in 95-100% of their current natural habitat due to urban, agricultural and alternative energy expansion. This loss of undisturbed dryland regions is expected across different socioeconomic pathways, even under optimistic scenarios characterized by progressive climate policies and moderate socioeconomic trends.

Unravelling arthropod movement in natural landscapes: Small-scale effects of body size and weather conditions.

Arthropod movement has been noticeably understudied compared to vertebrates. A crucial knowledge gap pertains to the factors influencing arthropod movement at habitat boundaries, which has direct implications for population dynamics and gene flow. While larger arthropod species generally achieve greater dispersal distances and large-scale movements are affected by weather conditions, the applicability of these relationships at a local scale remains uncertain. Existing studies on this subject are not only scarce but often limited to a few species or laboratory conditions. To address this knowledge gap, we conducted a field study in two nature reserves in Belgium, focusing on both flying and cursorial (non-flying) arthropods. Over 200 different arthropod species were captured and released within a circular setup placed in a resource-poor environment, allowing quantification of movement speed and direction. By analysing the relationship between these movement variables and morphological (body size) as well as environmental factors (temperature and wind), we aimed to gain insights into the mechanisms driving arthropod movement at natural habitat boundaries. For flying species, movement speed was positively correlated with both body size and tailwind speed. In contrast, movement speed of cursorial individuals was solely positively related with temperature. Notably, movement direction was biased towards the vegetated areas where the arthropods were originally caught, suggesting an internal drive to move towards suitable habitat. This tendency was particularly strong in larger flying individuals and under tailwind conditions. Furthermore, both flying and cursorial taxa were hindered from moving towards the habitat by strong upwind. In conclusion, movement speed and direction at patch boundaries are dependent on body size and prevailing weather conditions, and reflect an active decision-making process.

Visitation patterns of endangered grey parrots (Psittacus erithacus) in a forest clearing in the Democratic Republic of the Congo.

The grey parrot (Psittacus erithacus), once abundant, has become increasingly threatened due to the combined effects of capture for the global pet trade and habitat loss. Although grey parrots are well studied in captivity, effective conservation efforts require a better understanding of their ecological requirements in the wild. The aim of this paper is to quantify grey parrot behaviours across the annual cycle. To do that, we studied groups of grey parrots gathering in a natural forest clearing in the Nkuba Conservation Area, eastern Democratic Republic of the Congo. Using parrot counts and focal sampling, combined with descriptive statistics, we found that an average of 40 grey parrots visited the clearing each day, following a regular pattern in which they first perched in the trees surrounding the clearing, vocalizing loudly, until the group landed in the clearing to feed, drink and interact with each other. Generalized linear models (GLMs) and generalized additive models (GAMs) showed that the time at which parrots arrived, landed at, and left clearings was influenced by the weather, seasonality and the month of the year. We also found that parrots shortened their visits when disturbed by predators or the presence of humans. Although the underlying mechanisms for grey parrot visits to forest clearings remains unclear, the consistency of this behaviour observed elsewhere in Africa and the feeding observed in the clearing in this study suggest that these area support important foraging habitat for the wild grey parrots. Therefore, ensuring the availability of such clearings is paramount to the long-term survival of the species. We suggest that future efforts to protect grey parrots in their native habitats focus on identifying clearings visited by parrots, monitoring these clearings and allowing parrots to visit them without disturbance or risk of capture.

Internet of Things (IoT) for Environmental Monitoring

Purpose: The general objective of this study was to explore the Internet of Things for environmental monitoring. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to the Internet of Things for environmental monitoring. Preliminary empirical review revealed that IoT technologies have significantly enhanced environmental management practices by revolutionizing data collection and analysis across various ecosystems. By integrating IoT sensors with existing monitoring frameworks, real-time data on air and water quality, agriculture, wildlife habitats, and urban green spaces was efficiently gathered. This data facilitated proactive decision-making, early detection of environmental risks, and evidence-based policy formulation to address climate change, biodiversity conservation, and sustainable resource management challenges. Despite challenges like data security and interoperability, collaborative efforts among stakeholders paved the way for more effective environmental monitoring and sustainable development initiatives globally. Unique Contribution to Theory, Practice and Policy: The Complex Adaptive Systems Theory, Diffusion of Innovations Theory and Resource Dependence Theory may be used to anchor future studies on the Internet of Things technology. The study provided several recommendations that contributed significantly to theory, practice, and policy in environmental management. The study emphasized interdisciplinary approaches to enhance theoretical frameworks, advocating for advanced models and algorithms integrating IoT with environmental science and data analytics. In practice, it recommended widespread adoption of IoT-enabled sensor networks with enhanced capabilities for precise and reliable data collection. Policy-wise, the study called for regulatory frameworks supporting IoT integration, data standards, and international cooperation to address global environmental challenges collaboratively. Capacity building and continuous research and development were also highlighted to optimize IoT technologies for sustainable environmental monitoring and management globally.

