Cross-continental comparison of parasite communities in a wide-ranging carnivore suggests associations with prey diversity and host density

Astrid Stronen, Barbara Molnar, Paolo Ciucci, Chris Darimont, Lorenza Grottoli, Paul Paquet, Tim Sallows, Judit Smits & Heather Bryan
Parasites are integral to ecosystem functioning yet often overlooked. Improved understanding of host-parasite associations is important, particularly for wide-ranging species for which host range shifts and climate change could alter host-parasite interactions and their effects on ecosystem function. Among the most widely distributed mammals with diverse diets, grey wolves (Canis lupus) host parasites that are transmitted among canids and via prey species. Grey wolf-parasite associations may therefore influence the population dynamics and ecological functions of...

Do phylogeny and habitat influence admixture among four North American chickadee (family: Paridae) species

Brendan Graham, Gazeley Ian, Otter Ken & Burg Theresa
Hybridization is an important aspect of speciation, yet questions remain about the ecological and environmental factors that influence hybridization among wild populations. We used microsatellite genotyping data and collected land cover and environmental data for four North American chickadee species: black-capped Poecile atricapillus, mountain P. gambeli, chestnut-backed P. rufescens and boreal P. hudsonicus chickadees. Combining these datasets, we sought to examine whether there is evidence of admixture between four widely distributed North American chickadee species;...

Data from: Network ecology in dynamic landscapes

Marie-Josee Fortin, Mark Dale & Chris Brimacombe
Network ecology is an emerging field that allows researchers to conceptualize and analyze ecological networks and their dynamics. Here, we focus on the dynamics of ecological networks in response to environmental changes. Specifically, we formalize how network topologies constrain the dynamics of ecological systems into a unifying framework in network ecology that we refer to as the “ecological network dynamics framework”. This framework stresses that the interplay between species interaction networks and the spatial layout...

Can diet composition estimates using stable isotope analysis of feathers predict growth and condition in nestling mountain bluebirds (Sialia currucoides)

Aija White & Russell Dawson
Insectivorous birds breeding in seasonal environments provision their dependent young during periods when prey diversity and abundance vary. Consequently, the composition and nutritional value of diets parents feed to their offspring may differ within and among broods, potentially affecting the condition of nestlings. In a population of mountain bluebirds (Sialia currucoides), we used two methods to estimate diet composition for individual nestlings: direct observation of provisioning using video recordings at 5 and 9 days post-hatch,...
