Impact of climate change on population dynamics and temporal patterns of benthic assemblages of rivers
نویسندگان
چکیده
Seasonal cycles of temperature, water regime and day length act as “Zeitgeber” (timer) triggering stage transitions in the life cycle of organisms provoking temporal patterns of communities at different levels of organization. Climate change is both affecting temperature forcings and water regime. Mathematical models are set up to investigate the mechanisms for the change of temporal patterns in aquatic invertebrates as brought about by climate change.

Impact of Climate Change on Fisheries and Aquaculture Activities in Southern Iraq
The impacts on aquaculture and fisheries sectors from climate change in the southern part of Iraq will likely to be both positive and negative arising from direct and indirect impacts on natural resources. The main elements of climate change that could potentially impact fisheries and aquaculture activities in Iraq are temperature, rain patterns, shortage of freshwater, circulation, upwelling, ...
متن کاملDetecting the Impact of Climate Change Droughts on Changes in Groundwater Resources. Case Study: Birjand County
Increasing atmospheric anomalies have altered some of the extreme events such as global warming droughts, many climatic components such as precipitation, evapotranspiration, temporal and spatial distribution of precipitation, followed by dominoes of changes in freshwater resources available to communities. Human changes such as changes in the hydrological regime of rivers, changes in the qualit...
متن کاملSpatial and temporal patterns of benthic macrofauna in Gorgan Bay, south Caspian Sea, Iran
We quantified the distribution, abundance and assemblage structure of macrofauna at 22 stations in Gorgan bay, seasonally in 2012-2013. Also, depth, temperature, salinity, DO, TOM and sediment particle size were measured in each station. The highest concentration of TOM was measured near the western littoral zone (10.22) while the mouth part and north-eastern area was characterized by the lowes...
متن کاملSpatial and Temporal Patterns of Eastern Australia Subtropical Coral Communities
Despite increases in the frequency and intensity of disturbances on coral reefs over the past few decades, the response of subtropical coral assemblages to climate change is poorly understood. To address this knowledge gap on Australian reefs and provide a baseline for future comparisons, we quantified spatial (10-100's of kilometres) and temporal (decadal) patterns of benthic assemblages acros...

This study focuses on temporal changes in Atlantic salmon (Salmo salar) populations from the vulnerable periphery of the species range (northern Spain). Using microsatellite markers to assess population structuring and introgression of exogenous genes in four different temporal samples collected across 20 years, we have determined the relative weights of climate and stocking practices in shapin...
