Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Cumulative effects of piscivorous colonial waterbirds on juvenile salmonids: A multi predator-prey species evaluation.

PLoS ONE, 2022
We investigated the cumulative effects of predation by piscivorous colonial waterbirds on the survival of multiple salmonid (Oncorhynchus spp.) populations listed under the U.S.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Long‐term patterns of breeding range expansion mirror invasion dynamics during recolonisation of a semi‐colonial raptor

Journal of Animal Ecology, EarlyView.
We used a unique long‐term dataset of population recovery in the Osprey Pandion haliaetus to reveal the similarity in spatial patterns underpinning recolonisations and biological invasions. Our findings highlight the importance of rare pioneering movements in driving range expansion, and the value of conservation interventions such as species ...

Behavior of Nannopterum brasilianus (Gmelin, 1789) (Suliformes: Phalacrocoracidae) in an urban park in the municipality of Uberlândia, Minas Gerais State

Biotemas, 2019
The modification of landscapes by anthropic action, mainly due to urbanization, exerts strong pressure on birds. Public parks and other green areas offer favorable conditions for birds in cities throughout the year. Nannopterum brasilianus (Gmelin, 1789)

Habitat heterogeneity influences avian feeding guild composition in urban landscapes: evidence from Bhubaneswar, India

Ecological Processes, 2021
Background Habitat heterogeneity clearly distinguished in terms of availability of food and habitat resources and landscape features (natural or human-modified) play a crucial role in the avian species composition and population structure.

Recovery of Four Commercial Fish Stocks in Lake IJsselmeer (The Netherlands) After Major Fishery Management Interventions

Fisheries Management and Ecology, EarlyView.
ABSTRACT Sustainable management of inland fisheries presents major challenges because it often involves complex and open access systems. Lake IJsselmeer is among the largest freshwater lakes in western Europe and supports active commercial fisheries.

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Fish Exhibit Distinct Fluorochemical and δ15N Isotopic Signatures in the St. Lawrence River Impacted by Municipal Wastewater Effluents

Frontiers in Environmental Science, 2022
We examined the influence of Montreal wastewater treatment plant (WWTP) effluents on two top predators, Walleye (Sander vitreus) and Sauger (Sander canadensis), with a focus on δ15N isotopic signatures and per- and polyfluoroalkyl substances (PFAS ...