Role of Carbon, Nitrogen, Phosphate and Sulfur Metabolism in Secondary Metabolism Precursor Supply in Streptomyces spp.

The natural soil environment of Streptomyces is characterized by variations in the availability of nitrogen, carbon, phosphate and sulfur, leading to complex primary and secondary metabolisms. Their remarkable ability to adapt to fluctuating nutrient conditions is possible through the utilization of a large amount of substrates by diverse intracellular and extracellular enzymes. Thus, Streptomyces fulfill an important ecological role in soil environments, metabolizing the remains of other organisms. In order to survive under changing conditions in their natural habitats, they have the possibility to fall back on specialized enzymes to utilize diverse nutrients and supply compounds from primary metabolism as precursors for secondary metabolite production. We aimed to summarize the knowledge on the C-, N-, P- and S-metabolisms in the genus Streptomyces as a source of building blocks for the production of antibiotics and other relevant compounds.

О расчете приемной емкости северо-западной части Каспийского моря в интересах искусственного воспроизводства водных биоресурсов в Волжско-Каспийском рыбохозяйственном бассейне

After release into the natural habitat, juveniles of semi-passable and passable fish, raised in sturgeon hatcheries and spawning farms of the Astrakhan region, do not stay in the river and roll into the sea. The main food objects for it are organisms of the “soft” benthos – crustaceans, worms and insect larvae. According to the results of research in 2020-2023, data from the analysis of the feed base during the period of the most intense food competition showed that the biomass of benthic invertebrates in the western part of the Caspian Sea is 121.1 thousand tons, production is 484.5 thousand tons. Taking into account the diets, age composition and abundance of each species of fish living in the water area of the settlement of factory juveniles, the volume of withdrawal of forage organisms is determined. livestock. The main consumers of “soft” benthos are representatives of cyprinid, atherine and goby fish species, which makes them the main food competitors of the produced juveniles. The reserve of “soft” benthos products is distributed among the factory juveniles according to the weight and daily diet of each species during the feeding period at sea. When calculating the permissible volume of release of each of the artificially reproducible water bodies, the coefficients of the maximum possible use of the feed base by juvenile fish and an increase in its number, taking into account death during adaptation to the natural environment, are used. Based on the calculations carried out, it is shown that the potential of the forage base of the western part of the Northern Caspian Sea is not a limiting factor in the stocking of the marine area with objects of artificial reproduction. The above method of calculating the receiving capacity is used in the preparation of an annual plan of measures for the artificial reproduction of aquatic biological resources.

A ecological study of galamsey activities in Ghana and their physiological toxicity

Background: Small-Scale Small-Scale Gold Mining (ASGM), locally known as "galamsey," has emerged as a pervasive issue in Ghana characterized with environmental degradation, land and water resource depletion, health hazards for miners, social and economic impacts. This comprehensive review explores the ecological and health effects of galamsey operations across different regions of the country. Methods: The study employs a systematic analysis method to examine the available literature from 2000 to 2023. Various academic databases, including PubMed, Google Scholar, JSTOR, and relevant government publications, were searched to gather relevant information. Findings: The review reveals that galamsey has had significant ecological consequences, including deforestation, habitat destruction, water pollution, and soil degradation, which have adversely affected Ghana's natural beauty. These environmental challenges pose a threat to local ecosystems and resources, particularly in the Ashanti, Western, and Central regions of Ghana. Moreover, the study highlights the physiological health issues faced by galamsey miners, such as accidents, physical strain, mental strain, kidney problems, respiratory disorders, and metabolic diseases. The presence of elevated levels of mercury, cyanide, arsenic, and cadmium in both the environment and the human body are directly linked to ASGM in Ghana. About seventy percent (70%) of the houses in ASGM community relied on surface water, and all of the homes utilized the fields or bush as their main toilet. Conclusion: Implementing remote sensing, geospatial technologies, promoting clean mining technologies, integrating environmental conservation, occupational safety and public health awareness are key technical and innovative measures to mitigate galamsey in Ghana. Novelty/Originality of this article: This study proposes an integrated approach to address the impacts of galamsey, combining remote sensing and geospatial technologies with public health and environmental conservation programs. The model can provide a comprehensive understanding of the spatial and temporal impacts of ASGM and enable more targeted interventions.

