The Ecology contribution to address this question is to determine possible physicochemical impacts on 1) pond water quality and biological integrity, and 2) avulsed pit pond water quality and biological integrity in the historical pit location and receiving waters. These questions will be addressed by all study partners together in a more comprehensive fashion after the interim phase of reporting.

Development and environmental issues of small cities in developing countries have largely been overlooked although these settlements are of global demographic importance and often face a “triple challenge”; that is, they have limited financial and human resources to address growing environmental problems that are related to both development (e.g., pollution) and under-development (e.g., inadequ...

One of the first things that catches the attention of a diver entering the warm waters of the coral reef is the phenomenal diversity, abundance, and beauty of fishes swimming before them. While all organisms on the coral reef are integrated into its overall ecology, fishes are certainly among the more readily observable taxons, and are an extremely important component of overall reef function. ...

successful application of a tbm in a project requires investigating both the ground conditions and the machine and backup system design features. prediction of the machine performance is very important as it has a big effect on the duration of the project and the costs. in this respect, both penetration rate and advance rate must be estimated. utilization factor, which depends on the type of op...

During the second half of the 20th century, the crisis of societal relations to nature emerged as the subject of an international scientific, political, and popular debate. Anthropogenic climate change, loss of biodiversity, resource peaks, or local air and water pollution are symptoms of this crisis. Social ecology provides an interand transdisciplinary take on sustainability research and is w...

Small mammals in habitats with strong seasonal variation in the thermal environment often exhibit physiological and behavioral adaptations for coping with thermal extremes and reducing thermoregulatory costs. Burrows are especially important for providing thermal refuge when above-ground temperatures require high regulatory costs (e.g., water or energy) or exceed the physiological tolerances of...
