Wildlife conservation society’s activities and biodiversity conservation in protected areas in cross river state, Nigeria

Despite the activities of the Wildlife Conservation Society (WCS) in protected areas in Cross River State, a high level of forest resource exploitation is still occasioned by indiscriminate logging, wildlife poaching, bush burning, and dangerous fishing. Previous studies in the study area and Africa have identified some reasons for this continuous biodiversity exploitation. However, the effect of the activities of the WCS has yet to be analyzed. This study used a correlational research design to examine the Wildlife Conservation Society's (WCS) activities and biodiversity conservation in Protected Areas in Cross River State. A sample of 1360 respondents from a population of 76,704 inhabitants in the 25 support Zone Communities in Afi, Mbe, and Okwangwo Divisions of Cross River National Park (CRNP) was drawn. After receiving face and content validity from experts, a 30-item structured questionnaire was used for data collection. The instrument's Cronbach alpha reliability indices varied between 0.83 and 0.89. The data analysis method employed was Simple Linear Regression analysis. The analysis revealed that conservation education activities, alternative livelihood support, and anti-poaching patrols significantly contributed to biodiversity conservation in Protected Areas in Cross River State. Based on this result, it was concluded that the activities of WCS to ensure adequate conservation of biodiversity-ecosystem in Protected Areas in Cross River State yield intermediate results. It was recommended that WCS intensify efforts in educating community people around protected areas in Cross River State, increase and monitor alternative livelihood support, and intensify anti-poaching patrols in all the protected areas.

“Saving the Forest” with a REDD+ Project: Socio-Ecological Repercussions on Indigenous People in Cambodia

With the ecological threat associated with climate change and biodiversity loss, the push to expand green zones with minimal human presence is gaining momentum, especially in the Global South. In line with this worldwide tendency, the Kingdom of Cambodia has embarked on a long-term strategy for carbon neutrality, aiming to achieve zero emissions by 2050, making it the first in ASEAN to submit such a vision. Protecting the forest is the present-day motto. Beyond this mainstream rhetoric, this article delves into the survival realities of the indigenous people involved in Cambodia's conservation projects. The anthropological research intends to reveal the fate of the villages (human rights, access to land and natural resources, sovereignty) living in and around a conservation area. We examine the case of the transnational organisation Wildlife Conservation Society engaged in a Reducing Emissions from Deforestation and Forest Degradation (REDD+) program in a territory traditionally inhabited by ethnic Bunong people. The findings provide significant insights, frequently neglected, into the challenges associated with the will to “save the forest”, with an extremely limited participation of the local population.

Comparing forest product harvest rates and livelihood activities among migrant and Indigenous households in the Congo Basin

Understanding uneven patterns of forest use and tracking changes in the composition of forest residents are both important for sensitive forest policy and management. With increases in migration streams in several tropical forest regions, we need corresponding information about how new immigrants are influencing human-environment relations in sites of ecological significance. We use data from over 6500 household surveys collected by the Wildlife Conservation Society in three sites in Central Africa: the forests surrounding Nouabalé-Ndoki National Park and Lac Télé Community Reserve in the Republic of Congo, and the Okapi Wildlife Reserve in the Democratic Republic of Congo. We compare household characteristics, livelihoods, and forest use among recent migrants (arriving within the past decade), longer-established households, and households belonging to an Indigenous group. We find that recent migrants are less likely to engage in forest-harvest-based livelihoods and harvest several types of forest foods and fibers less frequently than other households. Recent migrants also tend to be wealthier, younger, and over-represented in salaried jobs. Meanwhile, Indigenous households are 3 to 16 times more likely to participate in a forest-based livelihood, depending on the site. Other consistent predictors of forest harvest include village, age of the household head, household size, whether a household is female-headed (−), and wealth (−). Many trends hold broadly across all three sites, but there are also site-specific patterns related to differences in remoteness and economic opportunities. We conclude with reflections about what the changing make-up of forest-proximate communities might mean for forest management and governance.

Exploring the emergence of a tipping point for conservation with increased recognition of social considerations.

