Evidence of niche shift and invasion potential of Lithobates catesbeianus in the habitat of Mexican endemic frogs
Invasive alien species are one of most severe threats to biodiversity and natural resources. These biological invasions have been studied from the niche conservatism and niche shifts perspective. Niche differentiation may result from changes in fundamental niche or realized niche or both; in biological invasions, niche differences between native and non-native ranges can appear through niche ex...
متن کاملChromosome evolution in dendropsophini (Amphibia, Anura, Hylinae).
Dendropsophini is the most species-rich tribe within Hylidae with 234 described species. Although cytogenetic information is sparse, chromosome numbers and morphology have been considered as an important character system for systematic inferences in this group. Using a diversity of standard and molecular techniques, we describe the previously unknown karyotypes of the genera Xenohyla, Scarthyla...
متن کاملChromosome evolution in Cophomantini (Amphibia, Anura, Hylinae)
The hylid tribe Cophomantini is a diverse clade of Neotropical treefrogs composed of the genera Aplastodiscus, Boana, Bokermannohyla, Hyloscirtus, and Myersiohyla. The phylogenetic relationships of Cophomantini have been comprehensively reviewed in the literature, providing a suitable framework for the study of chromosome evolution. Employing different banding techniques, we studied the chromos...
متن کاملAnti-proliferative effect of hibernating American bullfrog, Lithobates catesbeianus, blood plasma on the THP-1 cells
Hibernation is a remarkable process that allows an organism to go dormant for long periods of time during the winter, when food is scarce and living conditions can be lethal. Much is unknown about the physiology behind hibernation, and most research comes from mammalian models. For example, it is known that during hibernation many of the cells in the body are impeded from going though mitosis b...
متن کاملMicroscopic Morphology and Testis Morphometry of Captivity-bred Adult Bullfrogs (Lithobates catesbeianus
The aim of this work was to study the testicular morphometry of captivity-bred adult bullfrogs. Fifteen young adult male were studied, in the rainy season and a lengthy photoperiod. The GSI was established at 0.15%. The nuclear diameter of germinative and Leydig cells, the nucleolus diameter of Sertoli cells and the area of cysts and tubules were determined and the mean number of ISPC, IISPC an...
