Chemical pollution: a conservation threat for wild carnivores

Jaime Rodríguez Estival
Ecotoxicology

The exposure of wild carnivores to high levels of chemical pollution can be associated with less reproductive success and/or lower probabilities of survival, which may be a direct or indirect cause of population declines


Wild carnivores are species of mammals belonging to the taxonomic order Carnivora, which are fundamental drivers as regards maintaining ecosystems and preserving biodiversity. However, a number of species have undergone significant population declines over the last century...

Science and management

Linking science and environmental management is key for an adequate decision-making process in favour of nature conservation


Having a good knowledge base in the various disciplines of Environmental Sciences is fundamental for the decision-making process on which the management of natural resources is based. Likewise, it is necessary to keep abreast of the scientific advances in conservation issues so that decision-making is as effective and efficient as possible. Paradoxically, despite the...

What is biomagnification?

Jaime Rodríguez Estival
Ecotoxicology

The biomagnification of certain chemical contaminants through food webs implies a risk for the conservation of the wildlife species affected and problems of food safety and public health


In the last article of Divulgazeral we said that chemical pollution is a serious threat to the environment whose consequences are being underestimated. We discovered that this type of pollution does not understand frontiers, and that it usually goes unnoticed, so that its effects are manifested in silence,...

For instance, if we walk alongside a river and observe...
