This study examined arthropod community patterns over an altitudinal ecoregional zonation that extended through three ecoregions (Yungas, Monte de Sierras y Bolsones, and Puna) and two ecotones (Yungas-Monte and Prepuna) of Northwestern…
The selective properties of fishing that influence behavioural traits have recently gained interest. Recent acoustic tracking experiments have revealed between-individual differences in the circadian behavioural traits of marine free-living… The pumpkinseed (Lepomis gibbosus) is a North American freshwater fish of the sunfish family (Centrarchidae) of order Perciformes.

Environmental homogenization in coastal ecosystems impacted by human activities may be an important factor explaining the observed decline in fish species richness. We used fish community data (>200 species) from extensive surveys conducted…
17 Feb 2006 Community ecology is the study of a set of species co- occurring at a given time and place. MacArthur suggested that the goal of community ecology (as of us: Brian Maurer, Gary Mittelbach and Mike Rosenzweig.

Arthropod community structure (based upon 18 response variables) diverged over time between Supplemented and Ambient treatments, with no effect of Fencing on the multivariate response pattern. That biodiversity declines with latitude is well known, but whether a metacommunity process is behind this gradient has received limited attention. We tested the hypothesis that dispersal limitation is progressively replaced by mass effects… The results demonstrate that in this intertidal community, nutrient limitation can occur under conditions of nutrient stress, that top-down grazing effects are typically stronger than bottom-up nutrient effects, and that prey-dependent… In contrast to observations in the surface waters, the eukaryotic richness just below the thermocline showed three richness peaks and an increase near the equator. Carnivores can affect the impact that herbivores have on plants in two ways (4). They may cause changes in herbivore density through direct consumption of herbivores. C4 plants use the C4 carbon fixation pathway to increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and… The use of more than 100 song playback experiments reveals that birds give stronger responses to songs of closely related species in the Amazon than in temperate North America, suggesting that speciation is currently happening more slowly…
Shrimp spend most of their time on the bottom, where attacks are more often successful. Avoidance of the bottom microhabitat by tadpoles therefore improves survival. In addition, and also in contrast to plant restoration ecology, the community context for a predator tends to be usefully conceptualized around trophic interactions first and foremost. Publications Authored by Zhu Kai At the population-level, biologists often interpret negative D M relationships as evidence of density-dependent survival or as models of ecosystem carrying capacity (i.e., the ‘self-thinning rule’)4,5.

Coldenia is a monotypic genus of flowering plants traditionally included in the borage family, Boraginaceae sensu lato. It was assigned to the subfamily Ehretioideae, but molecular data revealed it to be more closely related to the genus…
