Dear Marmamers, I'm pleased to share a recent publication from our research
Figueiredo, G.C.; do Amaral, K.B. and Santos, M.C. de O. 2020. Cetaceans
along the southeastern Brazilian coast: occurrence, distribution and niche
inference at local scale. PeerJ 8: e10000.
Abstract: It is deemed important to understand cetacean occurrence and
comprehend their ecological roles. The geographical occurrence of species'
be used to better describe their potential distribution. The niche can be
environmental variables. Those variables are considered static and not
biological activities. The present study goal was to assess the occurrence
of cetaceans along the southeastern Brazilian coast, as well as to define
and realized niche of each species and to investigate niche overlap at
The environmental requirements for each species were also investigated
statistical tests. Sighting data were obtained through oceanographic
between 2012 and 2015. The environmental variables available on MARSPEC and
software NicheA were used for the ecological niche modeling. A total of
species were identified and the potential distribution areas of the six
were defined. Even though the species presented different environmental
most of them had partial overlap among niches and potential distribution
environmental heterogeneity of the study area might support the
different species with different environmental requirements.