Динамика биологических показателей возвратных гибридов на основе кастера (калуга Huso dauricus × стерлядь Acipenser ruthenus) (Acipenseridae)

Due to the lack of conditions for industrial sturgeon fishing in the near future, the current artificial reproduction programs play a leading role in replenishing sturgeon populations and commercial sturgeon breeding. It may take a long time to bring the number of individuals and the total biomass of sturgeon fish species in different water basins into proper condition. It is important, along with the implementation of programs for the stocking of young sturgeons of various types of natural habitats, to develop commercial cultivation. Modern aquaculture is the use of environmental control systems, timely feed supply, rapid growth of juveniles with a minimum feed ratio, high survival rate at all stages of growth, greater yield of edible body parts during processing. The dynamics of size and mass indices and the Fulton fatness coefficient in recurrent hybrids of different ages (K × St) are considered × K, (K × St) × St, (St × K) × K and (St × K) × St. It is noted that the fastest growing hybrids turned out to be returnable hybrids based on K × St, and the hybrid (St × K) × St has the highest fatness coefficient with a slight growth rate of weight and length.

From natural marine bacteria and fungi to culturable ones: What affects their bioactivity?

Marine bacteria and fungi have been known as sources of drug candidates. Novel natural products discovery derived from marine bacteria and fungi has been boosted in the last decades. This review discusses the challenges of culturing marine bacteria and fungi taken from their natural habitat into laboratory-scale culturable ones. Since, not all bacteria and fungi, when they are taken from their natural habitat and grown in a laboratory setting, are culturable. This review will also discuss possible solutions to overcome those challenges. Targeted bioactivity relies on the marine bacterial and fungal growth, especially due to the capability on producing the intended natural products. From this review, some important factors that must be taken into consideration to have optimal bacterial and fungal growth are genes and their variation in a species, media composition, and growth condition.

Physiology and fertility of two gull species in relation to plastic additives' exposure

Understanding the impact of plastic and its additives on wild species is crucial as their presence in the environment increases. Polybrominated diphenyl ethers (PBDEs), once used as flame retardants, were restricted due to known toxic effects, but are still detected in the environment. Naturally occurring methoxylated PBDEs (MeO-BDEs) can result from PBDE transformation and may cause similar hazardous effects. Yellow-legged gulls (Larus michahellis, YLG) and Audouin's gulls (Ichthyaetus audouinii, AG) are highly susceptible to plastic additives, due to their distribution, trophic position, and behaviour. In this study, we assessed PBDEs and MeO-BDEs uptake in different tissues and their effects on physiological and reproductive parameters. Findings indicate that, apart from annual differences, adult AG accumulated more MeO-BDEs than YLG in a natural breeding habitat (Deserta), while the latter had lower PBDE levels than YLG breeding in the city of Porto. In relation to chicks, only YLG from Deserta showed higher PBDE concentrations than AG chicks. Individual analysis of each physiological parameter revealed impacts only for adult YLG from Deserta, with neurofunction and immune system inhibition at higher MeO-BDE concentrations. For chicks, AG showed impaired neurofunction, while YLG chicks from Porto exhibited potential genotoxicity effects triggered by higher MeO-BDE levels. Overall health analysis showed activation of antioxidant defences and compromised immune system in YLG adults from Porto due to high values of PBDEs, while chicks from Deserta exhibited inflammation and oxidative stress with high concentrations of MeO-BDEs in the same species. Fertility parameters showed significant differences for sperm counts though suggesting individuals may be able to compensate any exposure effects. This study confirms the widespread presence of plastic-associated compounds and their harmful effects on gulls, particularly on neurofunction, immune system, oxidative balance and fertility, especially due to the presence of MeO-BDEs.

Factors influencing appearance and suitable habitat for wild elephants in the Khao Yai National Park, Thailand

Abstract. Nanla Y, Marod D, Duengkae P, Paansri P, Noowong J, Manitoem C, Sukmasuang R. 2024. Factors influencing appearance and suitable habitat for wild elephants in the Khao Yai National Park, Thailand. Biodiversitas 25: 3061-3072. Protected areas are designated to conserve biodiversity and provide a safe habitat for wildlife. This study aims to investigate the factors affecting elephant appearance and changes in habitat. The maxEnt program was used to analyze data derived from the patrolling system with constant quality monitoring. Four categories of environmental factors, climatic, physiological, biological, and anthropological factors were used to analyze the wild elephant data yearly from 2017 to 2022. The aim was to understand the effect of environmental factors on the wild elephants’ appearance and their habitat suitability. The results showed an average area under the receiver-operating-characteristic curve (AUC) was 0.81±0.004 SD. The results indicated that climatic (42.97%), physiological (32.62%), and anthropological (21.23%) factors affected the appearance of wild elephants significantly. Temperature factors showed the highest percentage contribution (39.04%), while water sources and salt licks, considered physiological factors, contributed 22.13% and 5.06%, respectively. Habitat suitability analysis revealed that the majority of the park area (64.91%) was categorized as unsuited and poorly suited habitat areas, while 35.07% was categorized as moderated and well-suited habitat areas for wild elephants. Implementing strategies to improve water sources and salt lick sites within the park and managing the area to minimize human disturbance both on the surrounding boundaries and the tourist destination sites are recommended to manage the wild elephant.