Despite a common understanding of the harmful impacts of Western conservation models that separate people from nature, widespread progress toward incorporating socioeconomic, political, cultural, and spiritual considerations in conservation practice is lacking. For some, the concept of nature-based solutions (NbS) is seen as an interdisciplinary and holistic pathway to better integrate human well-being in conservation. We examined how conservation practitioners in the United States view NbS and how social considerations are or are not incorporated in conservation adaptation projects. We interviewed 28 individuals working on 15 different such projects associated with the Wildlife Conservation Society's Climate Adaptation Fund. We completed 2 rounds of iterative coding in NVivo 12.6.1 to identify in the full text of all interview responses an a priori set of themes related to our research questions and emergent themes. Many respondents saw this moment as a tipping point for the field (one in which the perceived values of social considerations are increasing in conservation practice) (76%) and that social justice concerns and the need to overcome racist and colonial roots of Western conservation have risen to the forefront. Respondents also tentatively agreed that NbS in conservation could support social and ecological outcomes for conservation, but that it was far from guaranteed. Despite individual intention and awareness among practitioners to incorporate social considerations in conservation practice, structural barriers, including limited funding and inflexible grant structures, continue to constrain systemic change. Ultimately, systemic changes that address power and justice in policy and practice are required to leverage this moment to more fully address social considerations in conservation.

Large-scale monitoring in the DRC’s Ituri forest with a locally informed multidimensional well-being index

To monitor quality of life in changing landscapes and assess impacts of interventions, development scholars and practitioners continue to seek sensitive, flexible, practical means of measuring well-being. An approach that has received relatively little attention from development scholars but that is gaining traction among NGOs is the use of a well-being index derived from a list of locally defined and democratically weighted basic necessities. The Wildlife Conservation Society has been piloting a tool called the Basic Necessities Survey (BNS) in and around protected areas in Central Africa and beyond for over a decade. Adapted from consensual relative poverty metrics developed in the UK and Sweden, BNS data can be used to calculate a Well-being Index (WBI) that is locally relevant and comparable. To demonstrate its applicability in a lower-income context, we present findings from the Ituri Region of the Democratic Republic of the Congo (DRC) where over 2,000 households were surveyed using the BNS tool in 2015, 2017, and 2019. WBI scores were lower among traditionally vulnerable and marginalized groups: Indigenous and female-headed households, those with young or elderly heads, and households that were smaller or had high ratios of dependents. WBI varied with livelihood and geography and was sensitive enough to detect group-specific changes over a short time; namely an economic shock concentrated in villages along the main local highway in 2017 when the DRC experienced a major currency devaluation. Scores can be calculated to either incorporate or isolate variability in subjective expectations about what constitutes well-being; we show that expectations differed for Indigenous households and expectations rose faster than assets in this period. Findings build confidence in the utility of this type of locally informed multidimensional well-being metric in low-income regions. Those seeking practical instruments to produce flexible and regionally comparable well-being measures may wish to consider this approach.

