Summary: Understanding population mixing and movements is crucial for the conservation of long-distance migrating bird species. In this study, we investigated the genetic structure and migration patterns of the declining North American Black Tern using genetic samples and individual tracking data. Our results revealed weak genetic structure and the shared use of nonbreeding areas between different breeding populations. This study provides important insights into the population genetics and migration of North American Black Terns.

Summary: This study utilized whole-genome sequencing data to characterize genomic variation in populations of six Ethiopian Highlands forest bird species separated by a lowland biogeographic barrier, the Great Rift Valley (GRV). It was found that the GRV acts as a substantial biogeographic barrier even in highly dispersive species like birds, with species' dispersal ability negatively correlated with levels of population differentiation.

Summary: The study showed that in wild populations of long-lived species, immigrants have lower fitness than residents, with fewer breeding attempts, fledglings, breeding success, and recruits. This may be due to asymmetric limiting resources and the competitive ability of dispersers vs. non-dispersers, supporting female-biased dispersal in birds.

Summary: Research on seed-dispersal mutualisms has shown that the abundance of fruit resources has a positive effect on the degree of frugivory and body condition of frugivorous birds. Consideration of trait matching improves predictions of diet type and body condition, while considering resource provisioning did not enhance explanatory power. Strong and sex-dependent effects of fruit resources on body condition suggest that they may impact the timing and success of reproduction.

Summary: The phenomenon of selective abortion, or selective maturation, in plants can have different effects on fruit traits depending on the dispersal mechanism, as shown in the study of bird-dispersed elderberry. While flower-removed trees had higher fruit sets, there was no increase in the number of seeds per fruit, and the control group did not produce larger fruits. This suggests that the impact of selective maturation on fruit traits may vary among species with different dispersal mechanisms.

Summary: Aquaculture of New Zealand's green-lipped mussel heavily relies on the wild mussel spat supply from Ninety Mile Beach in northern New Zealand. This study used a biophysical model to simulate the dispersal process of mussel larvae and identified primary settlement areas and potential source populations. The results revealed limited larval exchange between two geographic regions in northern New Zealand, with most spat collected at Ninety Mile Beach originating from neighboring mussel beds, particularly those at Ahipara. These findings provide important information for monitoring and protecting the key source populations and ensuring the sustainability of the mussel aquaculture industry in New Zealand.

Summary: The study reveals that the Richard's Pipits in southwestern Europe are true migrants originating from the western edge of their known breeding range, making a remarkable 6,000 km journey from Central Asia across Eurasia. Climatic niche modeling using citizen-science bird data suggests an increase in winter niche suitability in southwestern Europe, potentially leading to increased winter survival and successful return journey of autumn vagrants. This illustrates the underestimated role of vagrancy in the emergence of new migratory routes and adaptation to global change in migratory birds, marking one of the few documented contemporary changes in migration route and the first longitudinal shift in a long-distance migratory bird.

Summary: Research on grey wolf dispersal patterns has shown high variability and is influenced by individual, social, and environmental factors, with human-caused mortality, population density, and interactions with humans impacting dispersal. Methodological issues have been identified that hinder obtaining robust estimates of dispersal parameters and patterns. Reporting results and potential factors affecting wolf dispersal more transparently could significantly benefit wolf biology and management understanding.

Summary: The ability of plants to find tolerable climatic ranges through seed dispersal varies greatly depending on their life-history traits and habitat characteristics. A systematic review on seed dispersal mechanisms was conducted to understand plant seed movements in changing environments. The review found that the majority of studies were conducted in Spain, Brazil, and the USA, while there was limited data from megadiverse countries and Africa. The effects of land use changes, habitat degradation/disturbances, climate, and extreme weather conditions had the most significant impact on seed dispersal mechanisms and agents.

Summary: Understanding the larval ecology of horseshoe crabs is crucial for their management. This study found that early-stage juvenile horseshoe crabs can detect and respond to chemical cues from suitable nursery habitats. They showed a preference for seagrass cues, but avoided cues from mangroves and invasive saltmarsh cordgrass. Preserving and restoring seagrass beds should be a priority for conserving horseshoe crab populations.

Summary: In long-lived species, successful conservation translocations depend on survival and site fidelity during the establishment phase, with concurrent management actions in threatened populations potentially influencing responses. This study compared short-term survival and electrocution rates in translocated and wild-reared juvenile Spanish imperial eagles before and after implementing conservation actions, finding similar survival rates but higher electrocution rates in early dispersal periods. Implementing anti-electrocution measures reduced mortality, but the relative contribution of electrocution as the main cause of death remained consistent between translocated and wild-reared birds.

Summary: LED street lights have shown to reduce the total number of insects captured in light traps across a wide range of families, with Coleoptera and Lepidoptera being the most sensitive groups. The reduced attraction to LED lights is attributed to the lower amount of short-wavelength light emitted and lower light intensity. The widespread use of LED lights as a cost-saving measure for outdoor lighting is expected to further decrease the negative impacts of artificial light attraction on ecosystems.

Summary: The study analyzed blood plasma chemistry parameters of Short-toed Snake Eagles captured in southern Spain, finding that most values did not differ between age classes and sexes. Differences in parameters associated with nutritional condition between captive and wild populations were identified, with a stronger relationship found between urea levels and hatching dates. The results highlight the importance of obtaining blood chemistry reference values from wild populations and how these parameters can complement traditional data collected when handling birds in the field.

Summary: Conservation Biology was established as a tool for managing biodiversity and ecosystems, but the lack of consensus among researchers on which species and spaces to protect and how to preserve ecosystem services is affecting its effectiveness. Environmental thinking, influenced by schools of thought like land ethics and deep ecology, has caused a separation between humans and nature. Overcoming this dichotomy is essential for protecting human-nature habitats.

Summary: This study assessed the potential impact of road networks on the distribution of brown bears in Cantabrian population in Spain. The results showed that road networks had little influence on the distance of bear locations to roads, except for females with yearlings during the denning season. Road networks also had almost no effect on brown bear habitat suitability, possibly due to the majority of roads being located in unsuitable bear habitats. Compared to previous studies conducted in North America, the findings suggest a different response of Eurasian brown bears to roads.

Summary: Birds of prey are often reintroduced using the hacking technique, which involves transferring nestlings to captivity and providing them with ad libitum feeding. A study on reintroduced White-tailed Eagles in Scotland found significant changes in blood chemistry parameters during captivity, indicating improved health status. The provision of ad libitum food was associated with decreased values of urea and uric acid, suggesting reduced nutritional stress. Despite losing body mass before release, the hacked eagles showed improved flight performance, indicating that hacking improves the health and nutritional status of reintroduced birds.

Summary: Avian electrocutions are a significant global conservation issue, causing power outages in Iran. The majority of these outages are due to distribution voltages and grounded concrete pylons with grounded steel crossarms. Components such as insulators, fused cutouts, and transformers are commonly involved in avian-caused outages. Retrofitting power line components to reduce avian contacts would improve wildlife conservation efforts and electrical system reliability.
