Westbury, Michael V.; De Cahsan, Binia; Dalerum, Fredrik; Noren, Karin; Hofreiter, Michael (Southern African Wildlife Management Association, 2019)The aardwolf (Proteles cristata) is a unique, insectivorous species of the family Hyaenidae. It occupies a disjunct range in eastern and southern Africa and is possibly a remaining member of a historical dog-like hyaena ...

Pena, Rocio; Schleuning, Matthias; Dalerum, Fredrik; Donoso, Isabel; Rodriguez-Perez, Javier; Garcia, Daniel (Elsevier, 2023-02)Abundance and trait-driven processes have both been identified as potential mechanisms in determining the occurrence of species interactions. However, little is known about how these two mechanisms interact to determine ...

Vigues, Jan; Noren, Karin; Wilkinson, Caitlin; Stoessel, Marianne; Angerbjorn, Anders; Dalerum, Fredrik (Wiley, 2022-06)Spatially synchronous fluctuations of animal populations have profound ecological consequences, especially in northern latitudes. Spatially coupled fluctuations are often seen in small rodent populations, albeit with ...

Dalerum, Fredrik; Belton, L.E. (Lydia) (Oxford University Press, 2015-01)Large carnivores are important ecosystem components but frequently suffer local extinctions. However, reintroductions and shifting conservation attitudes have lead to some population repatriations. Since the ecological ...

Naud, Lucy; Masviken, Johannes; Freire, Susana; Angerbjorn, Anders; Dalen, Love; Dalerum, Fredrik (Wiley Open Access, 2019-04)Environmental gradients are caused by gradual changes in abiotic factors, which affect species abundances and distributions, and are important for the spatial distribution of biodiversity. One prominent environmental ...

Belton, L.E. (Lydia); Cameron, Elissa Z.; Dalerum, Fredrik (Springer, 2018-07)Rapid urban expansion has led to an increase in carnivores that live close to human dominated environments. Some carnivore species have successfully adapted to these novel conditions and taken advantage of opportunities ...

Filella, Jordi Bartolome; Bonilla, Christian Carlos Quispe; Quispe, Edgar; Dalerum, Fredrik (Springer, 2023-01)Different non-invasive techniques have been used to determine herbivore diet composition from fecal samples, including micro-histological analysis of epidermal fragments. This method can provide reliable semi-quantitative ...

Marneweck, David G.; Cameron, Elissa Z.; Ganswindt, Andre; Dalerum, Fredrik (Elsevier, 2015-01)It is now widely recognized that mating systems contain both social and genetic components, where social components describe patterns of social associations while genetic components reflect patterns of mating activities. ...

Dalerum, Fredrik; Westbury, Michael V.; Nor en, Karin; Hofreiter, Michael (Taylor and Francis, 2017-05)The bat-eared fox, Otocyon megalotis, is the only member of its genus and is thought to occupy a basal position within the dog family. These factors can lead to challenges in complete mitochondrial reconstructions and ...

Penteriani, Vincenzo; López-Bao, José Vicente; Bettega, Chiara; Dalerum, Fredrik; Delgado, María del Mar; Jerina, Klemen; Kojola, Ilpo; Krofel, Miha; Ordiz, Andrés (Elsevier, 2017-02)Many countries promote wildlife observation as part of ecotourism offerings. The brown bear Ursus arctos is among the most targeted species for ecotourism in North America and Europe, making it an ideal candidate to examine ...
-
Masviken, Johannes; Dalerum, Fredrik; Cousins, Sara A.O. (Wiley Open Access, 2020-06)Changes in abiotic factors along altitudinal and latitudinal gradients cause powerful environmental gradients. The topography of alpine areas generates environmental gradients over short distances, and alpine areas are ...

Swanepoel, Lourens Hendrik; Somers, Michael J.; Dalerum, Fredrik (Nordic Council for Wildlife Research, 2015)Data on the population size and trends of large carnivores remains the cornerstone of effective management and conservation programs. However, such data are rarely available for the majority of large carnivore species. ...
-
Dalerum, Fredrik (Taylor & Francis, 2012-01)In this note I want to point out a potentially concerning bias in evolutionary hypothesis testing. In evolutionary research, deductive hypothesis testing is the most common way of achieving information on causal relationships ...

Westbury, Michael V.; Le Duc, Diana; Duchene, David A.; Krishnan, Arunkumar; Prost, Stefan; Rutschmann, Sereina; Grau, Jose H.; Dalen, Love; Weyrich, Alexandra; Noren, Karin; Werdelin, Lars; Dalerum, Fredrik; Schoneberg, Torsten; Hofreiter, Michael (Oxford University Press, 2021-09)During the Miocene, Hyaenidae was a highly diverse family of Carnivora that has since been severely reduced to four species: the bone-cracking spotted, striped, and brown hyenas, and the specialized insectivorous aardwolf. ...

Periquet, Stephanie; Richardson, Peter; Cameron, Elissa Z.; Ganswindt, Andre; Belton, L.E. (Lydia); Loubser, Elize; Dalerum, Fredrik (Wiley, 2017-09)Living under predation risk may alter both behaviour and physiology of potential prey. In extreme cases, such alterations may have serious demographic consequences, and recent studies support that non-lethal effects of ...

Dalerum, Fredrik; Cipollone, Mario; Cordischi, Fabrizio; Di Croce, Antonio; Ferri, Doriana; Giovannini, Silvia; La Civita, Filippo; Monaco, Antonio; Paglione, Gabriella; Paniccia, Chiara; Petriccione, Bruno; Romano, Mario; Shivij, Irene; Trei, Jan Niklas; Meloro, Carlo (Elsevier, 2024-02)Mammals have evolved to occupy spatial and temporal niches in order to optimize resource utilization and minimize predation risk or competition. Subsequently, niche partitioning may be influenced by phylogenetic associations, ...

Isaacs, Lisa; Somers, Michael J.; Dalerum, Fredrik (Wiley-Blackwell, 2013-03)Savannah ecosystems exhibit constant transitions between states dominated by trees and states dominated by a combination of trees and grasses. Transitions between these states are driven by interactions between fire and ...

Dalerum, Fredrik; Miranda, Maria; Muniz, Cristina; Rodriguez, Placido (Springer, 2018-02)For successful integration of biological conservation into economic markets, economic processes need to capture ecological values. South African wildlife ranching is a tourist-based activity that generates unique information ...

Penteriani, Vincenzo; Delgado, María Del Mar; Krofel, Miha; Jerina, Klemen; Ordiz, Andrés; Dalerum, Fredrik; Zarzo‐Arias, Alejandra; Bombieri, Giulia (Wiley, 2018-07)1. Evolutionary traps, and their derivative, ecological traps, occur when animals make maladaptive decisions based on seemingly reliable environmental cues, and are important mechanistic explanations for declines in animal ...

Dalerum, Fredrik; Freire, S.; Angerbjörn, Anders; Lecomte, Nicolas; Lindgren, Åsa; Meijer, Tomas; Pečnerová, P.; Dalén, Love (NRC Research Press, 2018)The grey wolf (Canis lupus Linnaeus, 1758) is one of the most widespread large carnivores on Earth, and occurs throughout the Arctic. Although wolf diet is well studied, we have scant information from high Arctic areas. ...
