An annotated checklist of the mammals of the Chimanimani National Park, Mozambique

The Chimanimani Mountains of Mozambique and Zimbabwe harbour diverse and unique flora and fauna. Because of these unique floral characteristics, this region has received considerable attention by botanists. In contrast, the vertebrates occurring here have received little attention. The aim of this paper was to synthesise data collected on multiple recent surveys into the first annotated checklist of the mammals of the Mozambican side of the Chimanimani Mountains. We identified medium-sized and large mammals by exterior appearance, mostly as captured on camera traps. We combined morphological and molecular methods to identify small mammals, and we report on echolocation calls of some of the poorly known bat species. In total, we recorded 69 species, including 23 species of bats (Chiroptera), 15 species of rodents (Rodentia), 11 species of carnivores (Carnivora), nine species of ungulates (Cetartiodactyla), and the rest comprising Primates, Eulipotyphla, Lagomorpha, Proboscidea, and Pholidota. Of these, five species are listed as threatened, demonstrating the importance of the Chimanimani Mountains for mammalian biodiversity conservation in South Eastern Africa.

Estimating mean groundwater levels in peatlands using a Bayesian belief network approach with remote sensing data

Large-scale management, protection, and restoration of wetlands require knowledge of their hydrology, i.e., the status and dynamics of the groundwater table, which determine the evolution of the wetland ecosystem, its conservation value, and possible economic use. Unfortunately, in many cases, hydrological monitoring data are unavailable, resulting in the search for a proxy for the average annual depth of the groundwater level (GWL). This study presents an approach to estimating the mean GWL in peatlands using a Bayesian belief network (BBN) model, leveraging long-term hydrological and remote sensing data in the Biebrza National Park in Poland. The remote sensing data employed includes the synthetic aperture radar (SAR) backscatter coefficient, peat subsidence, rate and distance to watercourses. The BBN model achieved a predictive accuracy of 83.3% and 73.1%, depending on the validation approach used. Among the remote sensing variables considered, the SAR backscatter coefficient was the most sensitive in predicting the GWL in the peatlands. However, the model presents multiple uncertainties resulting from limitations of the available remote sensing data, low variability of class combinations in the conditional probability table, and lack of upscaling to other regions performed. Despite these uncertainties, the developed BBN model remains a valuable next step in reaching the goal of efficient peatland monitoring and management.

Impact of drought and development on the effectiveness of beehive fences as elephant deterrents over 9 years in Kenya

AbstractHuman–elephant conflict is growing in Africa as human populations and development increases, creating disturbance to elephant habitats. Beehive fences have been trialed as a coexistence tool with some success but all studies have looked at small sample sizes over a short time period. Our study analyses the behavior of African elephants (Loxodonta africana) that approached a network of beehive fence protected farms in two conflict villages over 9 years next to Tsavo East National Park. We compare differences in elephant raids and beehive occupation rates annually, during a drought, and during peak crop production seasons. Out of 3999 elephants approaching our study farms 1007 elephants broke the beehive fence and entered the protected farm areas (25.18%). This was significantly less than the 2649 encounters where elephants remained either outside the farm boundary or broke into the control farms (66.24%). A further 343 elephants entered the farm by walking through a gap at the end of a fence (8.56%). The annual beehive fence break‐through rates averaged 23.96% (±SE 3.15) resulting in a mean of 76.04% elephants deterred from beehive fences protected farm plots. Over six peak crop growing seasons the beehive fences kept between 78.3% and 86.3% of elephants out of the farms and crops. The beehive fences produced one ton of honey sold for $2250; however, a drought caused a 75% reduction in hive occupation rates and honey production for 3 years after negatively impacting honey profits and the effectiveness of the fences. Beehive fences are very effective at reducing up to 86.3% of elephant crop‐raids during peak crop seasons after good rainfall, but any increase in elephant habitat disturbance or the frequency and duration of droughts could reduce their effectiveness as a successful coexistence tool.

