| drought reduces chytrid fungus (batrachochytrium dendrobatidis) infection intensity and mortality but not prevalence in adult crawfish frogs (lithobates areolatus). | to fully understand the impacts of the chytrid fungus batrachochytrium dendrobatidis (bd) on amphibians it is necessary to examine the interactions between populations and their environment. ecologic variables can exacerbate or ameliorate bd prevalence and infection intensity, factors that are positively related when bd is acting on naive amphibian populations as an epidemic disease. in crawfish frogs (lithobates areolatus), a north american species with a complex life history, we have shown tha ... | 2014 | 24171560 |
| seasonal pattern of batrachochytrium dendrobatidis infection and mortality in lithobates areolatus: affirmation of vredenburg's "10,000 zoospore rule". | to fully comprehend chytridiomycosis, the amphibian disease caused by the chytrid fungus batrachochytrium dendrobatidis (bd), it is essential to understand how bd affects amphibians throughout their remarkable range of life histories. crawfish frogs (lithobates areolatus) are a typical north american pond-breeding species that forms explosive spring breeding aggregations in seasonal and semipermanent wetlands. but unlike most species, when not breeding crawfish frogs usually live singly--in near ... | 2011 | 21423745 |
| antimicrobial peptides and protease inhibitors in the skin secretions of the crawfish frog, rana areolata. | the dorsal skin of the crawfish frog, rana areolata, is associated with numerous prominent granular glands. proteomic analysis of electrically stimulated skin secretions from these glands enabled the identification and characterization of eight peptides with antimicrobial and hemolytic activity belonging to the previously identified brevinin-1, temporin-1, palustrin-2, palustrin-3, esculentin-1 (two peptides), and ranatuerin-2 (two peptides) families. the primary structures of the peptides were ... | 2002 | 12429503 |
| antimicrobial peptides from the skin secretions of the new world frogs lithobates capito and lithobates warszewitschii (ranidae). | taxonomic revisions within the anuran family ranidae have established the genus lithobates that currently comprises 49 species of frogs from the new world. peptidomic analysis, using reversed-phase hplc with on-line detection by electrospray mass spectrometry, has led to the identification of multiple antimicrobial peptides in norepinephrine-stimulated skin secretions of the north american frog lithobates capito and the central american frog lithobates warszewitschii. structural characterization ... | 2009 | 19635516 |

| asymmetric competition in larval amphibian communities: conservation implications for the northern crawfish frog, rana areolata circulosa. | asymmetric competition in larval amphibians can influence population dynamics and community structure. this density-dependent regulatory mechanism may be of particular importance for rare or endangered species such as the northern crawfish frog, rana areolata circulosa. interspecific competition of r. areolata with two congenerics, r. blairi and r. sphenocephala, was examined in artificial ponds. analysis of covariance (differential mortality covariate) indicated that interspecific competition i ... | 1998 | 28308529 |
