Amphibians are particularly vulnerable to changes in the landscape because they depend on connectivity between terrestrial and aquatic habitats due to the biphasic life cycle present in most species, resulting in the need to use water bodies for breeding and terrestrial habitats for the rest of their...
More likely, many native parasites are taken up by cane toads but fail to survive because of the host’s ability to mount an effective immune defence. Experimental studies show that native frogs can deal effectively with the toad’s lungworm species in this way (Pizzatto et al., 2010), ...
Explain how fertilization happens in fish and frogs? Why is a plant's life cycle called an alternation of generations? Why are seed plants the most successful terrestrial plants? Describe the methods of reproduction used by protists. How are some unicellular organisms able to grow so big? How...
Do you think DDT has the potential to cause more long-term harm to an estuary ecosystem or a terrestrial (on land) ecosystem?DDT, a Popular Pesticide:In the 1940s and 50s, DDT was used to help eliminate malaria carrying mosquitoes from North...
(Nakanishi et al., unpublished data). However, aerial insecticide application may have lethal effects across Odonata taxa. If larvae were present in conventional paddy fields during aerial application, it is unlikely that they would survive once water levels are reduced during midseason drainage (...
