Beaver foraging patterns in a human-dominated landscape: Effects on woody vegetation and mammals
Svanholm Pejstrup, Malene; Andersen, Jonas; Mayer, Martin (Peer reviewed; Journal article, 2023)Beavers can change habitat composition by cutting down trees, digging, and damming activities, thereby affecting species richness and abundance. Although there is large body of literature regarding the effects of beaver ... -
Citizen Observations Shed New Light on Geographic Variation in Colour Polymorphism of a Widespread Reptile
Niels, Jansen; Pruijn, Nick; Mayer, Martin (Peer reviewed; Journal article, 2024)Aim Colour polymorphism within ectothermic species and populations is shaped by multiple selection pressures that can vary geographically. Here, we tested different hypotheses to better understand this variation in colour ... -
Co-occurrence patterns and habitat selection of the mountain hare, European hare, and European rabbit in urban areas of Sweden
Bach, Henriette; Escoubet, Hannah; Mayer, Martin (Peer reviewed; Journal article, 2023)Assessing the underlying mechanisms of species co-occurrence patterns can be challenging as biotic and abiotic factors are hard to disentangle. To date, few studies have investigated co-occurrence patterns of mammals within ... -
Drone-borne monitoring of moose
Mayer, Martin; Vogler, Thomas; Ausilio, Giorgia; Kirchner, Theresa; Mathisen, Karen Marie; Evans, Alina L.; Eriksen, Ane; Heurich, Marco; Naumov, Vladimir; Wabakken, Petter; Zimmermann, Barbara (Oppdragsrapport;4/2024, Research report, 2024)Norsk: Droner er en lovende ny teknologi for overvåking av viltbestander. I dette prosjektet evaluerte vi bruken av droner som et verktøy for overvåking av elg (Alces alces) populasjoner og beiting i den skandinaviske ... -
Dune Hares: Population Indices, Home Range Size, and Habitat Selection of the European Hare on a Danish Island
Högberg Kleist, Majbrit; Mohr Mortensen, Rasmus; Bregnballe, Thomas; Mayer, Martin (Peer reviewed; Journal article, 2024)Population indices, such as transect counts of animals, can provide important information concerning population changes over time. Moreover, data concerning the home range size and habitat selection of individuals can ... -
High infection intensities, but negligible fitness costs, suggest tolerance of gastrointestinal nematodes in a tropical snake
Mayer, Martin; Brown, Gregory P.; Zimmermann, Barbara; Shine, Richard (Journal article; Peer reviewed, 2015)We investigated patterns of prevalence and intensity of gastrointestinal nematode infections in a tropical natricine snake, the keelback (Tropidonophis mairii). Ninety-eight per cent of keelbacks were infected with Tanqua ... -
Influence of roads on space use by European hares in different landscapes
Mayer, Martin; Fischer, Christina; Blaum, Niels; Sunde, Peter; Ullmann, Wiebke (Peer reviewed; Journal article, 2022)Context Roads are ubiquitous in human inhabited landscapes, and can impact animal movement and population dynamics, due to barrier effects, road mortality, but also by providing resources at road verges. Thus, we need a ... -
Intraspecific divergence of sexual size dimorphism and reproductive strategies in a polytypic poison frog
Schlippe Justicia, Lia; Mayer, Martin; Lorioux-Chevalier, Ugo; Dittrich, Carolin; Rojas, Bibiana; Chouteau, Mathieu (Peer reviewed; Journal article, 2023)Intraspecifc variation in body size, both among populations and between sexes, is an important factor infuencing life-history strategies. This variation might be the response to diferent environmental conditions, as well ... -
Mammal responses to predator scents across multiple study areas
Sunde, Peter; Böcker, Felix; Rauset, Geir Rune; Kjellander, Petter; Chrenkova, Monika; Skovdal, Trine Munck; Calkoen, Suzanne van Beeck; Mayer, Martin; Heurich, Marco Dietmar (Peer reviewed; Journal article, 2022)Antipredator behaviors allow prey to mitigate the impacts of their predators. We investigated antipredator responses of two herbivore species, roe deer and European hare, and one mesopredator, red fox, toward predation ... -
Poison in the nursery: Mercury contamination in the tadpole-rearing sites of an Amazonian frog
Schlippe Justicia, Lia; Lemaire, Jeremy; Dittrich, Carolin; Mayer, Martin; Bustamante, Paco; Rojas, Bibiana (Peer reviewed; Journal article, 2024)Artisanal and small-scale gold mining (ASGM) has become a major threat for Neotropical forests. This technique for obtaining gold is a substantial driver of small-scale deforestation and the largest contributor of Hg ... -
Retention and loss of PIT tags and surgically implanted devices in the Eurasian beaver
Mayer, Martin; Fuchs, Boris; Robstad, Christian; Evans, Alina; Perrin, Kathryn; Greunz, Eva M.; Laske, Timothy G.; Arnemo, Jon Martin; Rosell, Frank Narve (Peer reviewed; Journal article, 2022)Passive integrated transponder devices (PIT tags) are a valuable tool for individual identification of animals. Similarly, the surgical implantation of transmitters and bio-loggers can provide useful data on animal location, ... -
Scared as a hare: Effects of capture and experimental disturbance on survival and movement behavior of European hares
Mayer, Martin; Haugaard, Lars; Sunde, Peter (Peer reviewed; Journal article, 2021)Capture and handling of wildlife is an important component of wildlife studies, and hunting can be a central tool for wildlife management. However, human-caused disturbance of animals can cause various negative effects on ... -
Using animal–vehicle collision data for wildlife population monitoring
Lind Hansen, Jonathan; Sunde, Peter; Skovbjerg Balsby, Thorsten Johannes; Mayer, Martin (Peer reviewed; Journal article, 2024)Globally, collisions with vehicles result in millions of animal deaths every year, representing a major issue for wildlife conservation and management. Consequently, and importantly, much research has focused on understanding ...
