Microhabitat use by two rocky shore gastropods in an intertidal sandy substrate with rocky fragments.
Sandy beaches in some areas of the São Sebastião Channel in southeastern Brazil have unremittingly undergone a variety of impacts, including the deposition of rock fragments in the intertidal region. Consequently, these environments support a rich fauna comprising both sandy beach and rocky shore organisms. Two rocky shore gastropods, Tegula viridula and Morula nodulosa, are particularly abunda...
متن کاملPositive and negative effects of mesograzers on early‐colonizing species in an intertidal rocky‐shore community
The ecological consequences of human-driven overexploitation and loss of keystone consumers are still unclear. In intertidal rocky shores over the world, the decrease of keystone macrograzers has resulted in an increase in the dominance of herbivores with smaller body (i.e., "mesograzers"), which could potentially alter community assembly and structure. Here, we experimentally tested whether me...
متن کاملCarcinus Maenas: a Demographic Study of an Invasive Shore Crab in the New England Rocky Intertidal
Carcinus maenas (Green Crab) is an invasive crab species on the east and west coasts of the United States dating back to 1817. The introduction of another invasive species in 1988, Hemigrapsus sanguineus (Asian Shore Crab), has created competitive interactions between the crabs. A demographic study was conducted to compare crab populations. A total of 155 crabs were collected, 25 of which were ...
متن کاملDiversity and distribution of True Crabs (Brachyura) from intertidal rocky shores of Qeshm Island, Persian Gulf
Rocky shores are one of the most important habitats of marine environment in coastal areas. This study was done in 2010-2011 to investigate the diversity of true crabs in intertidal rocky shores of Qeshm island. Samples were collected from intertidal zones during the low-tide at 5 stations. The specimens were fixed in 70% Etanol and transferred to laboratory for identification. Altogether, 15 c...
متن کاملClimate and recruitment of rocky shore intertidal invertebrates in the eastern North Atlantic.
Studies of the impacts of climate and climate change on biological systems often attempt to correlate ecological responses with basin-scale indices such as the North Atlantic Oscillation (NAO). However, such correlations, while useful for detecting long-term trends, are unable to provide a mechanism linking the physical environment and ecological processes. Here we evaluate the effects of the N...
