Population biology of Uca maracoani Latreille 1802-1803 (Crustacea, Brachyura, Ocypodidae) on the south-eastern coast of Brazil
The population biology of Uca maracoani was investigated in an estuarine mudflat in the Jabaquara River, Paraty, Brazil. The following aspects of this population were analyzed: spatial distribution,Expand
Relative growth, morphological sexual maturity, and size of Macrobrachium amazonicum (Heller 1862) (Crustacea, Decapoda, Palaemonidae) in a population with an entirely freshwater life cycle
The objective of this study was to estimate the size of morphological sexual maturity based on the study of relative growth, to determine the maximum size of individuals, and to determine if thereExpand
Comparison of body size, relative growth and size at onset sexual maturity of Uca uruguayensis (Crustacea: Decapoda: Ocypodidae) from different latitudes in the south-western Atlantic
Some crustaceans show variations of their reproductive biology within their geographical distribution, and knowledge about such variations is important for the comprehension of their reproductiveExpand
Population dynamic of Sesarma rectum (Crustacea, Brachyura, Sesarmidae) from a muddy flat under human impact, Paraty, Rio de Janeiro, Brazil
A population of Sesarma rectum Randall, 1840 under the influence of human impact was studied. Monthly sampling (CPUE, two people during 30 min) took place from August/2001 to July/2002 at an impactedExpand
Temporal and spatial distribution of the commercial shrimp Litopenaeus schmitti (Dendrobranchiata: Penaeidae) in the south-eastern Brazilian coast
The goal of the present study was to assess the temporal and spatial distribution of L. schmitti in three bays of the northern coast of the State of São Paulo, Ubatumirim (UBM), Ubatuba (UBA) and MarExpand
Differentiation in Selection of Dicots and Grasses by the Leaf-Cutter Ants Atta capiguara, Atta laevigata and Atta sexdens rubropilosa
Besides foraging for grasses, the so-called grass-cutter ants, such as Atta capiguara (Hym., Formicidae, Attini), have shown, in the laboratory, a high preference for dicots including Acalypha spp.Expand
New records of decapod crustaceans from the coast of Sergipe state, Brazil
The objective of this study is to report seven decapod crustacean species for the first time from Sergipe state, northeastern Brazil. The specimens were sampled from January 2012 to June 2015, onExpand
Morphological and morphometric comparisons of the first zoea of four species of purse crabs (Decapoda: Brachyura: Leucosiidae) from the Brazilian South Atlantic
Morphological descriptions of the first larval stages of Persephona mediterranea, P. lichtensteinii and P. punctata (Leu-cosiidae: Eballinae) from the South Atlantic are provided, with comparisonsExpand
Growth and population structure of the seabob shrimp Xiphopenaeus kroyeri (Decapoda: Penaeidae) on the continental shelf of Sergipe, Brazil
This study evaluated the population structure, growth and longevity of Xiphopenaeus kroyeri in the State of Sergipe. The obtained data were compared with other populations on a latitudinal scale inExpand
Morphological variation in males of Dendrocephalus orientalis (Anostraca: Thamnocephalidae): Implications for species identification.
The genus Dendrocephalus Daday, 1908 consists of 17 described species. The morphology of the frontal appendage and the first pairs of thoracopods of males are the main characteristics used forExpand
