AbstractLymphedema is a condition in which the lymph hearts fail to pump fluid from the lymph sacs of anurans and other amphibians. This causes the sacs to fill with fluid and provide the frog with balloon-like swellings or over-all appearance. The condition has previously been connected with various diseases including tadpole edema virus and chytrids. I observed lymphedema in six anuran species (Acris blanchadi*, Anaxyrus fowleri*, Hyla squirrela*, Pseudacris streckeri illinoensis*, Rana sylvatica, Rana sphenocephala* [species with * are species records for lymphedema]).

Anuran Species

In anurans, acoustic signal traits are useful for understanding patterns of evolutionary processes, behavioral interactions, and providing diagnostic characters for inferring phylogenetic relationships and delimiting species (Cocroft & Ryan 1995). The advertisement call, which is the vocalization emitted to attract females or segregate conspecific males, is the most conspicuous and studied acoustic signal (Toledo et. al. 2014). However, it remains unknown for many anuran species (Köhler et al. 2017; Guerra et al. 2018).

The frequency of the middorsally striped morph of Rana sylvatica in Ontario and Manitoba varies from absence in southern Ontario to 80% on the coast of Hudson Bay, with a general value of 20–30% in the boreal forest, a rise to 50% on the forest–grassland ecotone in southern Manitoba, and a decline westward to 20% on the edge of the prairies. This morph is rare in the northeastern United States and Maritime Canada. The suggested relationship between its frequency and the "grassiness" of the background on which predators view it is reexamined, and it is suggested that a linkage with earlier transformation as demonstrated in Eurasian species may explain certain anomalies.

Larval diets of two anuran species, Pelodytes punctatus and Bufo bufo, in SW Spain

AbstractDiets of both species studied were basically composed of algae and detritus. For Pelodytes punctatus, other food types exhibited minor contributions to the diet. For Bufo bufo, phanerogams reached considerable proportions too and the frequency of animals may be considered noteworthy if related to other species in the area. Morphologically they seem to be both conditioned to bottom dwelling rather than to the use of water column.

Climate change has been associated in phenological shifts for a variety of taxa. Amphibians, specifically the order Anura (frogs and toads), are considered particularly vulnerable due to their sensitivity to anthropogenic and environmental change. Previous research has documented shifts in the timing of anuran breeding that can be attributed, in part, to climate change, with potential implications for reproduction, survival, and development. This study aims to investigate how air temperature is associated with anuran calling phenology. I will examine the temporal trends in spring and summer air temperature in a lake in northern Ontario, Canada. and quantify seasonal patterns of calling anuran species using acoustic monitoring over a four-month period. I predict that there will be interspecific variation in peak calling associated with air temperature. Additionally, I expect to find asymmetrical association between air temperature and anuran species’ calling behaviour – wherein prolonged breeding species will have a larger optimal temperature range for calling compared to explosive breeding species. The findings of this research will aid in future conservation and provide insight for management strategies of anurans in Canada in response to anticipated climate warming.
