Growing up in a new world: trait divergence between rural, urban, and invasive populations of an amphibian urban invader

چکیده

Cities are focal points of introduction for invasive species. Urban evolution might facilitate the success species in recipient urban habitats. Here we test this hypothesis by rearing tadpoles a successful amphibian coloniser and invader common garden environment. We compared growth rate, morphological traits, swimming performance, developmental rate guttural toad ( Sclerophrys gutturalis ) from native rural, urban, non-native By measuring these traits across ontogeny, were also able to compare divergence different origins as develop. The origin showed significantly slower (e.g., proportion reaching Gosner stage 31 or higher was lower at age 40 days) than origin. Yet, did not differ any performance trait examined, none divergent ontogenetic changes between These findings suggest that prior adaptation habitats larval likely does play an important role facilitating invasion toads into other Instead, evolutionary after colonization rate), together with decoupling phenotypic plasticity explain how succeeded colonising extra-limital

Rural and Urban Japanese Populations

Background It has been suggested that echocardiographically determined left ventricular mass (LVM) is useful in the prediction of hypertension. To examine the relation between LVM and subsequent blood pressure (BP) change, a 6to 8-year follow-up was conducted in adult Japanese men. Methods and Results LVM was determined by M-mode echocardiography using the American Society of Echocardiography f...

A COMPARATIVE STUDY OF URBAN AND RURAL TETANUS IN ADULTS

An analysis of 382 patients, aged 12 and over, admitted to the infectious disease ward of Amin Hospital in Isfahan over a 20 year period with clinically diagnosed tetanus is reported. The study comprised 297 patients, 77.7% from rural areas and 85(22.3%) from the city of Isfahan. The male- female ratio for both groups was approximately 2:1. Rural patients were younger and showed a lower cr...

Microgeographic differentiation in thermal performance curves between rural and urban populations of an aquatic insect

The rapidly increasing rate of urbanization has a major impact on the ecology and evolution of species. While increased temperatures are a key aspect of urbanization ("urban heat islands"), we have very limited knowledge whether this generates differentiation in thermal responses between rural and urban populations. In a common garden experiment, we compared the thermal performance curves (TPCs...
