Introduction
Most of my publications are dedicated to investigating marine decapod crustaceans (ecology, reproduction, growth and development. My expertise relies on larval and juvenile development of decapods, mainly, crabs and hermit crabs. I have been involved with an international proposal with respect to decapods’ ornamental aquaculture and reproductive traits’ morphology. We believe that only with better knowledge on marine species, we will contribute effectively to their protection.

Description
  • During this study we noted that some crabs’ megalopae were not described yet. Thus some larval raisings were carried out at lab. We’ve got juveniles of seven species from which we could identify the species of each megalopae.

Negreiros-Fransozo (2021) The spatial and temporal abundance of the spider crab Libinia ferreirae
Article
Full-text available
Symbiotic relationships in marine environments are not fixed and can change throughout the animal’s life. This study investigated the ontogeny of symbiosis of the spider crab Libinia ferreirae with the host medusa Lychnorhiza lucerna. We described the type of relationship, the temporal correlation among species and food habits. More than 50% of the...
Article
The spatial and seasonal distributions of benthic marine organisms are generally linked to the physical and chemical features of the environment. The abundance of Libinia ferreirae Brito Capello, 1871 was analysed in relation to the environmental factors: water temperature (surface and bottom), water salinity (bottom), and substratum (texture and o...
Article
Symbioses are ubiquitous in the animal kingdom. However, in most cases, the role of each member is relatively fixed, and it is rare for the same species to exhibit different symbiotic behaviours throughout its ontogeny. Here, we use stable isotope analyses of food resources to identify the relationships between the spider crab Libinia ferreirae as...
Article
We evaluated the mating behavior of Potimirim potimirim in the laboratory based on the assumption that this caridean might be hermaphroditic. We also performed histology and scanning electron microscopy analyses of the reproductive system of females, males, and differentiated individuals. The mating experiments produced three behavioral stages, nam...

In ecology, interaction networks allow the investigation of how interactions among species affect community structure and functioning. The structure of interaction networks can be nested and/or modular. Ecologically, the nested structure minimizes competition and increases the number of coexisting species, creating high diversity, while the modular...

The crayfish Procambarus clarkii (Girard, 1852) is a native species from the south-central region of the USA and northeastern Mexico that has been introduced to all continents except Antarctica and Oceania. In Brazil, P. clarkii has 17 established populations, all found in the southeastern region. The studied specimens were obtained at Ribeirão Cla...

The shrimp Potimirim brasiliana plays an important role in streams along the Brazilian coast as it feeds on the organic debris from the surrounding ecosystem. We determined the morphological sexual maturity of P. brasiliana by means of relative growth. Monthly throughout a year, we used sieves (2 mm mesh diameter) to collect the specimens in a coas...

Feeding strategies provide essential information to help understand symbiotic relationships and resource competition as well as environmental integrity. This study examined the feeding ecology of the spider crab Libinia ferreirae, which is commonly associated with the jellyfish Lychnorhiza lucerna during part of its life cycle, especially the juven...
Article
Full-text available
Different relationships are observed among many Majoidea crabs and other animals, as cnidarians. For the spider crab Libinia ferreirae Brito Capello, 1871 the interspecific relationships vary throughout its ontogeny; thus, the last larval stage (megalopa) and juveniles usually are associated with the jellyfish Lychnorhiza lucerna Haeckel, 1880, and...

Sexual maturity of the spider crab Libinia ferreirae was assessed for each sex, based on body dimensions and observations of gonad condition. A total of 346 crabs were analysed, of which 68% were females. Immature and adult individuals were recognized based on their allometric growth and gonad development. Abdomen width (AW) vs carapace width (CW)...

The early juvenile life period of Cherax quadricarinatus is characterized as a non feeding phase, once they remain attached to the female up to the third postembryonic stage. The brood care by females may prevent these tiny juveniles from predation; and the non-feeding behavior probably facilitates this care until the could to take the risk during...

Fiddler crabs are deposit feeders, and use the setae on their mouth appendages to manipulate sediment particles to extract food. The number of spoon-tipped setae on the second maxilliped is frequently related to the distribution of fiddler crabs on estuarine sediments, but no study has compared the morphological diversity of these setae among multi...

The identification of juvenile brachyurans obtained from the wild is extremely difficult, because the juveniles of most species have different features from the adults. Furthermore, studies on the post-embryonic development of brachyuran crabs are few. Nothing is known about the juvenile development of members of the Pseudorhombilidae. The present...
