We used the unsupervised machine learning technique to evaluate the environmental factors responsible for modulating the spatial and seasonal distribution of caridean shrimps from a southeastern region of the Brazilian coast. Samplings were collected from seven transects with an artisanal shrimp fishery boat with two double‐rig nets. Samplings occurred every month from October 2008 to September 2009...
Biodiversity studies might help to understand the ecological dynamics of regions under the influence of upwelling and serve as a baseline to conservation and management strategies. Here, we evaluated the alpha (species richness and Shannon‐Wienner index – H’) and beta (Bray Curtis index) diversities of a Brachyura assemblage within a depth gradient (5, 10, 15, 25, 35, and 45 m) in the Macaé region,...
The aim of this study was to evaluate the spatio-temporal variation and influence of environmental factors on the reproduction of H. pudibundus, and to estimate the size at the onset of sexual maturity (CW50). Samples were taken monthly from January to December 2000 in nine transects ranging from 2 to 40 m of depth. Bottom temperature, salinity, and sediment texture were recorded at each transect...
This study compares the abundance and the spatio-temporal distribution of the shrimps Artemesia longinaris and Pleoticus muelleri, and their relationship with environmental factors (bottom temperature and salinity; sediment texture) at Fortaleza Bay, in Ubatuba, São Paulo State. We performed the samplings from November 1988 until October 1989, and repeated it 20 years later, from November 2008 until...
