The classical theory of island biogeography , which predicts species richness using area and isolation, has been expanded to include contributions from marine subsidies, i.e. subsidized (SIB) . We tested the effects subsidies on diversity population density productive temperate islands, evaluating SIB predictions previously untested at comparable scales subsidy levels. found that terrestrial breeding bird communities 91 small islands (approx. 0.0001–3 km 2 ) along Central Coast British...
Abstract Although marine subsidies often enrich terrestrial ecosystems, their influence is known to be context‐dependent. Additionally, the multitrophic impact of has not been traced through food webs across physically diverse islands. Here, we test predictions about how island characteristics can affect enrichment web constituents and nutrients flow webs. To evaluate trace webs, used stable isotopes soil, flora, fauna ( n = 4752 samples) collected from 97 islands in British Columbia,...
Abstract Background To effectively conserve migratory species, the entire range encompassed by their annual life cycle needs to be considered. Most research on Nearctic-Neotropical birds has focused breeding grounds resulting in a general lack of knowledge regarding wintering and periods. The Canada Warbler ( Cardellina canadensis ) declined 71% from 1970 2012, at rate 2.9% per year, is listed as Threatened Canada. As with most migrants, conservation efforts outside are limited poor...
Abstract Aim Species distributions across islands are shaped by dispersal limitations, environmental filters and biotic interactions but the relative influence of each these processes has rarely been assessed. Here, we examine contributions island characteristics, marine subsidies, species traits, on avian community composition. Location Central Coast region British Columbia, Canada. Taxon Terrestrial breeding birds. Methods We observed 3610 individuals 32 bird 89 that spanned multiple...
This study establishes an altiudinal gradient, spanning from the highland Andes (2400 m) to lowland Amazon, as a productive region for of bird pollination in Southeastern Peru. The 'Manú Gradient' has rich history ornithological research, published data and resources which lay groundwork analyses plant-bird interactions. In this preliminary expedition we documented 44 plants exhibting aspects syndrome, made field observations hummingbird visits at three sites Manú Gradient: 2800 m...

We developed aging criteria for 7 species of manakins (Pipridae) from the Manu Biosphere Reserve, Peru, based on patterns plumage maturation and wing-feather replacement following their preformative molt, summarize information morphological characteristics. Each underwent a partial which could be identified using presence molt limits in greater coverts. Some male Band-tailed Manakin (Pipra fasciicauda), Round-tailed (Ceratopipra chloromeros), Cerulean-capped (Lepidothrix coeruleocapilla),...
Abstract Species richness and abundance of hosts parasites are often not perfectly correlated. This may be caused by higher parasite than host extinction rates or population declines, but lower discovery effort has also been suggested. The Mexican free‐tailed bat Tadarida brasiliensis is one the most common widespread vertebrates in Americas to ectoparasite Primicimex cavernis , for which only 14 literature records from six sites worldwide exist. Here, we confirm a much smaller range. Two...
In the past, monitoring hunting behavior has been limited to self-reported numbers. However, ability of autonomous recording units monitor soundscapes may make them suitable for assessing spatio-temporal shooting patterns. Our goal this project was find out if it is possible use acoustic track human activity, and there were differences in seasonal or daily intensities. We hypothesized that intensity would decrease from September November afternoon till morning due people being less likely go...
