Watson-Crick conjugates of words and languages [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
In this work, we explore the concept of Watson-Crick conjugates, also known as $θ$-conjugates (where $θ$ is an antimorphic involution), of words and languages.

Reproductive activity of anurans in a dominant agricultural landscape from central-eastern Argentina

open access: yesRevista Mexicana de Biodiversidad, 2013
Agriculture can modify natural systems through habitat loss and fragmentation, as well as through the effect of agrochemicals on biological traits such as reproduction.

Anuran swingers: misdirected mating attempts occurred early during anuran diversification

open access: yesBiological Journal of the Linnean Society, 2023
Abstract Promiscuity, explosive breeding and male-biased operational sex-ratios can affect the strength of male selectivity and may play major roles in the expression of misdirected matings (with conspecific males, other species, corpses or objects) in anuran amphibians.

Development and characterization of novel microsatellite loci in the native tree frog species, Polypedates braueri and cross-species amplification in the alien species, P. megacephalus, in Taiwan [PDF]

open access: yesBiodiversity Data Journal
Polypedates megacephalus is an alien species first recorded in 2006 in Taiwan. The expanding population of P. megacephalus poses potential threats to the native frog species, especially to the closely-related species P. braueri.

Brain regeneration in anuran amphibians [PDF]

open access: yesDevelopment, Growth & Differentiation, 2007
Urodele amphibians are highly regenerative animals. After partial removal of the brain in urodeles, ependymal cells around the wound surface proliferate, differentiate into neurons and glias and finally regenerate the lost tissue. In contrast to urodeles, this type of brain regeneration is restricted only to the larval stages in anuran amphibians ...

Basidioboliasis in Anurans in Florida [PDF]

open access: yesJournal of Wildlife Diseases, 2002
Members of the genus Basidiobolus, a saprophytic fungus, have been associated with the digestive tracts of a wide variety of amphibians and reptiles. To elucidate the relationship of Basidiobolus sp. with amphibians in central Florida (USA), we document the occurrence of the fungus in the digestive tracts of Bufo terrestris, Buffo quercicus, Hyla ...

Identification key for anuran amphibians in a protected area in the northeastern Atlantic Forest

open access: yesPapéis Avulsos de Zoologia, 2021
The identification of anuran amphibians is still a challenge in megadiverse assemblages. In the Neotropics, the Atlantic Forest harbors more than 600 anuran species, and many studies in this ecoregion report anuran assemblages surpassing 30 species ...

The relationship between pond habitat depth and functional tadpole diversity in an agricultural landscape [PDF]

open access: yesRoyal Society Open Science, 2015
One of the most important goals of biodiversity studies is to identify which characteristics of local habitats act as filters that determine the diversity of functional traits along environmental gradients. In this study, we investigated the relationship

Sexual size dimorphism in anurans [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2002
Several hypotheses have been proposed to explain the direction and extent of sexual size dimorphism in anurans (in which males are usually smaller than females) as a result of sexual selection. Here, we present an analysis to test the hypothesis that sexual dimorphism in anurans is largely a function of differences between the sexes in life-history ...

Tree cover and habitat type mediate taxonomic and phylogenetic anuran diversity in Southeastern Peru

open access: yesGlobal Ecology and Conservation
Understanding the drivers that shape anuran diversity is crucial for identifying conservation hotspots, particularly as global anuran declines threaten the reduction of their ecosystem functions across food chains.
