Relationships among lizards of the anole genera Chamaeleolis, Chamaelinorops, Phenacosaurus, and Anolis (sensu lato) are discussed based upon a cladistic analysis osteological, karyological, albumin immunological data. Osteological data support sister-group relationship carolinensis subsection beta section anoles, while anoles bimaculatus-tatellus-cybotes, cuvieri series, latifrons series sequentially more distantly related to terminal cluster. Karyological five major groupings. One these...

Reptiles and amphibians constitute a significant portion of vertebrate biomass in terrestrial ecosystems may be important arbovirus reservoirs. To investigate mosquito preference for ectothermic hosts, feeding indices were calculated from data collected Tuskegee National Forest, Alabama, USA. Four species fed upon with Culex peccator Cx. territans primarily ectotherms. These two appeared to target distinct little overlap host choice. was generalist its patterns within ectotherms, more...

The concept of optimal size has been invoked to explain patterns in body terrestrial mammals. However, the generality this phenomenon not tested with similarly complete data from other taxonomic groups. In study we describe three statistical snakes, all which indicate an length 1.0 m. First, a distribution largest lengths 618 snake species had single mode at Second, found positive relationship between member island assemblage and area negative smallest area. Best-fit lines through these...

Three null models have been proposed to predict the relative frequencies of topologies phylogenetic trees. One model assumes each distinguishable n-member tree is equally likely (proportional-to-distinguishable-arrangements model). A second that topological type (equiprobable third probability determined by random speciation (Markov We sampled published trees from three major groups organisms: division Angiospermae, class Insecta, and superclass Tetrapoda. Our sampling was more restricted...

Determining the structure of ectoparasite-host networks will enable disease ecologists to better understand and predict spread vector-borne diseases. If these have consistent properties, then studying well-understood could lead extrapolation properties others, including those that support emerging pathogens. Borrowing a quantitative measure network from studies mutualistic relationships between plants their pollinators, we analyzed 29 ectoparasite-vertebrate host networks--including three...

The concept of food limitation has played a key role in the theoretical framework population and community ecology, especially for anoline lizards. A common hypothesis is that limited island anoles but relatively unlimited mainland anoles.

Mark—recapture data were collected on control experimental plots over 9—mo pretest 7—mo test period during which...

In this study I investigated how individuals of Norops humilis at a tropical lowland wet—forest site in Costa Rica used energy made available by supplemental feeding. manipulated prey availability on three experimental plots attracting arthropods to bits rotting meat that were replenished weekly. Each plot was paired with an unmanipulated control block design. Mark—recaputre data collected all over 7—mo test period during which 9910 observations 1582 individuals.

Seasonal shifts in host use by mosquitoes from birds to mammals drive the timing and intensity of annual epidemics mosquito-borne viruses, such as West Nile virus, North America. The biological mechanism underlying these has been a matter debate, with hypotheses falling into two camps: (1) shift is driven changes abundance, or (2) seasonal foraging behavior mosquitoes. Here we explored idea that are temporal patterns reproduction. We investigated relationship between reproductive phenology...

The ecological restoration of fire-suppressed habitats may require a multifaceted approach. Removal hardwood trees together with reintroduction fire has been suggested as method restoring longleaf pine (Pinus palustris) forests; however, this strategy, although widespread, not evaluated on large spatial and temporal scales. We used landscape-scale experimental design to examine how bird assemblages in sandhills responded alone or following mechanical removal herbicide application reduce...

Habitat loss and degradation are thought to be the primary drivers of species extirpations, but for many we have little information regarding specific habitats that influence occupancy. Snakes conservation concern throughout North America, effective management hindered by a lack basic natural history small number large-scale studies designed assess general population trends. To address this gap, compiled detection/nondetection data 13 large terrestrial from 449 traps located across...

Eastern equine encephalitis virus (EEEV) is among the most medically important arboviruses in North America, and studies suggest a role for amphibians reptiles its transmission cycle. Serum samples collected from 351 (27 species) Alabama, USA, were tested presence of antibodies against EEEV. Frogs, turtles, lizards showed little or no seropositivity, snakes had high seropositivity rates. Most seropositive species preferred abundant hosts Culex spp. mosquitoes at Tuskegee National Forest,...

ABSTRACT Length-mass relationships within an assemblage of tropical snakes are used to describe morphological groups. We report patterns body size based on length and mass measurements 603 individual 27 species captured at La Selva, Costa Rica from March 1982 through August 1984. This is composed least four groups each which consists with similar habitat preferences. These heavy-bodied terrestrial forms, light-bodied arboreal long-tailed leaf-litter forms unextreme relative tail length....

Landscape composition and configuration affect ecological processes at the population community levels, but few studies have demonstrated effects of landscape pattern on individuals. Because heterogeneity influences abundance distribution critical resources, it is hypothesized that indirectly affects home range size To examine spatial ecology declining Eastern Diamond-backed Rattlesnake (Crotalus adamanteus; EDB), we conducted a two-year study in southwestern Georgia. We obtained estimates...

Krysko et al. (2016a) used analyses of DNA sequence data to reveal two genetic lineages Drymarchon couperi. The Atlantic lineage contained specimens from southeastern Georgia and eastern peninsular Florida, the Gulf Coast western southern Florida as well Alabama, Mississippi. In a second paper (2016b) analyzed morphological variation lineages, which allowed them restrict D. couperi describe new species, kolpobasileus. This taxonomic discovery was remarkable for such large, wide-ranging...
