A photographic approach to monitor spatial dynamics and population trends of Arctic Tern colonies in two touristic bird watching spots in the Westfjords, Iceland

Avocetta
This study examines the population dynamics and spatial distribution of Arctic Terns in two tourist sites in Iceland's Westfjords: Vigur Island and Súðavík. In 2023, counts revealed 458 terns in Súðavík and 991 in Vigur. We propose a monitoring approach

Scale choices shape species adaptation predictions: Improving conservation modeling under global change

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
This paper demonstrates how choices on temporal and spatial modeling scales affect our understanding of species adaptation to changing environments, using tiger conservation in Nepal's Bardia National Park as a case study. We provide four novel recommendations for scale‐aware ecological modeling under global change: explicit documentation of scale ...

Estimating waterfowl breeding pair and brood densities using distance sampling with uncrewed aerial systems

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Uncrewed aerial systems (UAS) equipped with thermal cameras are increasingly being used in wildlife research. Here, we explore the use of UAS paired with distance sampling to detect and estimate densities of waterfowl pairs and broods in Wisconsin.

Shortlist Masterplan Wind Ship-based monitoring of seabirds and cetaceans [PDF]

During April 2010 – February 2011, monthly surveys of seabirds and marine mammals were conducted aboard ships engaged in plankton surveys. After many years of little or no effort in far offshore areas of the DCS, this series of surveys provided the first

Winter Survival of Grasses and Legumes in Subarctic Alaska as Related to Latitudinal Adaptation, Pre-Winter Storage of Food Reserves, and Dry-Matter Concentration in Overwintering Tissues [PDF]

, 1993
similar experiments, were to (a) compare winter hardiness in subarctic Alaska of numerous plant species and ecotypes from various latitudinal sources within most species, and (b) seek a better understanding of certain aspects of pre-winter ...

Global Evidence of the Unimodal Response of Ecosystem Respiration to Soil Moisture

Advanced Science, Volume 13, Issue 3, 14 January 2026.
Using global eddy covariance observations and a field experiment, this paper provides compelling evidence for the widespread unimodal relationship between soil moisture and ecosystem respiration and its water adaptation. Such knowledge facilitates understanding of soil moisture in affecting respiratory carbon emissions and has the potential to improve ...

Half a century of environmental variability and seabird trends on the Faroe Shelf in the North Atlantic Ocean

Frontiers in Marine Science
The Faroe Shelf, located on the North Atlantic’s Iceland-Scotland ridge, has historically hosted a rich ecosystem with large seabird populations. However, substantial declines in their population sizes have been observed over the past half century.
