“…3. Cladogram adapted from Tonini et al (2016) showing the degree to which snake species are more sensitive (positive effect sizes) or less sensitive (negative effect sizes) to human land use. Also shown for each species is its primary prey type (Vertebrate or Invertebrate) and Aquatic index (proportion of aquatic habitats used by each species out of all habitats listed in IUCN RedList species accounts).…”

a b s t r a c t a r t i c l e i n f oUnderstanding how traits affect species responses to threats like habitat loss may help prevent extinctions. This may be especially true for understudied taxa for which we have little data to identify declines before it is too late to intervene. We used a metric derived from citizen science data on snake occurrences to determine which traits were most correlated with species' sensitivity to human land use. We found that snake species that feed primarily on vertebrates, that use a high proportion of aquatic habitats, and that have small geographic ranges occurred in more natural and less human-dominated landscapes. In contrast, body size, clutch (or litter) size, the degree of exposure to human-dominated landscapes, reproductive mode, habitat specialization, and whether a species was venomous or not had less effect on their sensitivity to human land use. Our results extend previous findings that higher trophic position is correlated with extinction risk in many vertebrates by showing that snake species that feed primarily on vertebrates are more sensitive to human land use -a primary driver of extinction. It is likely that conversion of natural landscapes for human land use alters biotic communities, causing losses of important trophic groups, especially in aquatic and riparian communities. Practitioners should therefore prioritize preserving aquatic habitat and natural landscapes with intact biotic communities that can support species at higher trophic levels, as well as focus monitoring on populations of range-restricted species.

“…Hence, following the approach of Doody (2009), we plotted the available information in a phylogenetic tree of all currently recognized phyllodactylid genera, in order to visualize the macroevolutionary patterns of this behavior. We used the most recent Squamate phylogenetic estimate (Tonini 2016), and pruned the tree so it would only depict the relationships among phyllodactylid genera, using the package (Paradis 2004) in R version 3.3.1 (R Core Team 2016).…”

“…Phylogenetic relationships among currently recognized genera of Phyllodactylidae (number of species know to nest communally/ number of species in the genus). Tree adapted from Tonini et al (2016). Genera known to lay eggs communally are in black, and genera for which no evidence of communal nesting is available are in gray.…”

Nesting in the lizard Phyllopezus pollicaris (Squamata: Phyllodactylidae) and a phylogenetic perspective on communal nesting in the family. Communal nesting occurs in many reptile species. The hypotheses that explain the evolution of such behaviours are still controversial, but will be better understood as more communal nesting records are a communal nesting record for squamate species in a Cerrado core area. We provide nest photographs and detailed neonate measurements and weight. Nests were found during the dry season, in contrast with the reproduction pattern previously described for the species in the Cerrado periphery. We also conducted an extensive literature review seeking all available information on communal nesting information in Phyllodactylidae, and present this information in the context of a phylogenetic tree of phyllodactylid genera. We suggest that studying the correlation between communal nesting evolution and reproductive available in the literature. Keywords

“…Recent efforts to understand the global tree of 248 life have improved substantially our understanding of relationships among genera and species (Hinchliff 249 et al, 2015). For instance, recent phylogenies of birds (Jetz et al, 2012), mammals (Faurby & Svenning,250 2015a) and squamate reptiles (i.e., lizards and snakes) (Tonini et al, 2016) purport to include all living 251 species. However, a substantial fraction of the species included in these studies was placed within the 252 phylogeny solely based on morphological features due to the lack of genetic data.…”

Despite major advances in the generation of biodiversity data, many 46 questions remain to be answered. In this review, we first summarize some of the knowns and unknowns 47 about Neotropical biodiversity, and discuss how human impact may have drastically affected some of the 48 patterns observed today. We then link biodiversity to landscape, and outline major advances in 49 biogeographical research. In particular, we argue that it is crucial to test the effect of landscape and 50 climatic evolution to biotic diversification and distribution in order to achieve a comprehensive 51 understanding of current patterns. In this context, it is also important to consider extant and extinct taxa, 52 as well as to use probabilistic and parametric methods that explicitly include landscape evolution models.
