Anthropogenic fire patterns affect niche breadth and niche overlap in sympatric songbird species [PDF]
The severity of wildfires increases globally, and return intervals decrease. Fires can benefit biodiversity, as post-burn early successional stages provide diverse habitats and niches for many species. How fire disturbance affects niche use and niche overlap of species is poorly understood so far. We studied the effect of anthropogenic fire on breeding

Dispersal ability and niche breadth influence interspecific variation in spider abundance and occupancy [PDF]
The relationship between species local abundance and their regional distribution (occupancy) is one of the most extensively recognized and investigated patterns in ecology. While exceptions exist, the generally held model is that locally abundant species

Decreased thermal niche breadth as a trade-off of antibiotic resistance. [PDF]
Abstract Evolutionary theory predicts that adaptations, including antibiotic resistance, should come with associated fitness costs; yet, many resistance mutations seemingly contradict this prediction by inducing no growth rate deficit.

Experimental evolution for niche breadth in bacteriophage T4 highlights the importance of structural genes [PDF]
Ecologists have long studied the evolution of niche breadth, including how variability in environments can drive the evolution of specialism and generalism.

Habitat niche breadth predicts invasiveness in solitary ascidians. [PDF]
AbstractA major focus of invasion biology is understanding the traits associated with introduction success. Most studies assess these traits in the invaded region, while only few compare nonindigenous species to the pool of potential invaders in their native region.

Pulsed resource availability changes dietary niche breadth and partitioning between generalist rodent consumers [PDF]
Identifying the mechanisms that structure niche breadth and overlap between species is important for determining how species interact and assessing their functional role in an ecosystem.

Predicting occupancy and abundance by niche position, niche breadth and body size in stream organisms [PDF]
The regional occupancy and local abundance of species are thought to be strongly correlated to their body size, niche breadth and niche position. The strength of the relationships among these variables can also differ between different organismal groups.

Agricultural constraints on microbial resource use and niche breadth in drainage ditches [PDF]
Background Microorganisms govern important ecosystems processes, in particular the degradation of organic matter (OM). However, microorganisms are rarely considered in efforts to monitor ecosystem health and functioning.

Niche occupation limits adaptive radiation in experimental microcosms. [PDF]
Adaptive radiations have played a key role in the evolution of biological diversity. The breadth of adaptive radiation in an invading lineage is likely to be influenced by the availability of ecological niches, which will be determined to some extent by ...
