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

J Anim Ecol
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.

Bioeconomic modeling of wetlands and waterfowl in Western Canada: Accounting for amenity values [PDF]

This study extends an original bioeconomic model of optimal duck harvest and wetland retention by bringing in amenity values related to the nonmarket (in situ) benefits of waterfowl plsi the ecosystem values of wetlands themselves.

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,

Visual and Olfactory Concealment of Duck Nests: Influence on Nest Site Selection and Success

Human-Wildlife Interactions, 2017
Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is difficult, however, because predators

Balancing Waterfowl Hunting Opportunity and Quality to Recruit, Retain, and Reactivate

Wildlife Society Bulletin, 2020
Waterfowl hunter numbers and waterfowl populations were closely correlated until the past 2 decades when hunter numbers declined despite near‐record breeding population estimates for ducks in North America.

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Milder winters alleviate seasonal challenges for a migratory goose facing Arctic warming

Journal of Animal Ecology, EarlyView.
By combining extensive body mass records with population‐wide migration counts spanning several decades, this study uncovers long‐term improvements in body condition associated with progressively milder winters, alongside earlier spring departure in an Arctic migrant, highlighting the importance of the full annual cycle in determining species ...
