The oral cavity promotes virulence of candida parapsilosis sensu stricto via up- regulation of BCR1
(2020)
Candida parapsilosis sensu stricto behaves as a frequent colonizer of niches of the oral cavity, predominantly in pathological conditions. Studies have suggested the influence of the ecological niche in the virulence of ...
Individual diet specialisation in sparrows is driven by phenotypic plasticity in traits related to trade-offs in animal performance
(Wiley Blackwell Publishing, Inc, 2019-01)
Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population niches should exhibit greater IS than ...
Human-modified landscapes narrow the isotopic niche of neotropical birds
(Springer, 2021-04-09)
Deforestation and habitat loss resulting from land use changes are some of the utmost anthropogenic impacts that threaten tropical birds in human-modified landscapes (HMLs). The degree of these impacts on birds' diet, ...
Ecological singularity of temperate mesopredatory myliobatoid rays (Chondrichthyes: Myliobatiformes)
(Csiro Publishing, 2016-06)
Many myliobatoid rays are important mesopredators, having significant effects on coastal benthic communities. In tropical and subtropical high-diversity oligotrophic ecosystems, they partition their trophic resources, which ...

Disentangling abiotic and biotic mechanisms behind the formation of heterospecific Nearctic-Neotropical shorebird flocks
(2020-12-01)
Defense, vigilance, and optimal foraging are frequently related to the formation of flocks in birds. Few studies concerning long-distance migrant shorebirds analyzed whether phylogeny and ecological similarities of species ...
Thermal niche helps to explain the ability of dung beetles to exploit disturbed habitats
(Scientific Reports, 2020-08-07)
In terrestrial ecosystems, insects face a wide range of temperatures among habitats and time; consequently, the thermal niche is one of the main determinants of habitat selection and temporal patterns of activity. The ...
Competition and resource breadth shape niche variation and overlap in multiple trophic dimensions
(2019-05-15)
Competition plays a central role in the maintenance of biodiversity. A backbone of classic niche theory is that local coexistence of competitors is favoured by the contraction or divergence of species' niches. However, ...
The effect of past defaunation on ranges, niches, and future biodiversity forecasts
(2022-01-01)
Humans have reshaped the distribution of biodiversity across the globe, extirpating species from regions otherwise suitable and restricting populations to a subset of their original ranges. Here, we ask if anthropogenic ...
