This may reflect a history of stronger selection by pathogens and predators that accumulate in ponds as the breeding season progresses. To our knowledge, these are the first examples of induced hatching of amphibians in response to aquatic pathogens.Touchon...
The status of common bird populations is both an accepted indicator of wider ecosystem health1and a direct influence on human wellbeing via interactions with nature2. Conservation attention most often focuses on rare and range-restricted species. Nevertheless, there are examples of rapid decline in ...
Give two examples of animals with an open circulatory system. Explain how the structure and function are linked together for the following organs of the digestive system: 1) Mouth 2) Oesophagus 3) Stomach 4) Small intestine 5) Large intestine 6) Rectum 7) Anuss ...
"We chose these two because they are the most recent examples of rapid climate warming and have been widely studied so we have more information about them," said Paula Mateo, a geologist at Caltech, who will be presenting the study on Wednesday. Both ancient global warming events were, like...
What is the basic difference between the heart of reptiles and amphibians? Provide three examples of each of the four types of tissue, found in animal bodies, and how they function. Describe the different parts of the femur. What are the unique features of cardiac contractile cells that ...
There are a number of examples where this is the case. For example, 'quasicrystals'—metallic alloys that are crystalline but have no repeating units and are used to coat some non-stick pans—have been shown to have 'hidden dimensions:' their structures can be understood as projections from ...
Unfortunately, most examples of applying formal adaptive management in natural resource management have failed because of three main problems: (1) lack of funding for monitoring, (2) failure of decision makers to embrace the AM concept and (3) lack of leadership to sustain a complex process (pa...
Examples in this field of research are studies of the sensitivity of inner ears, statocyst systems and other mechanoreceptors to substrata vibration occurring in mammals (e.g. moles and small rodents), reptiles, amphibians (toads), arthropods and other invertebrates. In addition, in hearing ...

Following decades of harvest, agricultural cultivation, overgrazing by livestock, exclusion of frequent surface fires, and stand conversions to plantations of other tree species, scientists and managers have few contemporary examples of functional longleaf pine upon which to develop restoration strategies. ...
