Accounting for Uncertainties in Biodiversity Estimations: A New Methodology and Its Application to the Mesopelagic Sound Scattering Layer of the High Arctic
(Peer reviewed; Journal article, 2022)Measures of biological diversity (biodiversity) are important for monitoring the state of ecosystems. Several indices and methods are used to describe biodiversity from field observations. Marine faunal biodiversity is ... -
Anthropogenic flank attack on polar bears: interacting consequences of climate warming and pollutant exposure
(Journal article; Peer reviewed, 2015)Polar bears (Ursus maritimus) are subjected to several anthropogenic threats, climate warming and exposure to pollutants being two of these. For polar bears, one of the main effects of climate warming is limited access to ... -
Biomorphogenic Feedbacks and the Spatial Organization of a Dominant Grass Steer Dune Development
(Peer reviewed; Journal article, 2021)Nature-based solutions to mitigate the impact of future climate change depend on restoring biological diversity and natural processes. Coastal foredunes represent the most important natural flood barriers along coastlines ... -
Breathing in the Cold: Seasonal Changes in the Ventilatory Pattern in a Small Boreal Passerine Bird
(Peer reviewed; Journal article, 2022)Small passerine birds in the north need to take advantage of several behavioral and physiological mechanisms to maintain energy balance during the winter characterized by low food supply, low ambient temperatures, and short ... -
Circadian rhythms of urinary cortisol levels vary between individuals in wild male chimpanzees: A reaction norm approach
(Journal article; Peer reviewed, 2018)Investigating the repeatability of trait variation between individuals, that is the amount of individual variation in relation to overall phenotypic variation, indicates an upper level of heritability and reveals whether ... -
Climate change and the increasing impact of polar bears on bird populations
(Journal article; Peer reviewed, 2015-03-25)The Arctic is becoming warmer at a high rate, and contractions in the extent of sea ice are currently changing the habitats of marine top-predators dependent on ice. Polar bears (Ursus maritimus) depend on sea ice for ... -
Contrasting Effects of Chronic Anthropogenic Disturbance on Activity and Species Richness of Insectivorous Bats in Neotropical Dry Forest
(Peer reviewed; Journal article, 2022)For prioritizing conservation actions, it is vital to understand how ecologically diverse species respond to environmental change caused by human activity. This is particularly necessary considering that chronic human ... -
The Ghost of the Hawk: Top Predator Shaping Bird Communities in Space and Time
(Peer reviewed; Journal article, 2021)Despite the wide recognition that strongly interacting species can influence distributions of other species, species interactions are often disregarded when assessing or projecting biodiversity distributions. In particular, ... -
Hydrogen cyanide, a key plant defense, as a potential driver of root-associated nematode communities along urbanization gradients
(Peer reviewed; Journal article, 2023)Introduction: Plant chemical defenses can influence the distribution, community composition, and abundance of soil biota. Urbanization plays a key role in shaping soil biotic communities either directly through changes in ... -
Location is everything, but climate gets a share: analyzing small-scale environmental influences on breeding success in the white-throated dipper
(Peer reviewed; Journal article, 2020)Ecological and evolutionary effects of environmental variation on wild populations are of particular interest in a changing world. Large-scale environmental indices are classically used as environmental explanatory variables ... -
Repeatable Territorial Aggression in a Neotropical Poison Frog
(Peer reviewed; Journal article, 2022)Intra-specific aggressive interactions play a prominent role in the life of many animals. While studies have found evidence for repeatability in boldness, activity, and exploration in amphibians, we know relatively little ... -
There is more to climate than the North Atlantic Oscillation: a new perspective from climate dynamics to explain the variability in population growth rates of a long-lived seabird
(Journal article; Peer reviewed, 2015)Predicting the impact of global climat echange on the biosphere has become one of the most important efforts in ecology. Ecosystems worldwide are changing rapidly as a consequence of global warming, yet our understanding ...
