Summary: Successful invasions of non-native plants often rely on establishing mutualistic interactions with native organisms, with animal seed dispersers playing a key role in enhancing the spread of invasive plants. Research found that Eurasian jays favored harvesting acorns from native pedunculate oaks, but also removed almost all offered acorns of the invasive northern red oaks, especially when the two oak species co-occurred.

Summary: Climate and land use changes are affecting bird populations' behavior and flight initiation distance (FID) in response to human approaches. FIDs decrease with increasing temperature and precipitation, indicating reduced foraging success in warm and humid conditions. Factors like latitude, urbanization, and body mass also influence FID trends, suggesting that climate effects on FIDs are mediated by food availability and hierarchical positions in food webs. This study highlights the importance of behavioral responses within food webs in influencing bird populations and communities under global change.

Summary: Studying population ecology and behavior of large raptors with life-history traits involving high survival and low reproductive output can be challenging. GPS-telemetry has proven valuable in studying aspects such as age of first territory settlement (AFTS). Using GPS-records from tagged Golden Eagles, we estimated AFTS and found a range of ages, including much younger settlement ages than previously documented. Our results suggest that GPS-data can provide accurate estimations of AFTS, including early settlement ages not consistently recorded by other methods.

Summary: Honeybees form mating aggregations with many male drones from nearby colonies. This study investigated the factors limiting dispersal distance by measuring the body size and age of drones at congregation sites. It also examined the relationship between these factors and flight abilities using a flight mill. The results suggest that body size and age of drones may impact the structure and characteristics of mating congregations through dispersal.

Summary: In order to understand animal ecology, mitigate threats, and protect species effectively, it is important to study how different age and sex groups utilize space over time. Little is known about the movement patterns of immature animals during their dispersal period. This study focuses on the movement behavior of immature Andean condors and finds that their movement patterns differ according to age, sex, and season. The findings highlight the importance of considering the movements of immature individuals in conservation strategies.

Summary: During migration, birds need to find suitable stopover habitats with resources to rest and refuel. Long-distance migrants often encounter inhospitable areas with limited food and safety. In response, they may retreat or detour in search of better habitat. Our study tracked the behavior of migratory birds departing from edge habitat along the northern Gulf of Mexico coast, showing that individual decisions can affect habitat use and migration strategies.

Summary: Endozoochory by waterfowl is important for a broad range of angiosperms, most of which lack a fleshy fruit. This dispersal function contributes to the formation and maintenance of plant communities and may allow range shifts for plant species under global change. However, our current understanding of what seed or plant traits are important for this dispersal mechanism, and how they relate to variation in waterbird traits, is extremely limited.

Summary: The study of Muskellunge behavior in two lakes in Iowa revealed differences in depth and movement patterns across seasons and behaviors, but similarities in escapement and natural mortality rates. Muskellunge in Brushy Creek showed the highest escapement rate, which may be associated with the increasing escapement probability with rising reservoir water levels.

Summary: The study found that the banana weevil quickly detected viable inoculum of Foc on external teguments and in the digestive tract after contact with infected pseudostems. External inoculum was higher than internal inoculum, but both decreased exponentially within 50 hours after contact with an infected source. Despite this, weevils remained infested for up to 2-3 days, allowing for potential inoculum dispersal.

Summary: In this study, a hybrid process-based/statistical modeling approach was used to quantify the effect of landscape composition on banana leaf streak disease (BLSD) epidemiology. The proportion of hedgerows in a 200-m-radius buffer zone was found to act as a constraint against BLSD spreading. On the other hand, the proportion of managed-banana-plants in a 1,000-m-radius buffer zone was negatively correlated with the landscape effect.

Summary: Different reproductive modes have varying costs and benefits depending on ecological contexts. In this study, the factors influencing the frequency of sex in the mayfly A. muticus were investigated. Results showed that mate limitation had a significant impact on sex ratios, while community diversity and altitude did not. Even when females have the ability for parthenogenesis, they still predominantly reproduce sexually, indicating the benefits of sex outweigh its costs in most situations. Mate limitation may contribute to the prevalence of parthenogenesis in mayflies.

Summary: Agroforestry systems (AFS) are becoming increasingly important in cocoa producing countries. However, the competition effects within these multispecific agricultural systems have not been thoroughly understood, making it difficult to design spatial patterns and manage cocoa AFS (cAFS) with minimal competition. In this study, we analyzed the influence of neighboring tree community composition on cocoa tree pod production in 48 cAFS plots in Central Cameroon. We found significant intra-specific competition within the cocoa tree populations and a negative effect of associated fruit trees on pod production, particularly when positioned 6-11 m away from cocoa trees. Palm trees, on the other hand, had a positive effect on pod production. Our results highlight the complex interactions and resource limitations that affect cocoa production in cAFS.
