Abstract The Golden Lancehead (Bothrops insularis) is a critically endangered snake endemic to the Queimada Grande Island in southeastern Brazil. Here, we provide data on reproductive biology of B. insularis obtained in the field and from preserved museum specimens and compare our results with its mainland relative Bothrops jararaca. Similar to other Bothrops species, females of B. insularis attained larger body sizes than males, but the sexual size dimorphism (SSD) value is much lower than in… 
Annual changes in seminal variables of golden lanchead pitvipers (Bothrops insularis) maintained in captivity.
TLDR
Sperm concentration in all individuals was less during the winter, but no seasonal fluctuations were detected in semen volume, of particular importance to the development of reproductive tools such as male selection, artificial insemination and sperm freezing for the genetic management of this critically endangered snake.
Reproductive and feeding biology of the common lancehead Bothrops atrox (Serpentes, Viperidae) from central and southwestern Brazilian Amazonia
TLDR
The pitviper Bothrops atrox is a widely distributed and medically important snake in Amazonia and there was an ontogenetic shift in the diet: smaller individuals fed mainly on ectothermic prey, while adults tended to incorporate endothermac prey (mammals) to their food repertoire.
Reproduction in the pitviper Bothrops jararacussu: large females increase their reproductive output while small males increase their potential to mate.
TLDR
The results and previous literature collectively suggest that, in Bothrops, the evolution of SSD is driven by fecundity selection, variation in reproductive output is influenced by variation in female body size, and the timing of spermiogenesis is influences by other factors in addition to temperature.
Reproductive Biology of Bothrops atrox (Serpentes, Viperidae, Crotalinae) from the Brazilian Amazon
TLDR
Results show that B. atrox from Amazonia has a unique reproductive strategy (for each sex) among pit vipers, indicating greater reproductive plasticity when compared with its congeners.
First record of mating of Bothrops insularis (Serpentes: Viperidae) in nature, with comments on sexual behavior
TLDR
The first record of mating of B. insularis in the wild is provided, corroborating the observations made by Amaral (1921), who reported copulations in captivity in winter (August-September) and during the daytime.
Genetic variability, management, and conservation implications of the critically endangered Brazilian pitviper Bothrops insularis
TLDR
It is recommended that the genetic data support researches as a base to maintain a viable and healthy captive population, highly genetically similar to the in situ one, which is crucial for considering a reintroduction process into the island.
Extinction Risk Evaluation and Population Size Estimation of Bothrops insularis (Serpentes: Viperidae), a Critically Endangered Insular Pitviper Species of Brazil
Abstract. The golden lancehead pitviper (Bothrops insularis) is a critically endangered species endemic to the Queimada Grande Island, a federally protected area located 33 km off the southern coast
Population Dynamics of the Critically Endangered Golden Lancehead Pitviper, Bothrops insularis: Stability or Decline?
TLDR
Survival was slightly higher in the wet season than in the dry season, and temporal emigration was high, indicating the importance of accounting for this parameter both in the sampling design and modeling.
Another new and threatened species of lancehead genus Bothrops (Serpentes, Viperidae) from Ilha dos Franceses, Southeastern Brazil.
TLDR
The new insular species of the genus Bothrops is described from Ilha dos Franceses, a small island off the coast of Espírito Santo State, in southeastern Brazil, being nocturnal, semiarboreal, and feeding on small lizards and centipeds.
Morphology and seasonality of the sexual segment of the kidney in genus Bothrops snakes
TLDR
The morphology of SSK in various species of the pitviper‐genus Bothrops, a medically relevant clade of Neotropical snakes, is investigated using histology, histochemistry, as well as scanning and transmission electron microscopy to evaluate the relationship ofSSK hypertrophy with spermatogenesis and storage of sperm.

A NEW INSULAR SPECIES OF PITVIPER FROM BRAZIL, WITH COMMENTS ON EVOLUTIONARY BIOLOGY AND CONSERVATION OF THE BOTHROPS JARARACA GROUP (SERPENTES, VIPERIDAE)
TLDR
The dwarfism and characteristics of venom in B. alcatraz may be related to its diet (similar to that of juveniles of the mainland B. jararaca) and the new species is regarded as critically endangered due to its very small area of occurrence and the declining quality of its habitat.
Comparative Ecology of Three Australian Snake Species of the Genus Cacophis (Serpentes: Elapidae)
TLDR
Dissections of 550 museum specimens yielded data on food habits, body sizes, sexual size dimorphism, mode of reproduction, clutch sizes, growth rates and seasonal schedules of reproduction of the elapid snake genus Cacophis.
Morphological correlates of incipient arboreality and ornithophagy in island pitvipers, and the phylogenetic position of Bothrops insularis
TLDR
Morphological differences between two semi-arboreal, bird-eating island pitvipers, Bothrops insularis and Gloydius shedaoensis, and their mainland relatives were investigated, suggesting that caution is required when interpreting character state shifts coinciding with ecological shifts in a single species only.
The golden lancehead Bothrops insularis (Serpentes: Viperidae) relies on two seasonally plentiful bird species visiting its island habitat
TLDR
It is suggested that one cause may be that these birds forage mostly on vegetation, and thus cause the snakes to search for prey on this arboreal substratum.
