Summary: This study examines the adoption of cocoa agroforestry by smallholder farmers near the Tai National Park in Cote d'Ivoire. Results show that most farmers use agroforestry practices, and some are adopting improved agroforestry techniques. Factors influencing cocoa agroforestry adoption include gender, length of residency, number of cultivated cash crops, and incidence of black pod attacks. These findings have important implications for promoting sustainable agriculture practices and biodiversity conservation.

Summary: The attitudes of community members living around protected areas, specifically Kibale National Park in Uganda, are crucial for effective conservation strategies. By implementing sustainable human-wildlife conflict mitigation strategies, such as digging trenches, installing beehive fences, planting tea, and growing garlic, it is possible to improve relationships between communities and wildlife while reducing crop destruction. Results showed a positive correlation between participation in the project and perceived benefits of living near the park, as well as improved attitudes towards the Uganda Wildlife Authority. This research will inform future conservation initiatives in similar areas where human-animal conflicts occur.

Summary: Natural regeneration in forest management is considered a desirable alternative to reforestation, but there are uncertainties in the natural regeneration processes, especially seed dispersal by wind. This study reviews the mechanisms and applications of seed dispersal models and suggests prospects for improving the predictability of natural regeneration. The development of wind-dispersal models has progressed from simple empirical models to more complex mechanistic models, but their application in natural regeneration is limited. Incorporating factors such as seed abscission mechanisms, complex wind environments, collisions during seed flight, and secondary dispersal could enhance seed dispersal models and improve the prediction of its impact on natural regeneration.

Summary: Through non-invasive biomonitoring, we found that 97 chemical pollutants were present in the feces of four primate species in Kibale National Park, Uganda (chimpanzees, olive baboons, red colobus, and red-tailed monkeys), and they were positively associated with fecal hormone metabolites of cortisol and estradiol. The results indicated that organochlorine pesticides and organophosphate esters were positively correlated with cortisol in adult females, and organochlorine pesticides and brominated flame retardants were positively correlated with cortisol in juveniles. These findings suggest that cumulative pesticides and flame retardants can disrupt endocrine function in these primate populations, which may have implications for their development, metabolism, and reproduction. Additionally, our study demonstrates the importance of feces as a non-invasive matrix for examining pollutant-hormone associations in wild primates and other critical wildlife populations.

Summary: Data on space-use patterns are crucial for understanding species ecology and conservation efforts. This study focuses on home range estimates for the Buraiga chimpanzees living in the largest remaining population fragment in Uganda. The analysis reveals that the home range of these chimpanzees covers an area of 15.77 km(2) (95% KDE) and 24.90 km(2) (100% MCP) and overlaps with community-managed land. Additionally, the study finds that the chimpanzees use a larger area during dry season months compared to rainy season months.

Summary: Restoration has become a global priority, with initiatives such as the UN Decade on Ecosystem Restoration. Monitoring vegetation recovery using NDVI and EVI showed non-linear patterns in forest regeneration, with an initial increase in both indices indicating successful onset of forest recovery. Differentiation between primary forests and regenerating forests was possible based on unique combinations of low mean and seasonal variation in EVI.

Summary: Strontium isotope ratios can be used to track changes in an animal's mobility throughout its life and predict sex-biases in dispersal patterns. Different methodological approaches have been introduced to differentiate between 'local' and 'non-local' individuals, with tooth-to-bone offsets reliably indicating sex-biases in dispersal for primates with small home ranges. Overall, tooth-to-environment offsets yield the most reliable predictions of species' sex-biases in dispersal.

Summary: Crop loss caused by wildlife, particularly elephants, poses a threat to livelihoods and conservation efforts in protected areas in Africa and Asia. Low-cost elephant barriers have been successful in savannas but have not been extensively tested in isolated forest parks. This study evaluates the effectiveness of deep trenches dug by farmers near Kibale National Park, Uganda, in preventing crop damage by elephants. The results show that while trenches can deter elephants, the quality of the trenches and the presence of palatable crops influence the likelihood of damage.

Summary: This study aimed to explore the biological processes related to tree height allometry of Black pine and develop a generalized mixed-effects model for tree height prediction. The proposed model, with three additional basic covariates and two random parameters, explained almost 96% of the height variance. The results showed that while competition and site-connected variables affected total height, crown base height was a significant factor in height expression.

Summary: Browsing by wild ungulates has significant effects on forest structure and composition. In the Swiss National Park, the high density of red deer, ibex, and chamois is attributed to strict protection and absence of large predators. Analysis of count data from 1991 to 2021 reveals an increase in saplings and young trees despite the presence of wild ungulates. Browsing probability is highest for larch saplings at a height of 10-40 cm and increases with elevation.

