Revisão taxonômica do grupo limata de Crematogaster Lund, 1831 (Formicidae: Myrmicinae: Crematogastrini)

O gênero Crematogaster é um grupo diverso, com características peculiares e taxonomia complexa. Cerca de 780 espécies e subespécies foram descritas para este gênero, e constantes mudanças são feitas ao longo do tempo devido a sua ampla distribuição geográfica e variedade morfológica. Poucas revisões foram feitas para este gênero, sendo, as existentes, feitas com fauna regional. Neste trabalho, foi feita a revisão taxonômica do grupo de espécies Crematogaster limata, onde foram redescritas sete espécies: Crematogaster brasiliensis Mayr, 1878, C. carinata Mayr, 1862, C. levior Longino, 2003, C. limata Smith, 1858, C. longispina Emery, 1890, C. tenuicula Forel, 1904 e quatro novas espécies foram descritas: Cremastogaster sp. nov. 1, Cremastogaster sp. nov. 2, Crematogaster sp. nov. 3, Crematogaster sp. nov. 4. A variedade Crematogaster longispina var. boliviana foi elevada à categoria de espécie e redescrita. Mapas de distribuição geográfica para todas as espécies e uma chave de identificação específica baseada em operárias são apresentados.

Morphology of the male agouti accessory genital glands (Dasyprocta prymnolopha Wagler, 1831)

The morphology of the accessory genital glands of the male agouti was studied in twenty-three animals that were raised in captivity. Twenty animals had their genital glands dissected in situ for macroscopic description. The samples of each gland were recovered, embedded in paraffin, sliced and stained by Hematoxylin-Eosin technique. It was founded four pairs of glands: the vesicular glands, the coagulating glands, the prostate and the bulbourethral glands. Histological characteristics of the vesicular, coagulating and prostate glands showed similar morphology, within the pseudostratified columnar epithelium. The tubulo-alveolar type of the bulbourethral glands showed a lack of connective tissue among the tubules, a small amount of red stained presented it the cytoplasm, and the presence of vacuoles in the tissue. This study concluded that the agouti showed to have similar morphological aspect described in the others species of rodents.

Arterial supply of the penis in agoutis (Dasyprocta prymnolpha, Wagler, 1831)

The arterial vascularization of agoutis` penis (Dasyprocta prymnolopha) were analysed using ten male adults from `Nucleo de Estudos e Preservacao de Animais Silvestres da Universidade Federal do Piaui` (FUFPI/IBAMA n degrees 02/99). Among the total number of specimens, six animals had natural death and were members of the research collection of the Laboratory of Anatomy, and four were killed after anaesthesia. Stained bi-centrifugated-Cis-I-4 latex was injected in arterial vessels responsible for penis vascularization throughout the abdominal portion of aorta. The samples were fixed in 10% formaldehyde solution and arteries were dissected. The penile artery is originated as a branch of internal pudendal artery. At the level of ischiatic arch, the penile artery project two branches, the penile dorsal and the deep arteries; those arteries irrigates the penile dorsal surface and the corpus cavernosum penis. The penile dorsal arteries have an independent course up to the glans penis. Based on the conditions of this work a remarkable similarity regarding the distribution of vessels destined to the agouti penis when compared to other domestic, wild and lagomorph rodents as rabbits.

Reproductive dynamics of Sterna hirundinacea Lesson, 1831 in Ilha dos Cardos, Santa Catarina, Brazil

In this work, we intend to describe the reproductive dynamics of Sterna hirundinacea in an island fromSouth Brazil.We studied the reproductive biology of this species in its natural environment and provide data on their growth, survival, and reproductive success in Ilha dosCardos, SantaCatarina, South Brazil. Samplingswere carried out daily on the island throughout the reproductive seasons of 2003, 2005, and 2006 and the different stages of development of the chicks were characterized according to age, length of the beak, and plumage characteristics.We provide a basic equation Lm = 167.91 (1 – e −0.062t−(−0.23)) to determine the approximate age of individuals using their body mass. The main cause of chick mortality on the island was natural (63.17% in 2003, 81.41% in 2005, and 79.96% in 2006), whereas predation contributed to mortality in a proportion of 38.83% in 2003, 18.59% in 2005, and 20.04% in 2006.The absence in the area of the chicks’ main predator, Kelp gull (Larus dominicanus), the large number of chicks that reached the final stages of development, and their reproductive success demonstrate that Ilha dos Cardos is an important breeding site for the species in southern Brazil.