Hibernating bats may use protein stores for water balance

All hibernating bats need to eat enormous amounts of food during autumn to build up a substantial fat store for hibernation. These large fat stores supply the immense amount of energy needed to survive without access to food and water. However, little is known about how the breakdown of proteins from muscles and organs contribute to the hibernating animal's energy stores and possibly their water budget. Liam McGuire from Texas Tech University, USA (now at the University of Waterloo, Canada), and colleagues from Montanan State University, Texas Tech University and the Wildlife Conservation Society, all in the USA, set out to investigate how proteins from the muscles and organs of two species of bats are used for energy and water during hibernation.In October 2016, before the bats entered hibernation, the team observed 184 cave myotis (Myotis velifer) in a cave in Oklahoma, taking measurements of the animals’ forearm length (a measurement of body size), determining their sex and using a mobile laboratory to measure the amount of fat, muscle and organ masses. Next, the team collected the same measurements from 65 Townsend's big-eared bats (Corynorhinus townsendii) at two caves in eastern Nevada during both the fall and winters of 2017–2019 to track changes in the fat, muscle and organ masses as the animals hibernated. Then, the team calculated the amount of energy and water generated by the Townsends’ big-eared bats from the decreases in fat, muscle and organ mass.McGuire and colleagues found that prior to entering hibernation, muscle and organ masses in the cave myotis was ∼25–38% of the animals’ total body mass. The team suspect that during this period, the bats build up their digestive organs to allow them to binge and build up their fat reserves in addition to bulking up their muscles to carry the large fat store. However, larger muscles and organs also provide bats with access to protein throughout hibernation. In addition, the males had proportionally larger muscles and organs, whereas the females had more body fat, which the researchers suggested may be due to differences in the animals’ reproduction strategies. Females need to conserve energy reserves throughout hibernation in preparation for possible pregnancies following hibernation. With their larger protein stores, the males have greater flexibility when arousing from hibernation to burn through organs and muscle to fuel their energy and water requirements, as protein breakdown produces more water compared to fat. But how did the hibernating big-eared bat reserves hold during their long hibernations?The males consumed approximately twice the amount of muscle and organ tissue than the females, accounting for 35% of the males’ total body mass loss and contributing 7% of the energy they used during hibernation. The females, however, had more body fat and were able to generate more energy as fat produces larger amounts of energy relative to protein. The researchers calculated how much water the animals generate as they both broke down muscle and organs and discovered that, after they subtracted the additional water that the animals lost excreting the toxic waste products generated by consuming protein, the female bats benefited by retaining four times more of the water they generated than the males. The team argues that bats could potentially use protein breakdown for hydration during hibernation.McGuire and colleagues have successfully shown that bats build up their muscles and organs prior to hibernation, which could be used as a minor source of energy but could also play a major role in the production of water. Relatively little is known about how hibernating bats using protein as a source of water, but this new study opens the flood gates to new avenues in bat hibernation research.

Tailoring social safeguards in conservation to reflect the local context and level of risk

This evidence piece argues that social safeguards in the context of conservation should not be put in place using a formulaic, one size fits all approach Rather safeguards should be tailored to the conservation approaches and actions being implement and the social risks. The piece uses the Wildlife Conservation Society as an example of how a tailored approach is being implemented in the field.

Reduction in Firewood Consumption due to Implementation of Improved Cookstoves in Melghat Tiger Reserve, India

According to the 2001 Census of India, around 82% of the rural population of India depends entirely on biomass and uses primitive cookstoves for cooking. The smoke released due to incomplete combustion causes several chronic respiratory disorders among women responsible for cooking. Despite these adverse effects, people continue to use traditional cookstoves due to their simplicity. Firewood consumption is also responsible for the degradation of forests and the emission of CO2, which is a major greenhouse gas. A project was implemented by Wildlife Research and Conservation Society in 12 villages in Melghat Tiger Reserve to introduce improved cook stoves in 1,098 households for reducing firewood consumption and smoke emission. This study estimated that the improved cookstoves (ICS) had reduced the average per capita firewood consumption by 0.61 kg/day (25%) and resulted in the conservation of 1,171 tons of firewood annually. A decrease of 1,953 tons of CO2 emissions due to the installation of ICS has been estimated. Installation of ICS reduced the time taken to cook a meal by an average of 40 minutes and reduced smoke production, thereby contributing to the health of the users.

Connecting workplace attachment and pro-environmental behaviors in zoo andaquarium professionals.

Emerging conservation psychology literature shows that there is a strong link between positive attachment to a workplace and the performance of pro-environmental behaviors by employees at work. The present study explores the validity of a pilot survey based in previous literature that explores these constructs to determine whether a relationship between the two exists among zoo and aquarium professionals. The survey was distributed to employees of the Wildlife Conservation Society's city zoos-Prospect Park, Central Park, and Queens Zoos-during the first year of the SARS-CoV-2 pandemic. Two of the survey scales used had a high internal consistency and data from these responses informed this case study to show that there is a weak, positive correlation between workplace attachment (WPA) and self-reported frequency of performance of pro-environmental behaviors (PEBs) among the respondents. Isolating the responses by department revealed that staff working in Operations departments (1) exhibit lower frequencies of PEB than those in Education and Animal departments and (2) have a very strong, positive correlation between WPA and PEB. The results suggest that zoo and aquarium employees who are positively attached to their workplace are more likely to perform PEBs, especially those working in Operations departments. These findings help support that workplace practices seeking to increase WPA could increase the performance of PEBs at work by all employees.

