Assessment of reproductive capacity in females of Callinectes danae Smith, 1869 (Brachyura, Portunoidea) during a period of high reproductive activity
Antunes, Mariana; Fransozo, Vivian ; Leão Castilho, Antônio ; José Cobo, Valter ; Teixeira, Gustavo Monteiro ; Fransozo, Adilson (Invertebrate Reproduction and Development, 2015) [Artigo]
The reproductive capacity of the swimming crab Callinectes danae Smith, 1869 was assessed based on the reproductive investment (RI) of ovigerous females and the gonadosomatic index (GI) of non-ovigerous adult females. Crabs ... -
Tree cavities used as diurnal roosts by Neotropical bats
; Uieda, Wilson (Folia Zoologica, 2014) [Artigo]
Bats occupy a variety of natural and artificial diurnal roosts. These environments offer several advantages for bats, among which we highlight the relative climatic stability, darkness, and protection from predators. The ... -
