▪ Abstract Understanding the evolutionary processes that generate and sustain diversity in tropical faunas has challenged biologists for over a century should underpin conservation strategies. Molecular studies of within species relationships among species, when integrated with more traditional approaches biogeography paleoecology, have much to contribute this challenge. Here we outline current major hypotheses, develop predictions relevant molecular approaches, evaluate evidence, focusing...
The evolution of the amniotic egg was one great evolutionary innovations in history life, freeing vertebrates from an obligatory connection to water and thus permitting conquest terrestrial environments. Among amniotes, genome sequences are available for mammals birds, but not non-avian reptiles. Here we report sequence North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes highly syntenic with chicken microchromosomes, yet do exhibit high GC...
We developed an approach that combines distribution data, environmental geographic information system layers, niche models, and phylogenetic to investigate speciation processes. used Ecuadorian frogs of the family Dendrobatidae illustrate our methodology. For dendrobatids there are several cases for which is significant divergence allopatric parapatric lineages. The consistent pattern many related taxa or nodes exist in distinct space reinforces Lynch Duellman's hypothesis differential...
Sequences (644-681 bp) from the mitochondrial cytochrome b gene were obtained for 24 individuals representing geographic range and morphological diversity of polytypic salamander ring species Ensatina eschscholtzii. These data used to estimate phylogeny components test biogeographic scenario underlying current interpretations speciation in this complex. The analysis revealed high levels nucleotide variation among subspecies. Strong subdivision was evident within subspecies platensis...
Determining how ecological and evolutionary processes produce spatial variation in local species richness remains an unresolved challenge. Using mountains as a model system, we outline integrative research approach to evaluate the influence of mechanisms on generation maintenance patterns along among elevational gradients. Biodiversity scientists interested typically start by documenting at regional scales, based their knowledge taxon, environmental historical characteristics mountain...
Many biodiversity hotspots are located in montane regions, especially the tropics. A possible explanation for this pattern is that narrow thermal tolerances of tropical species and greater climatic stratification mountains create more opportunities climate-associated parapatric or allopatric speciation tropics relative to temperate zone. However, it unclear whether a general relationship exists among latitude, zonation ecology speciation. Recent taxon-specific studies obtained different...
Comparison of mitochondrial and morphological divergence in eight populations a widespread leaf-litter skink is used to determine the relative importance geographic isolation natural selection generating phenotypic diversity Wet Tropics Rainforest region Australia. The occur two geographically isolated regions, within each region, different habitats (closed rainforest tall open forest) that span well characterized ecological gradient. Morphological differences among ancient isolates...
We examine the effects of historical climate change on vertebrate differentiation in tropical rainforest by comparing phylogeographic patterns six species widespread rainforest‐restricted herpetofauna from throughout Wet Tropics Australia. Qualitative and quantitative comparisons structure reveal strikingly similar pre‐Pleistocene vicariant population either side a previously identified biogeographic break (variously referred to as Black Mountain Barrier or Corridor; BMC). While divergence...

We present evidence that a relatively widespread and common bat from South East Asia comprises two morphologically cryptic but acoustically divergent species. A population of the bicoloured leaf–nosed (Hipposideros bicolor) Peninsular Malaysia exhibits bimodal distribution echolocation call frequencies, with peaks in frequency maximum energy at ca. 131 142 kHz. The phonic types are genetically distinct, cytochrome b sequence divergence just under 7%. consider mechanisms by which acoustic...
Human-induced land use changes are causing extensive habitat fragmentation. As a result, many species not able to shift their ranges in response climate change and will likely need adapt situ changing conditions. Consequently, prudent strategy maintain the ability of populations is focus conservation efforts on areas where levels intraspecific variation high. By doing so, potential for an evolutionary environmental maximized. Here, we modeling approaches conjunction with variables model...
This empirically driven paper explores police presentational strategies on popular micro-blogging social media site Twitter. A total of 105,801 tweets from Canadian Toronto Police Service Twitter accounts were examined using qualitative document analysis. Thematic issues associated with professionalism and community policing are identified. finding that runs throughout each thematic includes official officer use while off duty. basic argument advanced herein is duty delineates the individual...
To better understand how environment shapes phenotypic and genetic variation, we explore the relationship between environmental variables across Ecuador morphological variation in wedge-billed woodcreeper (Glyphorynchus spirurus), a common Neotropical rainforest bird species. Generalized dissimilarity models show that amplified fragment length polymorphism markers was strongly associated with on both sides of Andes, but could also partially be explained by geographic distance western side...
The Old World tree frogs (Anura: Rhacophoridae), with 387 species, display a remarkable diversity of reproductive modes – aquatic breeding, terrestrial gel nesting, foam nesting and direct development. evolution these has until now remained poorly studied in the context recent phylogenies for clade. Here, we use newly obtained DNA sequences from three nuclear two mitochondrial gene fragments, together previously published sequence data, to generate well‐resolved phylogeny which determine...

Actor Evan Rachel Wood revealed 2022 documentary that she had been “essentially raped” Using qualitative media analysis, we collected and analyzed total 5466 user‐generated comments posted response to “Heart‐Shaped Glasses” video after publication Wood's...
