“…A second paper (Magalhães and Türkay, 1996c) dealt with two genera of Dilocarcinini, Fredilocarcinus Pretzmann, 1978 (three species) and Goyazana Bott, 1969a (two species), and added two new species: Fredilocarcinus apyratii Magalhães and Türkay, 1996c, from the southwestern Brazilian Amazon, and Goyazana rotundicauda Magalhães and Türkay, 1996c, from the western Amazon region in Brazil, Peru and Ecuador. These were the last taxa to be described for the family in the last 20 years and this long period could suggest that the "discovery" phase for the family might be ending (Yeo et al, 2008;Magalhães et al, 2016).…”

“…Scientifically, besides the description of the first pseudothelphusid crab from the southern tributaries of the Amazon River (Magalhães and Türkay, 1986), the important decision was made to embark on a revision of the Trichodactylidae. The systematics of the family was quite confusing (see above) and solving most of the problems required examining type material and gathering good collections from Brazil, as this group has its highest diversity in this country (Cumberlidge et al, 2014;Magalhães et al, 2016). One of the most compelling factors for this revision was the discovery of male specimens of Sylviocarcinus devillei H. Milne Edwards, 1853, which would imply a relevant change in the systematics of the family (Magalhães and Türkay, 1996a).…”

“…In Brazil, currently, 35 species of freshwater prawns are known, belonging to three families: Atyidae, Euryrhynchidae and Palaemonidae (Magalhães et al, 2016). Among the Palaemonidae, 19 species of Macrobrachium Spence Bate, 1868 are known, which, besides being the most abundant genus (Mantelatto et al, 2016), is of great commercial interest.…”

Relative growth and population dynamics of Macrobrachium iheringi (Decapoda, Palaemonidae)

During the ontogenetic development of crustaceans, the relative growth of some structures may change, especially during the transition from juvenile to adult. This study describes the relative growth of body structures of Macrobrachium iheringi, and provides information on its population dynamics, such as structure, fecundity, and morphological sexual maturity. The sampling of M. iheringi was carried out in “Ribeirão da Hortelã”, in Botucatu (SP, Brazil). The length of the carapace (CL), abdomen (AL), and ischium (IL), merus (ML), carpus (CrL), propodus (PpL), and dactyl (DcL) of the second right pereopod were measured. In addition, the width of the second abdominal pleura (PW) and propodus height (PpH) were included in analyses. The relationships that best demonstrated the changes in the allometric coefficient were CL vs PpL in males and females. The CL, in which males and females reach morphological sexual maturity, was estimated as 13.3 mm and 11.1 mm, respectively. The sex-ratio differed from the expected 1:1 and was skewed towards females. Precipitation and temperature influenced the abundance of different demographic classes. Macrobrachium iheringi has few but large eggs, which is expected since this species has an abbreviated larval development. Based on these results, we conclude that the propodus are good indicators of the size at onset of morphological sexual maturity. In addition, important information was obtained on the biology of M. iheringi, including its life cycle pattern, reproduction and influence of abiotic factors.

“…Southern South America possesses a huge diversity of freshwater limnotopes; however, they are suffering rapid degradation (Magalhães, Campos, Collins, & Mantelatto, ; Pérez‐Losada et al, ). Although this region does have protected areas (PAs) of different categories integrated within national and international systems, the criteria used to identify these areas have sometimes conflicted or been applied opportunistically (Pressey, Humphries, Margules, Vane‐Wright, & Williams, ), as diverse and complex environmental, socio‐economic and political factors have influenced site designation (Whittaker et al, ).…”

1. The rapid degradation of freshwater habitats in southern South America may cause the extinction of the endemic species of Aegla, as well as other freshwater species and components of riverside environments related to them. Information on the distribution of species and their conservation status is essential for developing conservation strategies.2. The updated distribution of Aegla in its southernmost distribution was analysed in order to prioritize freshwater ecoregions, applying biogeographical, phylogenetic and conservation status and complementarity approaches. 3. The distributions of the species of Aegla were delineated on maps and plotted against freshwater ecoregions. A data matrix of areas versus species was constructed and a taxon-area cladogram was created. Ecoregions were ranked, based on their species richness and using a complementarity criterion, to create a list of those considered important for conservation. The conservation status of Aegla species was assessed on the basis of the categories and criteria of the International Union for Conservation of Nature (IUCN) to produce a decreasing order of the risk of species extinction. These assessments were combined to define a consensus ranking of the priority areas for conservation. 4. The areas of maximum species richness and endemicity, and consequently highest priority of conservation, were the Lower Parana and Patagonia ecoregions. The Cuyan Desaguadero and Mar Chiquita Salinas Grandes ecoregions were the areas of second priority, and the Chaco and Lower Uruguay ecoregions were the areas with the third priority for conservation. Ten out of the 20 species analysed fall within the threat categories of the IUCN. Sixty per cent of the species of Aegla analysed have at least one population contained in protected areas.5. The results obtained may be used to design strategies for implementing conservation policies on freshwater species, generate biogeographical atlases and contribute to selecting Ramsar sites.