Summary: Anthropogenic disturbances, such as hunting and logging, are impacting tree communities in tropical forests, with forests near human settlements showing richer, more heterogeneous, and dynamic species compositions. Once-logged forests have the highest stem density and intermediate species richness, with an increase in shade-bearing species over time. Tree species spatial turnover and tree recruitment are greatly affected by proximity to human settlements.

Summary: Resource availability is important for female reproductive success, and the timing of reproduction can affect maternal and infant survival. In this study, the researchers examined data on births, conceptions, mating seasonality, and interbirth intervals in vervet monkeys living near Lake Nabugabo, Uganda. They found that births occurred year-round but were moderately seasonal, and there was no difference in survival for infants born within or outside of birth peaks. The researchers also found that fruit availability and feeding habits did not vary seasonally, and interbirth intervals were shorter in higher-ranking females. These findings suggest that habitat differences and latitudinally-variable factors may influence the breeding seasonality and interbirth intervals in the Nabugabo vervet population.

Summary: Rank has a significant impact on health and fitness within social animal groups. In the social networks of Astatotilapia burtoni, dominant males frequently chase subordinate males and females, while display behaviors mainly occur among highly ranked males. Territory loss is associated with a decrease in aggression level, while ascending males display elevated aggression prior to territory acquisition.

Summary: Among mammals, the order Primates stands out for its high taxonomic richness and the diversity of arboreal, semiterrestrial, or terrestrial taxa. The transition from arboreality to terrestriality in primates is influenced by ecological factors and species-specific traits. As humans modify habitats and climate change occurs, species inhabiting hot, sparsely canopied environments and with more generalized diets are more likely to shift towards increased ground use.

Summary: In Africa, protected forests in densely populated areas experience intense human-wildlife conflict. A study in Kibale National Park, Uganda, showed that baboons and elephants were responsible for most crop raiding incidents. While the financial loss caused by both species did not differ significantly, elephants were perceived as more damaging. Guarding and trenches were identified as the most effective deterrent strategies for baboons and elephants, respectively. Factors such as distance from the park and household income influenced the likelihood of crop raiding, and households headed by women or older adults were found to be more vulnerable.

Summary: During the dawn chorus, many songbirds sing intensely in the early morning. In this study, it was observed that male Adelaide's warblers warm up their voices during the dawn chorus, resulting in increased vocal performance. The primary driver of improved performance was a reduction in the duration of the silent gap between notes. Singing at a high rate during the dawn chorus was found to increase performance in two of the three performance measures.

Summary: Declines in arthropod abundance and diversity have been observed in Kibale National Park, Uganda over the past four decades, particularly in the logged forest areas. Changes in arthropod communities were found to be influenced by multiple factors, including temperature increase, mammal species shifts, and changes in forest structure. Additionally, alterations in the landscape surrounding the park, such as population growth and agricultural intensification, may also contribute to the observed declines. Therefore, long-term multi-disciplinary efforts are necessary for effective conservation planning.

Summary: This study analyzed the effects of site and climate on the self-thinning line in Scots pine forests in Europe. The results showed that species tolerance, temperature, and precipitation influenced the slope of the self-thinning line. In terms of the intercept, latitude and radiation had compensating effects. Time did not show significant trends in the self-thinning line. The study highlights the need to adapt management strategies and models based on self-thinning to different latitudes. Climate change has not yet significantly impacted the self-thinning trajectory, but a continuous rise in temperature and high precipitation may accelerate the self-thinning process and result in increased biomass accumulation.

Summary: Secondary forests play a crucial role in ecosystem dynamics and biodiversity recovery. This study investigated the mechanisms underlying secondary succession in a restored secondary forest and found that deciduous tree species transition from diversity accumulators to repellents as they progress through different life history stages, while evergreen tree species can act as accumulators or remain neutral. The study also revealed the effects of density dependence on the mortality and regeneration of different tree species, and highlighted the importance of early-arriving tree species in facilitating the establishment and diversity of late-arriving counterparts.

Summary: Regeneration failures in the closed-crown boreal forest, resulting in the creation of open lichen woodlands, can be restored through clear-cutting, scarification, and natural seeding. Clear-cutting combined with scarification promotes seedling establishment, and scarification creates suitable microsites for germination. Seedling growth in lichen woodlands is higher when logging and scarification are combined, but lower compared to feather moss stands. Afforestation through natural seeding following scarification could be a cost-effective option for restoring lichen woodlands.
