Animal-borne video systems provide insight into the reproductive behavior of the Asian black bear
Naganuma, Tomoko; Tanaka, Mii; Tezuka, Shiori; Steyaert, Sam; Tochigi, Kahoko; Inagaki, Akino; Myojo, Hiroaki; Yamazaki, Koji; Koike, Shinsuke (Peer reviewed; Journal article, 2021)Previous studies on the mating system of the Asian black bear (Ursus thibetanus) have been limited to observations of captive populations and estimations of multiple paternities. Hence, the mating system of wild bears ... -
The Aquatic Surface Robot (AnSweR), a lightweight, low cost, multipurpose unmanned research vessel
Sanfilippo, Filippo; Tang, Min; Steyaert, Sam (Communications in Computer and Information Science;, Chapter; Peer reviewed, 2021) -
Beaver (Castor fiber) activity and spatial movement in response to light and weather conditions
Cabre, L, B.; Mayer, M; Steyaert, Sam; Rosell, Frank Narve (Peer reviewed; Journal article, 2020)Animal behaviour can affect individual fitness and is influenced by exogenous and endogenous factors. Here, we investigated how light (daylight length and moonlight), weather (precipitation and temperature), age, sex and ... -
Differentiation and seasonality in suitable microsites of seed dispersal by an assemblage of omnivorous mammals
Tochigi, Kahoko; Steyaert, Sam; Naganuma, Tomoko; Yamazaki, Koji; Koike, Shinsuke (Peer reviewed; Journal article, 2022) -
Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
Arnberg, Mie Prik; Frank, Shane; Blaalid, Rakel; Davey, Marie Louise; Eycott, Amy Elizabeth; Steyaert, Sam (Peer reviewed; Journal article, 2022) -
Directed endozoochory : a hitchhiker’s guide to successful sexual reproduction in clonal ericaceous plants
Arnberg, Mie Prik (PhD in Aquatic Biosciences;no. 52, Doctoral thesis, 2023) -
Do ingredient and nutrient intake reveal individual dietary specialization in an omnivorous carnivore, the brown bear?
De Cuyper, Annelies; Strubbe, Diederik; Clauss, Marcus; Lens, Luc; Zedrosser, Andreas; Steyaert, Sam; Kopatz, Alexander; Janssens, Geert P.J. (Peer reviewed; Journal article, 2024)Generalist populations often harbor individual dietary specialists. Whether using a narrower set of resources than the population (= specialization) affects specialists' nutrient intake remains underexplored. We evaluated ... -
Endozoochory by brown bears stimulates germination in bilberry
Steyaert, Sam; Hertel, Anne Gabriela; Swenson, Jon (Peer reviewed; Journal article, 2019)The understory vegetation of the Eurasian boreal forest is dominated by several ericaceous species (e.g. bilberry Vaccinium myrtillus). These species invest large amounts of energy in their sexual reproduction by producing ... -
Fear the reaper : ungulate carcasses may generate an ephemeral landscape of fear for rodents : Rodents fear scavengers at mass die-off
Frank, Shane; Blaalid, Rakel; Mayer, Martin; Zedrosser, Andreas; Steyaert, Sam (Peer reviewed; Journal article, 2020)Animal carcasses provide an ephemeral pulse of nutrients for scavengers that use them. Carcass sites can increase species interactions and/or ephemeral, localized landscapes of fear for prey within the vicinity. Few studies ... -
Grading fecal consistency in an omnivorous carnivore, the brown bear : Abandoning the concept of uniform feces
De Cuyper, Annelies; Clauss, Marcus; Lens, Luc; Strubbe, Diederik; Zedrosser, Andreas; Steyaert, Sam; Saravia, Arturo Muñoz; Janssens, Geert P.J. (Peer reviewed; Journal article, 2021)Grading the fecal consistency of carnivores is a frequently used tool for monitoring gut health and overall digestion. Several fecal consistency grading systems are available for mainly felids and canids. No such system ... -
Gut microbiome biogeography in reindeer supersedes millennia of ecological and evolutionary separation
Kamenova, Stefaniya; de Muinck, Eric; Veiberg, Vebjørn; Utsi, Tove Hilde Ågnes; Steyaert, Sam; Albon, Steve; Loe, Leif Egil; Trosvik, Pål (Peer reviewed; Journal article, 2023) -
Land cover type modulates the distribution of litter in a Nordic cultural landscape
Eide, Sara Kristiane Kjærgård; Leh, Linn N.; Eines, Katinka S.; Hovland, Ingunn; By, Marit; Ingvaldsen, Elise W.; Tinlund, Marthe; Machado, Luciano A.; Brønner, Stian; Nilsen, Erlend Birkeland; Steyaert, Sam; Eremita, Evan (Peer reviewed; Journal article, 2022)Litter pollution is a global environmental problem that occurs in virtually all ecosystems. Scientific research on anthropogenic litter and its environmental impacts focusses predominantly on plastics and the marine ... -
Perfect poopers ; passerine birds facilitate sexual reproduction in clonal keystone plants of the boreal forest through directed endozoochory towards dead wood
Arnberg, Mie Prik; Patten, Michael A.; Klanderud, Kari; Haddad, Camela; Larsen, Oddbjørn; Steyaert, Sam (Peer reviewed; Journal article, 2023) -
Reindeer carcasses provide foraging habitat for insectivorous birds of the alpine tundra
Badia, Rudy; Steyaert, Sam; Puliti, Stefano; Blaalid, Rakel; Frank, Shane (Peer reviewed; Journal article, 2019)On August of 2016, almost an entire herd (n = 323) of wild tundra reindeer (Rangifer tarandus) was killed by lightning on Hardangervidda in southern Norway. While conducting fieldwork for another study in 2017, we ...