A targeted study to determine the conservation status of a Data Deficient montane lizard, the Eungella shadeskink (Saproscincus eungellensis)

Context Combatting biodiversity loss is often hamstrung by a lack of species-specific knowledge. Species considered Data Deficient (DD) on the IUCN Red List are poorly understood and often neglected in conservation investment, despite evidence they are often threatened. Reptiles have the highest percentage of DD species for any terrestrial vertebrate group. Aims We aimed to assess the conservation status of the DD Eungella shadeskink (Saproscincus eungellensis), which is endemic to Eungella National Park, Queensland, Australia. Methods A combination of a targeted field survey, ecological studies, and species distribution modelling were used. Key results Saproscincus eungellensis typically occurred within 25 m of streams, at elevations between 700 and 1000 m. The species is thigmothermic, with a low active body temperature (~23–26°C) and was predominantly observed on rocks and fallen palm fronds. The species has a highly restricted distribution with an estimated Area of Occupancy of 36 km2 and Extent of Occurrence of 81.7 km2, comprising one location (defined by the threat of climate change) with an estimated 16,352–52,892 mature individuals. The main threats are fire, invasive alien species and climate change, with the species forecast to lose all suitable habitat by 2080 under all climate change scenarios. Conclusions The species meets listing criteria for Critically Endangered under Criterion B of the International Union for Conservation of Nature. Implications Our results support recent studies indicating that some DD species are highly threatened. Our approach provides a template for conducting targeted studies to determine the conservation status of DD species, especially those with restricted ranges.

Revitalization of Tourism Village Facilities as an Effort to Increase Income and Sustainability

Developing village tourism in Indonesia is a crucial government strategy to boost the local economy and increase regional income. Villages with diverse assets such as natural beauty, rich cultural traditions, traditional cuisine, handicrafts, and historical sites have the potential to become attractive tourist destinations. This research focuses on Gunung Wangi Nature Tourism, which offers attractions such as sunset views, city lights at night, and camping activities. However, constraints such as inadequate facilities and infrastructure are the main focus of this research. Through a Community-Based Participatory Research (CBPR) approach, this research offers solutions to revitalize the facilities and infrastructure and a long-term revitalization strategy to increase the attractiveness of Gunung Wangi. Local community involvement is integrated into every research stage, including problem identification, Focus Group Discussion (FGD), implementation, and evaluation. Revitalization efforts at Gunung Wangi Nature Park have shown positive results, with substantial improvements reported in post-revitalization evaluations. Feedback from stakeholders, including visitors, MSME players, and Gunung Wangi Tourism village managers, showed significant improvements in infrastructure and visitor experience. While a few respondents suggested room for improvement, the overall success is evident in the increase in visitor numbers, with the majority experiencing a significant increase. This revitalization has rejuvenated this tourist spot's attractiveness and boosted economic growth in the local community

Performing the changing landscape

This exposition refers to arts-based research on simultaneous performative walking and singing practice in a changing environment. The act of walking is put in the context of landscape and singing representing two aspects of relation to the environment – inner and outer landscape. The object of research is traditional and authorial songs and their bodily and sensual interconnection with the process of experiencing landscape. This experience is gained with a group of artists and environmentalists who have over the course of more than a year repetitively walked through the landscape of the natural park Prokop Valley in Prague and its adjacent urban areas. Qualitative research is taken within the project “Walking as a liquid constant in urban space and landscape”. The method of data collection uses mental maps, inspired by the concept of Kevin Lynch, as a means of documentation. The exposition has three parts 1) the opening video essay, 2) Opus caementicium, autoethnographic reflection of the site, where the project takes place, and 3) Fugue of the vanishing world – an essay on the musical aspect of the project. Chapter titles are inspired by musical terminology that has content connotations in the text or mirrors the structuring of text and musical compositions.

Discreet but diverse and specific: Determining plant‐herbivore interactions across a species‐rich plant family in a tropical rain forest

AbstractStudying plant–herbivore interactions within tropical rain forests is fundamental to understanding their ecology and evolution. An important aspect of plant–herbivore dynamics is the role of temporal and taxonomic variables in determining associations between herbivores and their host. Using the diverse and chemically rich plant family Annonaceae (Magnoliales), we conducted a year‐long study in Ecuador's Yasuní National Park in lowland Amazonia. We focused on nine understory tree species across a broad phylogenetic range within Annonaceae. For these species, we investigated patterns of herbivory, identified herbivores through DNA barcoding, and documented unique ant–butterfly associations. In general, leaf damage ranged from 0.09% to 25%, with significant temporal fluctuations for three species. Notably, Anaxagorea brevipes and Unonopsis veneficiorum faced higher herbivore pressure when compared to the other studied species. We document a discreet but diverse herbivore community, with 40 larvae from 12 Lepidoptera families collected throughout the year. Our findings identify, for the first time across a phylogenetically diverse sampling of Annonaceae, the specialization of herbivores on our focal species. Overall, our data provide valuable information on herbivory patterns at the local scale for this important rain forest plant family. Furthermore, these findings contribute to our understanding of the ecological processes that influence plant species diversity in tropical rain forests.Abstract in Spanish is available with online material.

