Dissection of preserved Atlantic coral snakes Micrurus corallinus, plus field data and histological analysis, provided information on male reproductive cycles. Testes are larger during autumn, when sperm production occurs, and smaller in spring, when spermatogenesis stops. The diameter of the distal deferent ducts is small in summer-autumn, when sperm are hardly found in the lumen, and it increases in winter-spring, when sperm is abundant, just prior to the mating season. Thus, the male cycle of ...

The swamp racer Mastigodryas bifossatus is a large colubrid snake distributed mainly in open areas in South America. Dissection of 242 specimens provided data on body sizes, sexual size dimorphism, reproductive cycles and food habits of this species. Adult M. bifossatus average approximately 1100 mm in snout-vent length, with males and females attaining similar sizes. Reproductive cycles in females seem to be continuous, although oviductal eggs occur mainly from the beginning to the middle of the ...

Abstract The reproduction and activity of Dipsas albifrons (Sauvage, 1884) from the southern Atlantic Forest, Brazil, were studied by analysing 144 preserved specimens. Females attained larger body sizes than males. Contrary to other Dipsadini of lower latitudes, reproduction in D. albifrons is seasonal with vitellogenesis and oviposition occurring in the rainy season and the hatching of the juveniles occurring at the end of the rainy season. Similar to other Dipsadini, clutch size in D. albifrons ...

We describe a new pitviper species, Bothrops alcatraz, of the Bothrops jararaca group, from Alcatrazes Island, off the coast of Sao Paulo, southeastern Brazil. It differs from the mainland coastal populations of B. jararaca in southeastern Brazil mostly by its darker coloration; smaller size; lower number of ventrals, subcaudals, and infralabials; number and shape of anterior cephalic scales; shape of hemipenis spines; intense coagulant activity of venom; and three specific venom proteins. From ...

We sought to study: 1) the impact of hemodynamic and left ventricular function on short-term postexercise blood pressure reduction in elderly hypertensive patients; and 2) the 22-h postexercise effects on ambulatory blood pressure in elderly hypertensive patients. Although early exercise provokes postexercise blood pressure reduction, the mechanisms underlying this response are not completely understood. Besides, it is unclear whether the reduction in blood pressure after exercise lasts long enough ...

Abstract The reproductive biology of the false coral snake, Oxyrhopus guibei, was studied through dissection of 496 specimens, combined with observations on captive individuals. Males mature with smaller body size than females, females attain much larger body size, and male-male combat is not expected. Clutch size ranged from 3 to 20, and was correlated with female length. Reproductive cycles in both males and females seem to be continuous, with vitellogenesis and spermatogenesis occurring throughout ...

Reproductive patterns are highly variable among Neotropical colubrids. Snakes of the Tribe Xenodontini are widely distributed in South America and show continuous reproductive cycles in many areas. We report interspecific and intraspecific variation in reproductive traits among these snakes and also show that seasonal cycles occur mainly in cooler areas. Clutch size relative to body size is similar among species, but Erythrolamprus spp. seem to lay fewer eggs than other species, and Waglerophis ...

Chronic exposure to ethanol may results in pathophysiologic changes in cellular function. The present work was designed to investigate the morphology of testis submitted to experimental ethanol ingestion. Experimental animals were divided into two groups. The control group (n = 23) received a solid diet and tap water and the alcoholic group (n = 23) received the same solid diet and ethanol P.A. diluted 20% in water (v/v). After 120 days of treatment, all animals were anesthetized, weighed and sacrificed. ...

Although Bothrops insularis is critically endangered, there is no estimate of its population size based on field quantifications. Here we provide the first estimate of its population size based on plot surveys conducted at the Queimada Grande Island. We distributed 26 quadrat plots regularly in a trail that crosses the island. Plots were sampled twice in 2002. Of the 26 plots we sampled, 21 were located in forests and five in grassy areas. For the first survey, mean estimates of population size ...

Neotropical snake assemblages present high species richness and complex structures. The Cerrado is the second largest biome in Brazil, and was included among the 25 World's biodiversity hotspots. In southeastern Brazil, the remnant Cerrado areas have suffered intense destruction, and presently less than 2% of Cerrado natural vegetation remain in São Paulo state. Virtually no detailed study on Cerrado snakes was carried out in this region. The Itirapina region has one of the last well preserved remnants ...

Previous studies indicate that (1) defensive displays are associated with habitat use in snakes, (2) visual defenses correlate better with habitat than with phylogeny, and (3) arboreal snakes are more exposed to predators than terrestrial species. We hypothesize that similar patterns exist for diurnal versus nocturnal snakes, and test these hypotheses against the occurrence of 13 defense types directed to visually oriented predators in 92 colubrids from two Neotropical assemblages, one from central ...

Abstract The morphometry and diet of two sympatric species of Chironius (C. flavolineatus and C. quadricarinatus) from Brazilian Cerrado are described. The two snake species differ in external morphology, as Chironius flavolineatus was the largest species (body, tail and eyes) whereas C. quadricarinatus the heaviest. Each species also showed marked sexual size dimorphism. In terms of dietary ecology, both species feed exclusively on frogs with a heavy preference for hylids and may have tendency to ...

A relatively large amount of variation occurs in the reproductive ecology of tropical snakes, and this variation is generally regarded as being a consequence of seasonality in climate and prey availability. In some groups, even closely related species may differ in their reproductive ecology; however, in others it seems to be very conservative. Here we explore whether characters related to reproduction are phylogenetically constrained in a monophyletic group of snakes, the subfamily Dipsadinae, ...

Software developers spend considerable effort implementing auxiliary functionality used by the main features of a system (e.g., compressing/decompressing files, encryption/decription of data, scaling/rotating images). With the increasing amount of open source code available on the Internet, time and effort can be saved by reusing these utilities through informal practices of code search and reuse. However, when this type of reuse is performed in an ad hoc manner, it can be tedious and error-prone: ...

Abstract Mahogany is one of the most valuable woods and was widely used until it was included in Appendix II of the Convention on International Trade in Endangered Species as endangered species. Mahogany wood sometimes is traded under different names. Also, some similar woods belonging to the Meliaceae family are traded as “mahogany” or as being of a “mahogany pattern”. To investigate the feasibility of the use of near infrared spectroscopy for wood discrimination, the mahogany ( Swietenia macrophylla ...