The landscape of climate change adaptation aspirations in the US non‐profit conservation sector

AbstractDespite extensive recommendations for adapting conservation to climate change, limited knowledge exists about how practitioners aim to respond. To address this gap, we analyzed proposals for on‐the‐ground climate adaptation projects submitted by US conservation non‐profits, which play a central role in conserving biodiversity. We assessed 415 proposals submitted between 2011 and 2015 to the Wildlife Conservation Society's Climate Adaptation Fund, a US‐based fund focused solely on adaptation for wildlife and ecosystems. We evaluated the distribution of proposed projects across conservation targets, strategies, and activities, and their geographic alignment with climate impacts. Proposals most often targeted river and riparian ecosystems, fish, and birds. Attention on amphibians and invertebrates was disproportionately low relative to their climate vulnerability. Proposals commonly included efforts to restore previous structures and functions, while relatively few described facilitating change (e.g., supporting future‐adapted species). Proposal density was highest along the Atlantic and Pacific coasts, geographically aligned with non‐profit density and public opinion on climate change. There was no geographic alignment between exposure and proposed responses to five of six climate threats (warming, aridity, wildfire, inland flooding, sea level rise). Our findings identify gaps in adaptation attention, and can enhance strategic resource allocation, targeted capacity building, and adaptation outcomes for conservation.

A REVIEW OF MORTALITY IN TENTACLED SNAKES (ERPETON TENTACULATUM) IN A MULTI-INSTITUTION ZOOLOGICAL COLLECTION BETWEEN 1966 AND 2017.

The tentacled snake (Erpeton tentaculatum) is a viviparous aquatic snake that is a desirable species to exhibit in zoological collections because of its unique appearance and feeding strategies. Despite its presence in zoo collections over the past 50 yr, a comprehensive review of mortality and morbidity in the species has not been published. This study retrospectively reviewed 125 pathology reports from tentacled snakes in a multi-institution zoological collection in New York (The Wildlife Conservation Society's Bronx and Central Park zoos) between 1966 and 2017. Just over half of the deaths were due to infectious disease (n = 67; 53.6%), and of these, over half (n = 40; 59.7%) were due to fungal dermatitis. Fungal histomorphology was consistent with Paranannizziopsis spp. in most cases. Death due to bacterial infection was also relatively common (n = 21; 16.8%), and one-third had intralesional bacilli consistent with Mycobacterium spp. (n = 7; 5.6%). The most common comorbidities included gastrointestinal parasitism (n = 44; 35.2%), renal pathology (n = 31; 24.8%), and lipid accumulation of hepatocytes (n = 13; 10.4%). This retrospective review suggests that managing infectious diseases plays a role in the long-term care and survival of captive tentacled snakes.

Beyond Sea Turtles: Fusarium keratoplasticum in Eggshells of Podocnemis unifilis, a Threatened Amazonian Freshwater Turtle.

The endangered yellow-spotted river turtle (Podocnemis unifilis) has experienced a dramatic population decline in the Ecuadorian Amazonia, mainly due to overexploitation of its eggs. To reverse this trend, the Wildlife Conservation Society has developed a head-start program in Yasuní National Park since 2008, but the potential risk that microbes associated with its eggs might represent for hatching success has not been evaluated yet. Members of the Fusarium solani species complex (FSSC) are involved in egg failure in sea turtles under natural and hatchery conditions, but their role in infecting the eggs of P. unifilis is unknown. In this study, we collected eggshells of P. unifilis and obtained 50 fungal and bacterial isolates. Some potentially pathogenic fungi of the genera Fusarium, Penicillium and Rhizopus were identified based on molecular data. Most importantly, the sea turtle pathogenic species F. keratoplasticum not only was present, but it was the most frequently found. Conversely, we have also isolated other microorganisms, such as Pseudomonas or Phoma-like species, producing a wide spectrum of antifungal compounds that may have a protective role against fungal diseases. Our survey provides useful information on potential pathogens found in P. unifilis eggshells, upon which the success of conservation programs may depend.

A RETROSPECTIVE ANALYSIS OF AMOEBIASIS IN REPTILES IN A ZOOLOGICAL INSTITUTION.

