Ontogenetic niche partitioning in southern elephant seals from Argentine Patagonia
(Wiley Blackwell Publishing, Inc, 2020-12-12)
Elephant seals, Mirounga spp., are highly dimorphic, having different energetic requirements according to age and sex, and foraging in various ecological and oceanographic contexts. Resource partitioning has been shown for ...
Do woody and herbaceous species compete for soil water across topographic gradients? Evidence for niche partitioning in a Neotropical savanna
(Elsevier B.V., 2014-03-01)
Savannas are characterized by sparsely distributed woody species within a continuous herbaceous cover, composed mainly by grasses and small eudicot herbs. This vegetation structure is variable across the landscape, with ...
Diet and resource partitioning in Patagonian bats (Chiroptera: Vespertilionidae and Molossidae)
(Springer, 2021-06)
Partitioning of food resources is one of the main drivers of bat community organization. We investigated the trophic structure of the Patagonian bat ensemble which comprises eight insectivorous species classified in the ...
Do penguins share? Evidence of foraging niche segregation between but not within two sympatric, central-place foragers
(Inter-Research, 2016-04)
Niche theory predicts that sympatric species should differentiate ecologically in order to co-exist and conspecifics will also differentiate to reduce intra-specific competition. As central-place foragers, colonial breeding ...
Trophic niche partitioning of five skate species of genus Bathyraja in northern and central Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2020-09)
Overexploitation of marine communities can lead to modifications in the structure of the food web and can force organisms like elasmobranchs to change their feeding habits. To evaluate the impact that fisheries have on ...
Trophic niche differentiation in rodents and marsupials revealed by stable isotopes
(2016-04-01)
Tropical rainforests support the greatest diversity of small mammals in the world, yet we have little understanding about the mechanisms that promote the coexistence of species. Diet partitioning can favor coexistence by ...
Isotopic niche partitioning between two small cetacean species
(Inter-Research, 2021-02)
Commerson’s dolphin Cephalorhynchus commersonii and Peale’s dolphin Lageno - rhynchus australis live in sympatry along the southwestern South Atlantic Ocean, suggesting the existence of some degree of habitat partitioning ...
