Species niches, not traits, determine abundance and occupancy patterns: A multi-site synthesis
(Wiley-Blackwell, 2019-11-10)
Aim Locally abundant species are usually widespread, and this pattern has been related to properties of the niches and traits of species. However, such explanations fail to account for the potential of traits to determine ...
Dietary and isotopic specialization: The isotopic niche of three cinclodes ovenbirds
(2009)
By comparing the isotopic composition of tissues deposited at different times, we can identify individuals that shift diets over time and individuals with constant diets. We define an individual as an isotopic specialist ...
Temperature and pH define the realised niche space of arbuscular mycorrhizal fungi
(Wiley-Blackwell, 2021-03-04)
The arbuscular mycorrhizal (AM) fungi are a globally distributed group of soil organisms that play critical roles in ecosystem function. However, the ecological niches of individual AM fungal taxa are poorly understood. ...
Ecologia trófica e ecomorfologia da ictiofauna de igarapés maranhenses (Alcântara-MA)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2011-06-07)
The trophic ecology is one of the most important aspects to understand the role of a species in the community and in the ecosystem functioning. Studies regarding the feeding of fishes coupled to the ecomorphology of a ...
Evolutionarily significant units of the critically endangered leaf frog Pithecopus ayeaye (Anura, Phyllomedusidae) are not effectively preserved by the Brazilian protected areas network
(2017-01-01)
Protected areas (PAs) are essential for biodiversity conservation, but their coverage is considered inefficient for the preservation of all species. Many species are subdivided into evolutionarily significant units (ESUs) ...
Segregation of diets by sex and individual in South American fur seals
(2022-03-01)
Trophic niche width and individual specialization among marine predators are often subjected to seasonal constraints. Differences are expected to arise for sexually dimorphic species exposed to distinct ecological ...
Alimentary niche partitioning in the Galapagos sea lion, Zalophus wollebaeki
(Marine Biology, 2010)
Sea lions are generally considered opportunistic feeders. However, studies from different areas suggest their diet consists mostly of four to five types of prey. Previous studies in Galapagos sea lions have identified at ...