Amoebiasis is a significant protozoal disease of reptiles causing nonspecific clinical signs including diarrhea, anorexia, and lethargy. It frequently results in acute death. Investigation of the pathophysiology of amoebiasis in reptiles has been hampered by the inability to accurately identify amoeba to the species level using conventional techniques. This study reviewed reptile medical records from the Wildlife Conservation Society's archives from 1998 to 2017. Amoebae were identified histologically in 54 cases in 31 different species. Of these, amoebiasis was the cause of death in 32 (18 chelonians, 7 lizards, and 7 snakes), a significant co-morbidity in 14 (six chelonians, two lizards, and six snakes), and seen incidentally in eight cases (one chelonian, six lizards, and one snake). Relocation from one enclosure to another was also evaluated and 65% of cases had been moved within 180 days of death (median 46 days). Frozen tissue samples from 19 of these cases were tested via an Entamoeba (genus-specific) polymerase chain reaction (PCR) assay. PCR products were sequenced and Entamoeba species were identified. Six individuals were positive for Entamoeba invadens (three chelonians, two snakes, one lizard), two for Entamoeba ranarum (both snakes), and one for Entamoeba terrapinae (chelonian); the other 10 cases were negative via PCR. Entamoeba ranarum has typically been considered a disease of amphibians with only one report of disease in a snake. Entamoeba terrapinae has only been reported without associated disease in chelonians. These results suggest that amoebiasis is a complicated and nuanced disease of reptiles, and warrants additional study.

SARCOCYSTOSIS IN A CAPTIVE FLOCK OF THICK-BILLED PARROTS (RHYNCHOPSITTA PACHYRHYNCHA) FROM 2005 TO 2016: MORBIDITY, MORTALITY, DIAGNOSTICS, AND MANAGEMENT STRATEGIES

Sarcocystosis was diagnosed in a captive flock of thick-billed parrots (Rhynchopsitta pachyrhyncha) at the Wildlife Conservation Society's Queens Zoo. Since the index case in 2005, 45% of mortalities in birds over 30 days of age were due to sarcocystosis. Sarcocystis falcatula was repeatedly identified as the causative agent. The disease predominantly affected younger adult parrots. Administration of antiparasitic medications prior to development of respiratory signs prolonged life in infected birds, but disease was fatal until utilization of a three-drug combination (pyrimethamine, trimethoprim-sulfamethoxazole, and ponazuril). This protocol may require in excess of 6 mo of therapy to achieve clinical resolution of active disease. Plasma creatine kinase activity was found to be the most useful test in diagnosing infection and monitoring response to therapy. Polymerase chain reaction (PCR) for apicomplexan organisms on antemortem whole blood, blood smears, or dried blood spots helped confirm suspected cases, but due to the poor sensitivity was sometimes misleading when assessing response to therapy or resolution of clinical disease. Preventive measures, focusing on exclusion and removal of Virginia opossums (Didelphis virginiana) from zoo grounds failed to curtail the occurrence of sarcocystosis in the flock. Other preventative steps, such as modification of feeding stations to exclude potential arthropod paratenic hosts and prophylaxis trials with diclazuril, appeared to successfully mitigate new infections. Given the diagnostic and therapeutic challenges, prevention of exposure to S. falcatula is essential to ex-situ conservation efforts for thick-billed parrots.

Automated location invariant animal detection in camera trap images using publicly available data sources.

A time‐consuming challenge faced by camera trap practitioners is the extraction of meaningful data from images to inform ecological management. An increasingly popular solution is automated image classification software. However, most solutions are not sufficiently robust to be deployed on a large scale due to lack of location invariance when transferring models between sites. This prevents optimal use of ecological data resulting in significant expenditure of time and resources to annotate and retrain deep learning models.We present a method ecologists can use to develop optimized location invariant camera trap object detectors by (a) evaluating publicly available image datasets characterized by high intradataset variability in training deep learning models for camera trap object detection and (b) using small subsets of camera trap images to optimize models for high accuracy domain‐specific applications.We collected and annotated three datasets of images of striped hyena, rhinoceros, and pigs, from the image‐sharing websites FlickR and iNaturalist (FiN), to train three object detection models. We compared the performance of these models to that of three models trained on the Wildlife Conservation Society and Camera CATalogue datasets, when tested on out‐of‐sample Snapshot Serengeti datasets. We then increased FiN model robustness by infusing small subsets of camera trap images into training.In all experiments, the mean Average Precision (mAP) of the FiN trained models was significantly higher (82.33%–88.59%) than that achieved by the models trained only on camera trap datasets (38.5%–66.74%). Infusion further improved mAP by 1.78%–32.08%.Ecologists can use FiN images for training deep learning object detection solutions for camera trap image processing to develop location invariant, robust, out‐of‐the‐box software. Models can be further optimized by infusion of 5%–10% camera trap images into training data. This would allow AI technologies to be deployed on a large scale in ecological applications. Datasets and code related to this study are open source and available on this repository: https://doi.org/10.5061/dryad.1c59zw3tx.