Diversity and Population of Ducks and Geese in Keibul Lamjao National Park (KLNP) in Manipur, India

As a part of the Asian Waterbird Census (AWC), surveys on ducks and geese were made at five (5) major waterbird congregation sites of Keibul Lamjao National Park (KLNP) during 2020-2024. A total of 18 species of ducks and two species of geese belonging to the family of Anatidae were recorded during the period. The duck species includes 14 migratory and 4 resident species and the two migratory geese species. Lesser Whistling Duck Dendrocygna javanica was the most abundant and dominant species in terms of population followed by Gadwall Anas strepera and Red - crested Pochard Netta rufina and minimum value was observed in Greylag Goose Anser anser. The Critically Endangered Baer’s Pochard Aythya fuligula was recorded in the year 2023 at Pabot Chingmang site (2 individuals). Another two globally Near threatened (NT) Ferruginous Pochard Aythya nyroca and Falcated Duck Anas falcata have been recorded here.

Possible effects of shipping routes on coral reef degradation and diversity in Karimunjawa Marine National Park, Java Sea

The Karimunjawa Marine National Park, situated in the Java Sea, Indonesia, is renowned for its rich biodiversity and lively coral reefs. However, amidst the backdrop of this natural beauty, concerns have been raised regarding the potential impacts of shipping activities on the health and diversity of these fragile ecosystems. The increase in maritime traffic, including commercial vessels, tourist boats, and fishing vessels, traversing through the Karimunjawa Marine National Park, raises significant environmental concerns. The movement of these vessels, especially along specific shipping routes, has the potential to disturb and damage coral reefs through various mechanisms. Hence, this study aimed to investigate the possible impacts of shipping routes on the coral abundance and diversity and the coral health in the Karimunjawa Islands, Java Sea, Indonesia. This study categorized ship routes into West Route, East Route, and Non-Route and assessed coral health and diversity across 15 islands. Key metrics analyzed included coral disease prevalence, coral cover, diversity index, species richness, relative abundance, and evenness, using 15 × 2 m belt transects at 3 and 8 m depths with three repetitions each. Statistical analysis revealed significant differences in coral abundance and species richness among ship-route groups, but no significant depth-related differences. These results suggest that while shipping routes affect certain aspects of coral health and diversity, other factors may be more influential in shaping coral disease prevalence and overall diversity in Karimunjawa reefs.

Storm surge, seawater flooding, and sea-level rise paradoxically drive fresh surface water expansion

Abstract Coastal storms and sea-level rise are expected to increase seawater flooding in low-elevation coastal zones. High sea levels and seawater flooding can drive groundwater table rise via ocean-aquifer connections. These dynamics are often overlooked but can cause groundwater flooding and salinization hazards, increasing freshwater security challenges for coastal communities and driving ecosystem transgressions. Field data and numerical modeling were used to evaluate how heavy rainfall, storm surge, and seawater flooding and infiltration during Hurricane Fiona (September 2022) and projected sea-level rise impact groundwater levels, inland surface waters, and saltwater intrusion on Sable Island National Park Reserve, Canada. During the passage of Hurricane Fiona, precipitation increased groundwater and pond levels before seawater flooded the beach. Seawater flooding and infiltration caused a sharp rise in beach groundwater levels, which in turn caused inland pond levels to rise without coincident direct inputs from precipitation or seawater. Model simulations reveal that seawater infiltration on beaches flooded the subsurface and drove the observed inland groundwater rise and freshwater pond expansion. Simulations of projected sea-level rise show that seawater flooding will only inundate a small area of land along the coast; however, inland groundwater rise and flooding, which is less well-studied, may inundate up to 30 times more land area. Further, groundwater flooding driven by rising sea levels decreases hydraulic gradients and increases saltwater intrusion via freshwater lens contraction. Findings demonstrate that seawater flooding from coastal storms and sea-level rise paradoxically cause concurrent fresh surface water expansion but freshwater lens contraction. This study provides new insights into the spatiotemporal dynamics of island freshwater resources and highlights that unseen and often overlooked groundwater-surface water exchanges are critical to consider when evaluating coastal flooding and groundwater salinization hazards and management strategies for low-elevation coastlines.

