Spatial 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 کاملModification of Ecosystems by Ungulates
Ecosystem ecologists traditionally have focused their attention on direct interactions among species, particularly those interactions that control flows of energy and materials among trophic levels. Emerging evidence suggests that indirect interactions may be more important than direct ones in determining ecosystem patterns and processes. Here I review indirect effects of ungulates on nutrient ...
متن کاملNationwide trophic cascades: changes in avian community structure driven by ungulates
In recent decades, many ungulate populations have changed dramatically in abundance, resulting in cascading effects across ecosystems. However, studies of such effects are often limited in their spatial and temporal scope. Here, we contrast multi-species composite population trends of deer-sensitive and deer-tolerant woodland birds at a national scale, across Britain. We highlight the divergent...
متن کاملMurray Et Al. 1 Running Head: Ungulates and N Availability in Space 1
10 Spatial heterogeneity of soil resources, particularly nitrogen availability, affects herbaceous-layer 11 cover and diversity in temperate forest ecosystems. Current hypotheses predict that ungulate 12 herbivores influence nitrogen availability at the stand scale, but how ungulates affect nitrogen 13 availability at finer spatial scales that are relevant to the herb-layer is less understood. ...