Resource Development and Market Value for Non-wood Forest Products of the Banyang-Mbo Sanctuary of Nguti, Cameroon

The research begins with a brief history of the Banyang-Mbo Sanctuary (BMS) of Nguti, its demographic and geographic dispersion. Next, we aim to identify and analyze the various non-timber forest products, which range from plants, animals, birds and marine species.
 With the aid of write-ups from the Wildlife Conservation Society (WCS) Cameroon, the spatial distribution of these products, vis-à-vis their proximity to surrounded villages is presented. Effort is equally made to know the activities of the villages and other environmental factors that affect the growth and existence of these products. Three objectives and three hypotheses were formulated to give direction to the study. Convenient and purposive sampling techniques were used in the study with the help of questionnaires for data gathering. The population of the study comprised 141 households in Nguti vicinity and a sample size of 105 respondents obtained with the use of Yaro Yamen’s formula. The statistical tools used for data analysis were frequency, mean and tables of percentages to organize the data collected. The instrument was validated by three experts and reliability justified by a coefficient. The study recommended that education on the development of non-wood forest resources should be practically oriented and existing markets should be sustained while new ones be sought for the sales of the final products.

Drivers of deforestation and degradation for 28 tropical conservation landscapes.

Analysing the drivers of deforestation and forest degradation in conservation landscapes can provide crucial information for conservation management. While rates of forest loss can be measured through remote sensing, on the ground information is needed to confirm the commodities and actors behind deforestation. We administered a questionnaire to Wildlife Conservation Society's landscape managers to assess the deforestation drivers in 28 tropical conservation landscapes. Commercial and subsistence agriculture were the main drivers of deforestation, followed by settlement expansion and infrastructure development. Rice, rubber, cassava and maize were the crops most frequently cited as drivers of deforestation in these emblematic conservation landscapes. Landscape managers expected deforestation trends to continue at similar or greater magnitude in the future, calling for urgent measures to mitigate these trends.

Husbandry, morbidity, and mortality of slender‐tailed cloud rats (Phleomys pallidus)

The Wildlife Conservation Society's Bronx Zoo has been housing and breeding slender-tailed cloud rats (Phleomys pallidus) since 1985. Records of 82 animals from 1985 to 2013 were reviewed for this study. The animals were kept successfully in small family groups with a single adult male, multiple adult females, and their offspring. Sexual maturity was noted at approximately 2 years of age and gestation length ranged from 52 to 55 days. Animals were fed a diet including a complete commercial pelleted feed, mixed greens, carrot or yam, mixed hard nuts, and locally sourced browse. Medical conditions requiring treatment in neonates were often fatal whereas most medical conditions in adults were survivable. The most common cause of morbidity and mortality in neonates was maternal neglect or trauma (42%, 5/12 antemortem problems; cause of death in 32%, 8/25). The most significant problems in adults were cryptococcal pneumonia and trauma. Cryptococcus sp. was the cause of death in 11 cases (34%, 11/32) and significant comorbidity in an additional three cases. Treatment with antifungal medications was attempted but was unsuccessful in four cases. Many cases of trauma were treated successfully with conservative management or limited intervention. In four cases, treatment was complicated by extensive self-mutilation after surgical repair of traumatic lesions, which resulted in death or euthanasia. Lymphoplasmacytic thyroiditis was a common postmortem finding in adults (95%, 21/22 for which the thyroid gland was examined histologically). It is unclear if thyroiditis resulted in functional hypothyroidism so the significance of this finding is undetermined.
