Many ecological systems experience periodic variability. Theoretical investigation of
population and community dynamics in periodic environments has been hampered by the …

Structured compartmental models in mathematical biology track age classes, stage classes,
or size classes of a population. Structured modeling becomes important when mechanistic …

Phenology is a crucial life history trait for species interactions and it can have great
repercussions on the persistence of communities and ecosystems. Changes in phenology …

Whether and how differences in environmental predictability affect life-history traits is
controversial and may depend on mean environmental conditions. Solid evidence for effects …

Ecological theory about the dynamics of interacting populations is mainly based on
unstructured models that account for species abundances only. In turn, these models …

Historically colder regions of the North Atlantic had fisheries dominated by only a few fish
species; principally cod and capelin. Possible population dynamic mechanisms that lead to …

In this paper we consider a periodic non-autonomous competitive stage-structured system
with infinite delay for the interaction between n species, the adult members of which are in …

In this paper, we investigate the asymptotic behavior for a kind of resource competition
model with environmental noises. Considering the impact of white noise on birth rate and …

[eng] A central theme in ecology and evolution is to understand whether and how species
respond to environmental changes. The amount of studies focusing on how species might …

Results Climatic differences among years and seasons. Air temperatures significantly
differed between periods (F2, 941= 512.450, P< 0.001) and no significant differences …