New species of the genus Alippistrongylus (Nematoda: Trichostrongylina) parasitic in Delomys dorsalis (Rodentia: Sigmodontinae) in the Atlantic Forest of Rio de Janeiro, Brazil.

We describe a new species of the genus Alippistrongylus (Nematoda: Trichostrongylina) in the small intestine of Delomys dorsalis (Rodentia: Sigmodontinae) found in Itatiaia National Park (Parque Nacional do Itatiaia, PNI), state of Rio de Janeiro, Brazil. The new species can be distinguished between the other two species previously described by the following morphological characteristics: pattern of the rays from the caudal bursa rays in males and the spherical-shaped appendage in the female. Additionally, we provide molecular genetic data from the new species. The discovery of Alippistrongylus itatiaiaensis sp. n. expands our understanding of nematode diversity and underscores the importance of parasite studies in biodiversity conservation. Its occurrence in a preserved area like the PNI emphasises the role of such habitats in maintaining unique ecological interactions.

The projected exposure and response of a natural barrier island system to climate-driven coastal hazards

Accelerating sea level rise (SLR) and changing storm patterns will increasingly expose barrier islands to coastal hazards, including flooding, erosion, and rising groundwater tables. We assess the exposure of Cape Lookout National Seashore, a barrier island system in North Carolina (USA), to projected SLR and storm hazards over the twenty-first century. We estimate that with 0.5 m of SLR, 47% of current subaerial barrier island area would be flooded daily, and the 1-year return period storm would flood 74%. For 20-year return period storms, over 85% is projected to be flooded for any SLR. The modelled groundwater table is already shallow (< 2 m deep), and while projected to shoal to the land surface with SLR, marine flooding is projected to overtake areas with emergent groundwater. Projected shoreline retreat reaches an average of 178 m with 1 m of SLR and no interventions, which is over 60% of the current island width at narrower locations. Compounding these hazards is subsidence, with one-third of the study area currently lowering at > 2 mm/yr. Our results demonstrate the difficulty of managing natural barrier systems such as those managed by federal park systems tasked with maintaining natural ecosystems and protecting cultural resources.

Unveiling the Secrets: How Landscape Patterns Shape Habitat Quality in Northeast China Tiger and Leopard National Park

The Northeast China Tiger and Leopard National Park (NCTLNP) is a critical habitat for the endangered Amur tiger and Amur leopard, making it a global biodiversity hotspot. This study explores how changes in landscape patterns have influenced habitat quality in the park, aiming to develop strategies for enhancing biodiversity conservation and ensuring the park’s long-term sustainability. From 2012 to 2017, habitat quality in the NCTLNP experienced a significant decline; however, the launch of the national park pilot program in 2017 resulted in improvements, particularly in core protected areas, where habitat quality increased and landscape fragmentation decreased. These findings indicate that the national park initiative reduced the degradation of habitat quality. Key landscape metrics, especially the Shannon Diversity Index (SHDI), were found to significantly affect habitat quality. Additionally, the interaction between SHDI and landscape contagion (CONTAG) played a pivotal role in shaping habitat quality over time. Areas with high SHDI and low CONTAG showed declines in habitat quality, pointing to the need for focused conservation efforts. This study offers valuable insights for policymakers seeking to improve habitat quality through targeted landscape management practices.

