Antibacterial and antiparasitic effects of Bothrops marajoensis venom and its fractions: Phospholipase A(2) and L-amino acid oxidase
(Toxicon, 2010-04-01) [Artigo]
Some proteins present in snake venom possess enzymatic activities, such as phospholipase A(2) and L-amino acid oxidase. In this study, we verify the action of the Bothrops marajoensis venom (BmarTV), PLA(2) (BmarPLA(2)) ...
IS CLEISTOSPERMY AND COENOSPERMY RELATED TO SPERM TRANSFER? A COMPARATIVE STUDY OF THE MALE REPRODUCTIVE SYSTEM OF PACHYGRAPSUS TRANSVERSUS AND PACHYGRAPSUS GRACILIS (BRACHYURA: GRAPSIDAE)
(Journal Of Crustacean Biology, 2014-11-01) [Artigo]
We describe the production of spermatophores and the seminal fluid in Pachygrapsus transversus and P. gracilis. Both species have tubular testes. The vas deferens is divided into anterior (AVD), middle (MVD), and posterior ...
SPERMATOGENESIS, SPERMATOPHORE, and SEMINAL FLUID PRODUCTION IN THE ADULT BLUE CRAB CALLINESTES DANAE (PORTUNIDAE)
(Journal of Crustacean Biology, 2012-03-01) [Artigo]
Sperm and spermatophore production in Callinectes danae Smith, 1869 were examined by histochemistry and correlated with gonadosomatic (GSI) and hepatosomatic (HSI) indices. The GSI from developing (DE) and mature (MAT) ...
Relative abundance and population biology of the non-indigenous crab Charybdis hellerii (Crustacea: Brachyura: Portunidae) in a southwestern Atlantic estuary-bay complex
(Aquatic Invasions, 2012-09-01) [Artigo]
Invasive species are potential threats to biodiversity, especially if they become established and outnumber native species. In this study, a population of the non-indigenous crab Charybdis hellerii was analyzed in an ...
Male reproductive system of the red brocade hermit crab Dardanus insignis (Diogenidae) and its relationship to other family members
(Zoomorphology, 2014-06-01) [Artigo]
The reproductive system of hermit crabs shows species-specific morphology, which can be used in phylogenetic analysis. Here, we describe the male reproductive system of the hermit crab Dardanus insignis, including morphological ...
