Larus gull species have proven adaptable to urbanization and due their generalist feeding behaviors, they provide useful opportunities study how urban environments impact foraging behavior host-associated microbiota. We evaluated influenced the microbiome characteristics of breeding herring gulls (Larus argentatus) at three different colonies on east coast United States. Study represented high, medium low degrees urbanization, respectively. At all colonies, frequently foraged landfills in...
Temporal and spatial predictability of food resources are critical to the foraging efficiency central place foragers. While site fidelity is often assessed in this context, route fidelity, or repeated use same path while traveling, temporal aspects habitat have received less attention. We examined how urban, coastal, offshore habitats influenced spatiotemporal patterns herring gulls (Larus argentatus) great black-backed (L. marinus). Since show higher when urban habitats, we predicted that...
The transfer of nutrients between marine and terrestrial systems has important ecological consequences, animal movement is an driver nutrient transfer. Coastal birds forage in environments breed habitats, thus serve as vectors moving from the sea to land. However, urbanization can influence extent which coastal or due availability human subsidies. Establishing a reliable straightforward indicator foraging would be useful for assessing changes use vs. habitats face broader environmental...
Abstract Urban habitats can create empty trophic niche space by providing abundant alternative dietary resources, allowing some generalist species to either shift or expand their niches. Resulting changes size may consequently affect interspecific interactions and competition, although impacts are less clear in peri‐urban systems, where both natural urban resources readily accessible highly mobile species. We combined stable isotope (δ 13 C, δ 15 N, 34 S) data with GPS tracking of two...
Abstract Domestic cats Felis catus have a complex and contentious history. They fill multiple societal roles (e.g. as pest controllers companion animals), which has led to variety of animal welfare, conservation, human health concerns. Popular press articles play an important role in how people learn about key issues surrounding cats, but they may present some more frequently than other issues. We conducted global media content analysis 796 the English‐language from 1990 2018 on related...
The decorator worm Diopatra cuprea , a tube-forming marine polychaete common to intertidal and shallow subtidal waters, modifies habitats it occupies through microreef construction algal gardening. While several studies have demonstrated that tubes are hotspots of biogeochemical activity (i.e., nitrogen sulfur cycling), is still largely unclear whether the tube microbiome differs compositionally from surrounding sediment what distinct functional processes microbiomes may have. To address...
For many species, breeding performance increases through early adulthood followed by declines later in life. Although patterns of age-specific decline have been shown to vary between individuals, the factors that lead this individual variation intensity reproductive senescence are yet be fully understood. We investigated whether early-life social status influenced age-related trends male Canada jays ( Perisoreus canadensis ), year-round residents North America's boreal and sub-alpine...
Florida Scrub-Jays (Aphelocoma coerulescens) are cooperative breeders endemic to Florida's oak scrub. In autumn, cache thousands of acorns and exhibit behaviors that appear balance site selection against food degradation or robbery. However, both experience position within a social dominance hierarchy could affect individual preferences. We examined the preferences birds with differing levels caching at different strata complex hierarchy. Our objective was determine how experience, position,...
Abstract Whether an individual disperses or remains site‐faithful between breeding seasons can have important impacts on fitness and population dynamics. While several studies identified factors influencing the probability of dispersal, consequences dispersal are much less certain, particularly over individual’s lifetime. Here, we use 81 cases (13 paired 55 single dispersals) across yr re‐sighting data from individually marked Canada jays ( Perisoreus canadensis ) at southern edge their...
While delaying natal dispersal can provide short-term benefits for juveniles, lifetime fitness consequences are rarely assessed. Furthermore, competition limited positions on a territory could impose an indirect cost the winner if outcome has negative effects its siblings. We use radio-tracking and 58 years of nesting data in Ontario, Canada to examine sibling expulsion jay (
Temporal variation in food web structure is widespread among highly seasonal environments, such as the Arctic, and driven by changes resource availability. Variation availability can lead to species differences diet composition, isotopic niche width, trophic position (TP) across seasons. Here, we used tissue samples that represent two distinct turnover rates for (liver = shorter term, muscle longer term) from 18 fish three marine mammal investigate (i) TPs within Southampton Island ecosystem...
Our understanding of avian incubation behaviour is primarily derived from species that nest in the temperate conditions spring and summer. This leaves uncertainties about strategies employed by a relatively small number adapted to breed under sub-zero, winter-like conditions. We used in-nest temperature loggers (iButtons) monitor behaviours Canada Jays, cache-reliant, year-round residents boreal sub-alpine environments late winter/early have female-only incubation. Females had high levels...
ABSTRACT For most birds that exhibit delayed dispersal (remaining on the natal territory rather than dispersing to seek a breeding opportunity), siblings appear free stay or leave area. However, in rare cases, delaying is determined via conflict among siblings, with dominant individual remaining territory. We used radio-tracking examine brood reduction, and subsequent juvenile survival, of first-year Canada Jays (Perisoreus canadensis) Algonquin Provincial Park, Ontario, Canada. Soon after...
Habitat preferences in animals are often examined during the breeding period when individuals easier to observe. However, habitat use may change once young become independent and if resource availability shifts with seasonality. While Canada Jays ( Perisoreus canadensis (Linnaeus, 1766)) Algonquin Provincial Park, Ontario, Canada, have been studied for several decades, there is no information on outside of fall late-winter nesting period, where they primarily used conifer forests. Using...
