Fecundity of the mangrove crab Ucides cordatus (Linnaeus, 1763) (Brachyura, Ocypodidae)

Females of the mangrove crab Ucides cordatus were collected in a monthly basis along a 2-year period at the mangrove areas of Iguape, SP, Brazil. Ovigerous individuals were measured (CW, carapace width) and weighed (WW, wet weight). Each brood was weighed (WWE, wet weight of eggs), dried (DWE, dry weight of eggs) and the number of eggs (EN) was recorded. Scatter plots for the relationships EN/CW, EN/WW and EN/WWE were produced, and the data were subjected to regression analysis. Relative average fecundity (F 1) was calculated in different seasons and compared to verify if there were any temporal variation of reproductive intensity. Fecundity in U. cordatus varied from 36.081 to 250.566 eggs according to the size-dependent relationship EN = 15.27CW 2.24 (N = 66; R 2 = 0.69; p<0.001). The other expressions obtained for the relationships were: EN = 3797.6WW 0.813 (N = 56; R 2 = 0.72; p<0.001); EN = 29226WWE 0.775 (N = 54; R 2 = 0.70; p<0.001); and EN = 1093586DWE 0.769 (N = 66; R 2 = 0.86; p<0.001). Ovigerous females were found only during spring and summer, and relative average fecundity differed between these seasons. Relative average fecundity was higher in spring and relative frequency of ovigerous females was higher during summer. Overall reproductive intensity was similar between these seasons. The observed trends are regarded to be related to temperature and photoperiod variations.

Relative growth of the mangrove crab Ucides cordatus (Linnaeus, 1763) (Crustacea, Brachyura, Ocypodidae) at Iguape, São Paulo, Brazil

A total of 2,130 individuals of Ucides cordatus (1,255 males and 875 females) were captured in a mangrove forest at Iguape, São Paulo, Brazil. For each crab, the following body structures were measured: carapace (width = CW; length = CL; depth = CD), 5th abdominal somite (AW), major chelar propodus (length = PL; width = PW; depth = PD), and 1st and 2 nd gonopod pairs (length = GL1 and GL2). The Student t and Snedecor F tests were used to verify any changes in growth allometric rates during ontogeny. The relationships CLxCW, PLxCW (for both sexes), GL1xCW and GL2xCW (males) and AWxCW (females), showed a better fit by two equations for the juvenile and adult phases (p<0.01). The inflexion point size between regression lines, indicated by each morphometric relationship, allowed to propose four morphotypes for U. cordatus. Males were classified in juvenile (CW le; 32 mm), pre-puberty (32 ≤ CW ≤ 51 mm), sub-adult (51 ≤ CW ≤ 59 mm) and adult (CW > 59 mm). Females showed a similar size interval: (juvenile CW ≤ 39 mm, pre-puberty 39 ≤ CW ≤ 53 mm, sub-adult 53 ≤ CW ≤ 58 mm, adult CW > 58 mm).

Pelvimetria em macacos-da-noite (Aotus azarai infulatus - KUHL, 1820)

Related data to the diameters of the pelvis from 72 Aotus azarai infulatus, owl monkeys, 42 adult males and 30 adult non-pregnant females, were obtained in vivo by ventrodorsal projection radiographic exams, correlated with sex, the measures of the body and their origin. The mean values of the body length (30.94 cm), tail length (35.63 cm), thoracic perimeter (18.97 cm), hip perimeter (17.11 cm) and the weight (0.96 Kg) were verified. The radiographic images were digitalized and measured, and the mean values were 1.41 cm for the superior biiliac diameter; 1.58 cm for the inferior biiliac diameter; 1.97 cm for the medium biiliac diameter; 2.64 cm for the right diagonal diameter; 2.66 cm for the left diagonal diameter; 2.48 cm for the sacrum-pubic diameter; 3.85 cm 2 for the inlet pelvic area. In conclusion, the pelvis from males and females Aotus azarai infulatus can be classified as dolicopelvic and there is pelvic sexual dimorphism in adult owl monkeys (Aotus azarai infulatus).

Anatomia do nervo isquiático em mocós (Kerodon rupestris WIED, 1820) aplicada a clínica de animais silvestres

To know the origin of the ischiatic nerve in mocos (Kerodon rupestris Wied,1820) near by intervertebral forames and the muscling belonging to its routes were used 10 adult animals, from CEMAS-ESAM. After natural obit, they were fixed in formol (10%) and dissected to exposition and to singt of the ischiatic nerve. The results were indicated in percentage. Variations in the quantity of the lumber and sacral vertebras nere observed, five animals (50,00%) reveled seven lumbar vertebras and three sacral ones; two animals recrealed seven lumbar vertebras and four sacral ones, and two animals reveled six lumbar vertebras and three sacral ones. An animal (10,00%) revealed six lumbar vertebras and four ones. Therefore, the origin of the nerve was differentiated five animals (50,00%) had the participation of L 7,S 1,S 2; two animals (20,00%) with L 7,S 1; and a little part of S 2. Two animals (20,00%) with L 6,S 1,S 2, and an animal (10,00%) with L 6,S 1, and a little part of S 2. The last root of the ischiatic nerve in all its origins, contribute to the constitution of the first root of pudental nerve. It was verified that in all its route, the ischiatic nerves (100,00%) ceded branches to the muscles: medial gluteus, deep gluteus, superficial gluteus, emiting muscular branches to the femoral biceps or to thigh, and to the semimembranous and semi-tendinous muscles, that is continuous with a high calibre trunk, originating the fibular nerve(sideways), the tibial nerve(medial) and the lateral plantar sural cutaneous nerve (caudal).