A Comparative Bryo-Ecological Study of Habitat 3170*: Sites of Particular Phytogeographic Interest in the Mediterranean Area.

In accordance with the 92/43/EEC "Habitats" Directive, Mediterranean temporary ponds are identified as a priority natural habitat within the European context. They are a very interesting and unique habitat type, as ecological conditions can vary greatly in a short period of time. Due to their small size, many Mediterranean hydrophytic bryophytes typical of this habitat are often overlooked or misinterpreted. Their distribution, habitats, ecology, and strategies are generally poorly understood. Several of them are currently considered rare or endangered in the Mediterranean. As these ponds are particularly sensitive to human activities and natural changes, such bryophytes and associated vegetation communities may be at risk. This study is focused on their floristic variability in different environmental conditions in two sites of particular phytogeographic interest in the Mediterranean area. In the Sardinian Pauli of Giara, 56 taxa (50 Bryophyta and 6 Marchantiophyta) were found, and in the Umbria Piana di Ferretto, 54 taxa (34 Bryophyta and 20 Marchantiophyta) were documented. The taxa from the two areas were analysed and compared. Life strategies, life macroforms, light and moisture preferences, chorological elements, and moisture belts were considered. The data are presented here together with information on the phytogeography and ecology of the species recorded. The findings indicate that a bespoke monitoring strategy and dedicated conservation measures are essential for the effective protection of bryophytes, ensuring the achievement of meaningful and sustainable conservation outcomes.

Valuation of Ratargul swamp forest conservation: Does climate knowledge matter?

The degradation of swamp forest ecosystem services due to the adverse effects of climate change has already been observed. Ratargul Swamp Forest (RSF), the only swamp forest in Bangladesh, provides livelihood and ecotourism opportunities for millions. It forms a crucial nexus between the community's economic well-being and the preservation of a unique, ecologically significant natural habitat. However, this ecosystem has experienced severe degradation due to various climatic and anthropogenic factors. Conservation of this unique ecosystem is expected to play a crucial role in addressing climate change and achieving the country's Sustainable Development Goals (SDGs). This study aims to estimate household Willingness to Pay (WTP) and total economic value for this ecosystem using the contingent valuation under a climate change scenario. The mean WTP is estimated to be 7,360.00 BDT, while the total annual benefit of the RSF conservation program is estimated to be 31,798,129.50 BDT per year using a parametric approach. Our result shows that individuals with higher incomes whose primary livelihood depends on this ecosystem, receive benefits from this ecosystem, and have a good understanding of climate change are likely to pay more for the RSF conservation program. Therefore, implementing a communication policy to increase knowledge about climate change would significantly contribute to conserving this unique ecosystem and thus achieve the country's SDGs and the United Nations REED+ program in developing countries.

INTEGRATED PEST MANAGEMENT AND ENTOMOPATHOGENIC FUNGAL BIOTECHNOLOGY IN THE LATIN AMERICAS: I-OPPORTUNITIES IN A GLOBALAGRICULTURE

Entomopathogenic fungi (EPF) have been used as insect biocontrol agents separately and in integrated pest management (1PM) worldwide including in the Latin Americas. The proper use of these agents along with other elements and concepts of 1PM has significant impact on the provision of crops. fruits and other agricultura! products Entomopathogenic fungi can play a significant role in the preservation of the natural delicate balance of beneficia! biota and their active spreading from the surrounding natural habitats, such as the tropical rain forest, the humid cloudy forest in the Andes and other important ecosystems, to the agricultura} lands in Central and South America. Of ali known EPF, there are only about half a dozen for which prerequisite aspects of fungal biotechnology for industrial R and D are in place. Because of its precedent setting leadership in the use ofEPF in 1PM and agroecological practices, LatinAmerica stands to gain irnrnensely here and more so if the concept of rational design of bioinsecticides (RADBIO) is employed. The future prospects will depend on a balance of discovery research coupled to a strong and dependable industrialization effort to develop the framework for illustrating public acceptance, commercialization potential and widespread use of EPF in 1PM. The potential for the next generation of mycoinsecticides is now loorning on the horizon.
