Abstract Anthropogenic changes in climate and land use are driving migration patterns of birds worldwide. Spatial have been related to long-term temperature trends, but the intrinsic mechanisms by which migratory species adapt environmental change remain largely unexplored. We show that, for a long-lived social species, older with more experience critical innovating new behaviours. Groups containing older, experienced individuals establish overwintering sites closer breeding grounds, leading...
Abstract Animal migration is a global phenomenon, but few studies have examined the substantial within‐ and between‐species variation in distances. We built database of 94 land migrations large mammalian herbivore populations ranging from 10 to 1638 km. how resource availability, spatial scale variability body size affect distance among populations. Resource availability measured as normalised difference vegetation index had strong negative effect, predicting tenfold distances between low‐...
Migrating animals may benefit from social or experiential learning, yet whether and how these learning processes interact change over time to produce observed migration patterns remains unexplored. Using 16 years of satellite-tracking data 105 reintroduced whooping cranes, we reveal an interplay between in timing. Both dramatically improved individuals' abilities dynamically adjust their timing track environmental conditions along the path. However, results revealed ontogenetic shift...
Avian influenza viruses pose a threat to wildlife and livestock health. The emergence of highly pathogenic avian (HPAI) in wild birds poultry North America late 2021 was the first such outbreak since 2015 largest date. Despite its prominence economic impacts, we know relatively little about how HPAI spreads bird populations. In January 2022, captured 43 mallards (Anas platyrhynchos) Tennessee, USA, 11 which were actively infected with HPAI. These confirmed detections H5N1 clade 2.3.4.4b...
Abstract Aim Animal movement is an important determinant of individual survival, population dynamics and ecosystem structure function. Nonetheless, it still unclear how local movements are related to resource availability the spatial arrangement resources. Using resident bird species migratory outside period, we examined distribution resources affects patterns both large terrestrial birds (e.g., raptors, bustards hornbills) waterbirds cranes, storks, ducks, geese flamingos). Location Global....
Long-distance animal movements can increase exposure to diverse parasites, but also reduce infection risk through escape from contaminated habitats or culling of infected individuals. These mechanisms have been demonstrated within and between populations in single-host/single-parasite interactions, how long-distance movement behaviours shape parasite diversity prevalence across host taxa is largely unknown. Using a comparative approach, we analyse the communities 93 migratory, nomadic...
Environmental contamination is widespread and can negatively impact wildlife health. Some contaminants, including heavy metals, have immunosuppressive effects, but prior studies rarely measured disease simultaneously, which limits our understanding of how contaminants pathogens interact to influence Here, we mercury concentrations, influenza infection, antibodies body condition in 749 individuals from 11 species wild ducks overwintering California. We found that the odds infection increased...
Abstract Understanding relationships between infection and wildlife movement patterns is important for predicting pathogen spread, especially multispecies pathogens those that can spread to humans domestic animals, such as avian influenza viruses (AIVs). Although with low pathogenic AIVs generally considered asymptomatic in wild birds, prior work has shown influenza‐infected birds occasionally delay migration and/or reduce local movements relative their uninfected counterparts. However, most...
Interactions between wildlife and livestock can lead to cross‐species disease transmission, which incurs economic costs threatens conservation. Wild waterfowl are natural hosts of avian influenza viruses (AIVs), often abundant near poultry farms, have been linked outbreaks AIVs in poultry. Interspecific seasonal variation movement habitat use means that the risk transmission wild birds inevitably varies across species, space, time. Here, we used GPS telemetry data from 10 species...
Contemporary wildlife disease management is complex because managers need to respond a wide range of stakeholders, multiple uncertainties, and difficult trade-offs that characterize the interconnected challenges today. Despite general acknowledgment these complexities, managing tends be framed as scientific problem, in which major challenge lack knowledge. The multifactorial process decision-making collapsed into endeavor reduce uncertainty. As result, contemporary may oversimplified, rely...
Mobile animals transport nutrients and propagules across habitats, are crucial for the functioning of food webs ecosystem services. Human activities such as urbanization can alter animal movement behavior, including site fidelity resource use. Because many urban areas adjacent to natural sites, mobile might connect habitats. More generally, understanding patterns in help predict how expansion will affect roles highly ecological processes.Here, we examined movements by a seasonally nomadic...
Abstract Aim Populations of cold‐adapted species at the trailing edges geographic ranges are particularly vulnerable to negative effects climate change from combination exposure warm temperatures and high sensitivity heat. Many these predicted decline under future scenarios, but they could persist if can adapt warming climates either physiologically or behaviourally. We aim understand local variation in contemporary habitat use this information identify signs adaptive capacity. focus on...
Background Causes of permanent work disability in the sheet metal industry are not well characterized. Methods Pension records were used to compare causes among workers and U.S. working population. Subgroup analysis examined major worker disability. Results Musculoskeletal disorders (MSDs), circulatory disease, injuries leading (47.2%, 13.7%, 10.9% awards, respectively). Award distribution differed from population ( P < 0.0001); MSDs accounted for higher proportions particularly at spine,...
Understanding the drivers of biodiversity is important for forecasting changes in distribution life on earth. However, most studies are limited by uneven sampling effort, with some regions or taxa better sampled than others. Numerous methods have been developed to account differences but were systematic surveys which all study units using same design and assemblages randomly. Databases compiled from multiple sources, such as literature, often violate these assumptions because they composed...
Abstract Even within a single population, individuals can display striking differences in behavior, with consequences for their survival and fitness. In reintroduced populations, managers often attempt to promote adaptive behaviors by controlling the early life experiences of individuals, but it remains largely unknown whether this training has lasting effects on behavior. We investigated behavior whooping cranes ( Grus americana ) trained migrate using two different methods see migration...
Many migratory bird species have begun shifting their wintering grounds closer to breeding grounds, shortening yearly migration distance through a behavior called shortstopping. While multiple studies investigated possible drivers, it remains unclear why only some populations adopt this behavior. We studied the differential occurrence of shortstopping in two Whooping Cranes (Grus americana): remnant population where juveniles migrate with parents, and reintroduced consisting largely...

Conversion of natural habitats into urban landscapes can expose wildlife to novel pathogens and alter pathogen transmission pathways. Because is difficult quantify for many pathogens, mathematical models paired with field observations help select among competing pathways that might operate in landscapes.
