Eelgrass Distribution in the Great Bay Estuary for 2011 [PDF]

open access: yes, 2012
Eelgrass in the Great Bay Estuary declined in both distribution and biomass between 2010 and 2011. In 2011, eelgrass was once again mainly present in the Great Bay itself with limited distribution in Portsmouth Harbor and Little Bay.

Evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese. [PDF]

open access: yesPLoS ONE, 2013
Quantifying spatial patterns of bird nests and nest fate provides insights into processes influencing a species' distribution. At Cape Churchill, Manitoba, Canada, recent declines in breeding Eastern Prairie Population Canada geese (Branta canadensis ...

Almost Seven Decades of Coastal Bird Community Recovery Across Three European Seas

open access: yesGlobal Change Biology, Volume 31, Issue 11, November 2025.
Our study examined long‐term trends in coastal bird communities across three European seas from 1957 to 2024. We found that bird abundance and diversity have increased over time, although these improvements vary among regions and sites. Protected areas—particularly strictly protected ones—play an important role in supporting these recoveries, but ...

Solar Radiation Affects Bird Distributions but Not Elevational Shifts in European Mountains

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim Climate change is driving species towards higher elevations. While local shifts in elevation are well documented, patterns across entire mountain regions are less understood. On a local scale, abiotic factors, such as topography and solar radiation relating to microclimate, affect species distributions and can thus influence the rate of ...

Evolutionary genetics of birds IV rates of protein divergence in waterfowl (Anatidae) [PDF]

open access: yes, 1986
An electrophoretic comparison of proteins in 26 species of waterfowl (Anatidae), representing two major subfamilies and six subfamilial tribes, led to the following major conclusions: (1) the genetic data, analyzed phenetically and cladistically ...

Effects of Goose Herbivory on Littoral Vegetation and Aquatic Macroinvertebrates During Breeding Season

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT During recent decades, increased populations of geese have raised concerns about their potential impact on the abundance and composition of shoreline vegetation through grazing, and how this may affect other organisms relying on the same vegetation for food or refuge.

Bone Mineral Density of Willow Ptarmigan (Lagopus lagopus) as a Potential Taphonomic Factor in Skeletal Part Attrition

open access: yesInternational Journal of Osteoarchaeology, Volume 35, Issue 5, Page 284-294, September/October 2025.
ABSTRACT Agents of taphonomy can bias skeletal parts and the frequency of bones in archaeological sites. An important factor to consider is the possible effect of bone density‐mediated attrition on archaeornithological assemblages. We scanned willow ptarmigan (Lagopus lagopus) specimens using a Lunar iDXA and an enCcore small animal body add‐on to ...
