1. Morphological sexual maturity of the freshwater anomuran crab Aegla parana (Crustacea, Decapoda, Aeglidae) from Negro River Sub-basin, Upper Iguaçu Basin, southern Brazil
RESUMO O comprimento da carapaça (CL) no início da maturidade sexual morfológica (MSM) em Aegla paranaSchmitt, 1942foi estimado em uma população que ocorre na Sub-bacia do Rio Negro, Bacia do Alto Iguaçu, sul do Brasil. Os animais foram capturados com rede Surber e com armadilhas iscadas no Rio Negro e no seu afluente Rio Totó, em dezembro/2017, junho

2. Ludwig Buckup’s academic life and his contribution to Carcinology
Abstract Ludwig Buckup holds a Bachelor’s degree in Natural History in 1954 from the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, and a Ph.D. in Zoology from the University of Tübingen, Germany, in 1958. He joined UFRGS as a Professor in 1958, from where he retired in 1990. During this period he was fully devoted to his career of profess

3. Allometry and sexual dimorphism of the Neotropical freshwater anomuran Aegla marginata Bond-Buckup & Buckup, 1994 (Crustacea, Anomura, Aeglidae)
Abstract This study analyzes ontogenetic allometry in Aegla marginata Bond-Buckup & Buckup, 1994, a freshwater crustacean, in order to evaluate the growth pattern and the presence of sexual dimorphism, using a multivariate approach. The specimens were sampled from streams in Intervales State Park, São Paulo State, Brazil. For each specimen, we measured the

4. Diversity and conservation status of Aegla spp. (Anomura, Aeglidae): an update
Abstract The speciose genus Aegla Leach, 1820 is the only valid extant genus of the anomuran family Aeglidae, bearing 83 known species. This diversity may be even greater since there is some evidence for cryptic speciation. The genus is endemic to southern South America, occurring in freshwater habitats. We assessed the conservation status of 82 species of A

5. Allometric growth, sexual maturity and reproductive cycle of Aegla castro (Decapoda: Anomura: Aeglidae) from Itatinga, state of São Paulo, southeastern Brazil
Abstract Allometric growth of chelae dimensions was analyzed to assess the average size at the onset of morphometric maturity (ASOMM) and sexual dimorphism regarding the pair of chelae in the Aegla castro. Both adult males and females are heterochelous with the most robust chela occurring predominantly on the left side. Both chelae are larger in males than t

6. Growth, sexual maturity and sexual dimorphism of Aegla georginae (Decapoda: Anomura: Aeglidae) in a tributary of the Ibicuí River in southern Brazil
ABSTRACT This study aimed to estimate the growth and size at the onset of sexual maturity in a population of Aegla georginae . Specimens were sampled from November 2007 to October 2008 in the Perau Creek (Ibicuí-Mirim sub-basin; Uruguay River basin). All captured specimens were sexed, and their cephalothoracic length (CL), minor and larger propodi length (M

7. Método de captura e estrutura populacional de Aegla georginae Santos and Jara, 2013 (Decapoda: Anomura: Aeglidae) em um afluente do rio Ibicuí no sul do Brasil
Resumo No presente estudo, nós investigamos aspectos populacionais de Aegla georginae na Bacia do rio Ibicuí e consideramos a implicação de diferentes métodos de captura na análise dos dados de dinâmica populacional. Foram amostrados 1774 indivíduos: 1259 machos (21 e 97 juvenis e 1028 e 113 adultos em armadilhas e rede de mão, respectivamente), e 5

8. Shape and size variations of Aegla uruguayana (Anomura, Aeglidae) under laboratory conditions: A geometric morphometric approach to the growth
Crustacean growth studies typically use modal analysis rather than focusing on the growth of individuals. In the present work, we use geometric morphometrics to determine how organism shape and size varies during the life of the freshwater crab, Aegla uruguayana Schmitt, 1942. A total of 66 individuals from diverse life cycle stages were examined daily and e

9. Population biology of Aegla platensis (Decapoda: Anomura: Aeglidae) in a tributary of the Uruguay River, state of Rio Grande do Sul, Brazil
Aeglids are freshwater anomurans that are endemic from southern South America. While their population biology at the species-level is relatively well understood, intraspecific variation within populations has been poorly investigated. Our goal was to investigate the population biology of Aegla platensis Schmitt, 1942 from the Uruguay River Basin, and compare

11. New species and records of the genus Aegla Leach, 1820 (Crustacea, Anomura, Aeglidae) from the West-Central region of Rio Grande do Sul, Brazil
Aeglidae are anomuran freshwater "crabs" found only in southern South America. In Brazil, the greatest species diversity occurs in hydrographic basins of the state of Rio Grande do Sul. Two new species, Aegla georginae and Aegla ludwigi, are described from the Ibicuí and Ijuí Rivers, respectively (Uruguay River Basin). The new taxa can be distinguished fro

12. Descrição da morfologia externa dos jovens recém-eclodidos de Aegla paulensis Schmitt, 1942 e de Aegla perobae Hebling &Rodrigues, 1977 (Crustacea, Decapoda, Aeglidae) / Description of the external morphology of the newly-hatched juveniles of Aegla paulensis Schmitt, 1942 and Aegla perobae Hebling &Rodrigues, 1977 (Crustacea, Decapoda, Aeglidae)
O gênero Aegla Leach, 1820 representa o único táxon dentro de Decapoda Anomura com representantes adaptados exclusivamente a ambientes de água doce. As eglas são endêmicas da América do Sul e vivem em ambientes lóticos com alto nível de oxigenação. Estudos comparativos da morfologia de jovens recém-eclodidos podem contribuir para estabelecer rela
