Records of Longevity in Canada Geese [PDF]

open access: yesThe Auk, 1957
Records of Longevity in Canada Geese.-Two records of longevity in Canada Geese (Branta canadensis) were secured from banded birds killed during the 1955 waterfowl hunting season on the Swan Creek Wildlife Experiment Station eight miles northwest of Allegan, in southwestern Michigan.

Using programmable infusion pump in avian species – a validation methodology in geese

open access: yesWildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Does species composition of arctic geese recovered in prairie Canada vary by hunter residency?

open access: yesWildlife Society Bulletin, 2011
Estimates of goose harvest by the National Harvest Survey (NHS) in Canada are based on the assumption that species composition of harvest by non‐Canadians that hunt in Canada is equivalent to that of Canadians.

Exploring sources of uncertainty in the estimate of waterfowl harvest in the United Kingdom

open access: yesWildlife Biology, EarlyView.
There is an urgent need to gather data on harvest rates of waterbirds in Europe to assess the sustainability of hunting. Estimates of total waterbird harvest in the United Kingdom (UK) and the relative harvest of different huntable species come from two separate surveys, the Value of Shooting (PACEC 2014) and National Gamebag Census (NGC), and these ...

Ten years of resident Canada goose damage management in a New Jersey tidal freshwater wetland

open access: yesWildlife Society Bulletin, 2014
Intensive grazing by Atlantic Flyway Resident Population Canada geese (Branta canadensis) has been shown to dramatically reduce wild rice (Zizania aquatica) abundance in tidal freshwater marshes in the Mid‐Atlantic Region of the United States.

Reduction in biomass of freshwater arctic vegetation by foraging and nesting hyperabundant herbivores shows recovery

open access: yesEcosphere, 2022
Arctic‐nesting geese are specialist herbivores of grasses and sedges (collectively, graminoids). Under moderate grazing pressure, these migratory herbivores can create and maintain arctic grazing lawns with high nutritional content and low aboveground ...

The Vee Formation of Canada Geese [PDF]

open access: yesThe Auk, 1974
THE organized vee formations of geese and other waterfowl have drawn attention from sportsmen and scientists for years. Lissaman and Shollenberger (1970) proposed that birds may fly in a vee to capitalize on upward rising components of the wingtip vortex currents generated by the wings of neighboring birds flying to the front and side.

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

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

open access: yesJournal 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.

Boldness and niche width structure spatial interactions in a natural rodent community

open access: yesJournal of Animal Ecology, EarlyView.
We show that individual behavioural differences (boldness) structure spatial encounter patterns within a natural multi‐species community. By linking personality to space use and interaction structure, our study demonstrates how intraspecific variation can scale up to shape community‐level processes.
