Regime Shift in an Exploited Fish Community Related to Natural Climate Oscillations
Identifying the various drivers of marine ecosystem regime shifts and disentangling their respective influence are critical tasks for understanding biodiversity dynamics and properly managing exploited living resources such as marine fish communities. Unfortunately, the mechanisms and forcing factors underlying regime shifts in marine fish communities are still largely unknown although climate ...
متن کاملHypoxic areas, density-dependence and food limitation drive the body condition of a heavily exploited marine fish predator
Investigating the factors regulating fish condition is crucial in ecology and the management of exploited fish populations. The body condition of cod (Gadus morhua) in the Baltic Sea has dramatically decreased during the past two decades, with large implications for the fishery relying on this resource. Here, we statistically investigated the potential drivers of the Baltic cod condition during...
متن کاملConsistent size-independent harvest selection on fish body shape in two recreationally exploited marine species
Harvesting wild animals may exert size-independent selection pressures on a range of morphological, life history, and behavioral traits. Most work so far has focused on selection pressures on life history traits and body size as morphological trait. We studied here how recreational fishing selects for morphological traits related to body shape, which may correlate with underlying swimming behav...

متن کاملUrbanization and domestic accidents in an Iranian community
Background: Accidents, such as domestic accidents, and the resulting injuries are presently a matter of concern in communities. Some factors such as urbanization cause an increase in the incidence of accidents for recognized and unrecognized reasons. The aim of the present study was to investigate the incidence of domestic accidents among a group of families who had migrated to the determined u...
