Intraspecific variability drives diversity in food webs [PDF]
, 2011 Biodiversity theories neglect individual-level variability in ecological interactions even though empirical work has revealed considerable genetic and phenotypic variation among individuals in natural populations.

How to coexist with fire ants: The roles of behaviour and cuticular compounds [PDF]
, 2013 tBecause territoriality is energetically costly, territorial animals frequently respond less aggressively toneighbours than to strangers, a reaction known as the “dear enemy phenomenon” (DEP).

Phosphorus-limited Daphnia: Intraspecific facilitation instead of competition [PDF]
Limnology and Oceanography, 1992 P-limited chemostat cultures of the green alga Scenedesmus acutus were inoculated with the herbivorous zooplankter Daphnia galeata after steady state had been reached. At low dilution rates (up to 0.5 d-l) and consequently low P content of the food algae (P: C < 0.0011) Daphnia could not grow.

Ecography, EarlyView.Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Secondary reproductive strategies in Pacific black brant (Branta bernicla nigricans) [PDF]
, 1999 Thesis (M.S.) University of Alaska Fairbanks, 1999Waterfowl are known to use secondary reproductive strategies, both extra-pair copulations and intraspecific brood parasitism, to increase fitness. We used five polymorphic microsatellite loci to determine

The presence of webbing affects the oviposition rate of two-spotted spider mites, Tetranychus urticae (Acari: Tetranychidae) [PDF]
, 2009 Several species of tetranychid mites including Tetranychus urticae Koch (Acari: Tetranychidae) construct complicated three-dimensional webs on plant leaves. These webs provide protection against biotic and abiotic stress.

Ecography, EarlyView.Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients
Ecography, EarlyView.Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.