Community-Led Participatory Forest Monitoring for the Restoration of Kibale National Park (KNP) in Western Uganda

This paper presents findings from a study on Participatory Forest Monitoring (PFM) and Natural Forest Restoration (NFR) in Uganda, a case of communities bordering Kibale National Park (KNP), Uganda was conducted among 394 respondents from June to August 2024. The study adopted a cross-sectional research design to determine participatory Forest Monitoring Activities and Practices. A questionnaire was designed and distributed to collect responses and data was analysed using MS Excel. Findings reveal that more males (55.58%) participated in PFM compared to 44.42 females, most females were involved in raising seedlings for restoration of KNP. The majority (83.76%) of them were farmers. Over 46.09% of the households were employed by the Uganda Wildlife Authority Forests Absorbing Carbon Emission (UWA-FACE) project and living within 1 kilometre of the park boundary. Tree planting through reforestation of degraded and reclaimed areas was the main PFM activity at 51%. Participation in PFM was through signing a Memorandum of Understanding. Only 24% of the households signed an MOU with UWA-FACE to participate in PFM programmes. Of the 394 respondents surveyed, 79.2% strongly agreed that they engaged in selecting tree species to raise for restoration activities to improve the management of Kibale National Park (M=1.88, SD = 1.97). Almost half (54.4%) of the communities bordering Kibale National Park (KNP) work with UWA rangers during forest monitoring patrols in restored areas (M=2.25, SD = 1.95). PFM can restore natural forests. There is a need to increase support for community projects by UWA-FACE.

A self‐cooling self‐humidifying mosquito carrier backpack for transporting live adult mosquitoes on foot over long distances under challenging field conditions

AbstractIt is often necessary to use motorised transport to move live mosquitoes from distant field collection points into a central insectary, so that their behavioural and/or physiological phenotypes can be assessed under carefully controlled conditions. However, a survey of heritable insecticide susceptibility traits among wild‐caught Anopheles arabiensis mosquitoes, collected across an extensive study area composed largely of wilderness in southern Tanzania, necessitated that live mosquitoes were carried on foot over distances up to 25 km per day because most of the area was impassable by car, motorcycle or even bicycle during the rains. A self‐cooling, self‐humidifying carrier backpack was therefore developed that allows live adult mosquito specimens to be transported across rugged miombo woodland and floodplain terrain throughout the year. This wettable backpack was fabricated from stitched Tanzanian kitenge cotton fabric and polyvinyl chloride–coated fibreglass netting that allows easy circulation of air in and out. An outer cover flap made of cotton towelling embedded inside a kitenge envelope overhangs the fibreglass netting upper body of the bag, to protect mosquitoes from direct sunlight, and can be soaked with water to maintain low temperature and high humidity inside. Mean survival of insectary‐reared female An. arabiensis transported through nine different mobile camps inside the 509 km2 Ifakara‐Lupiro‐Mang'ula wildlife management area (ILUMA WMA), over up to 143 km and 25 days, was statistically indistinguishable from those left in the field insectary over the same period. Although considerable variance of survival was observed between different batches of mosquitoes from the insectary and between individual cups of mosquitoes, the different levels and positions inside the backpack had no influence on this outcome. Temperature and humidity inside the backpack were maintained at standard insectary conditions throughout, despite much more extreme conditions immediately outside. When the backpack was used to transport wild An. arabiensis and Anopheles quadriannulatus across a much larger study area of &gt;4000 km2, encompassing the ILUMA WMA, some nearby villages and adjacent parts of Nyerere National Park (NNP), it achieved a mean survival rate of 58.2% (95% confidence interval 47.5–68.2). Encouragingly, no difference in survival was observed between ILUMA WMA and NNP even though transport back from NNP involves much longer distances, sometimes involving lengthy journeys by car or boat. Overall, this mosquito carrier backpack prototype appears to represent a viable and effective method for transporting live wild‐caught mosquitoes on foot across otherwise impassable terrain under challenging weather conditions with minimal detrimental impact on their survival.

Effects of human disturbance on the distribution and abundance of large mammals in Abijata-Shalla Lakes National Park, Ethiopia

The increasing human pressure has threatened wildlife conservation, even in protected areas. However, findings reporting the effects of human on wildlife conservation are not consistent. This study aimed to investigate the effect of human disturbance on the distribution and abundance of mammals in Abijata-Shalla Lakes National Park considering the consumptive and non-consumptive modes of human activities. The study was conducted from September 2017 to February 2018 in three selected sites, which were stratified based on human disturbance as nature conserved areas, sites engaged in consumptive livelihood, and ecotourism sites. Data were collected using a line transect method. The distribution and abundance data were analyzed using Chi-square tests and one-way ANOVA, respectively. There was a significant difference on the distribution of target wild animals in the selected sites; greater kudu (P < 0.001), warthog (P < 0.01), and bohor reedbuck (P = 0.03) were highest in the “nature conserved” site. Human disturbance also significantly affected the abundance of warthog (P = 0.028), greater kudu (P < 0.001), and bohor reedbuck (P = 0.024). Greater kudu distribution was limited in nature conserved site. However, Warthog and Bohor Reedbuck were distributed in all sampling sites; nature conserved sites hold the highest population abundance. The results indicate that consumptive local livelihood and ecotourism disturbances adversely affected the distribution and abundance of mammals relative to the nature reserved site. However, ecotourism favored some mammal species from the consumptive local people’s livelihood activities. Thus, to reduce the impact of human disturbances on wildlife conservation, monitoring and controlling the level of human disturbance is urgent. Sustainable practices such as community engagement, awareness creation and alternative livelihood options should be proposed.

The Jurassic Park and Ata Modo in Eastern Indonesia

Famous for its distinctive Komodo dragons (Varanus Komodoensis) and features home to underwater ecosystems, the Komodo National Park (KNP) has become a prominent and favorite destination of visitors locally and globally in recent years. Situated in Labuan Bajo, East Nusa Tenggara Province, Indonesia, KNP has three prime islands: Rinca, Komodo, and Padar. The infrastructure development in KNP formulated in 2020 by the central government of Indonesia, including establishing offices, photograph areas, clinics, warehouses, public spaces, and tour guides' offices, raises controversy about this decision. While the government of Indonesia persuaded citizens that this erection was a conservation effort for protection, preservation, and utilization, UNESCO refused this plan by enacting a refusal document and assessing whether the development could affect the property's Outstanding Universal Value (OUV) before the review of the relevant environmental impact analysis by the International Union for Conservation of Nature (IUCN). Additionally, the local people argue this plan will threaten the giant lizard's habitat regarding the entry of heavy equipment and disadvantage local tourism actors. Using a systematic literature review method, this piece collects and discovers a different concept in the issue of infrastructure development in KNP instead of another scholar's perspective. Walpole and Goodwin (2000) find that economics and facilities are the prominent aspects of tourism, while UNESCO considers the environment in development. In contrast to popular belief, this paper indicates a significant role of local people, known as Ata Modo, in the KNP establishment. This paper's findings propose that Ata Modo, as local people/tribes in KNP, should not be relocated from their area and instead be involved in the decision-making process. The bottom-up approach can be executed as a practice in a democratic process. From the fiscal approach, this development will positively impact local people's economy through collaboration and stakeholder participation.

Genetic diversity of Bartonella species in small mammals in the Qinghai Menyuan section of Qilian Mountain National Park, China

Bartonella are vector-borne gram-negative facultative intracellular bacteria that can infect a wide spectrum of mammals, and are recognized as emerging human pathogens. This study aimed to investigate the prevalence and molecular characteristics of Bartonella infections in small mammals within the Qinghai Menyuan section of Qilian Mountain National Park, China. Small mammals were captured, and the liver, spleen and kidney were collected for Bartonella detection and identification using a combination of real-time PCR targeting the transfer-mRNA (ssrA) gene and followed by sequencing of the citrate synthase (gltA) gene. A total of 52 rodents were captured, and 36 rodents were positive for Bartonella, with a positivity rate of 69.23% (36/52). Bartonella was detected in Cricetulus longicaudatus, Microtus oeconomus, Mus musculus, and Ochotona cansus. The positivity rate was significantly different in the different habitats. Two Bartonella species were observed, including Bartonella grahamii and Bartonella heixiaziensis, and B. grahamii was the dominant epidemic strain in this area. Phylogenetic analysis showed that B. grahamii mainly clustered into two clusters, which were closely related to the Apodemus isolates from China and Japan and the local plateau pika isolates, respectively. In addition, genetic polymorphism analysis showed that B. grahamii had high genetic diversity, and its haplotype had certain regional differences and host specificity. Overall, high prevalence of Bartonella in small mammals in the Qinghai Menyuan section of Qilian Mountain National Park. B. grahamii is the dominant strain with high genetic diversity and potential pathogenicity to humans, and corresponding control measures should be considered.
