There's a solution to the continent's rampant fires and feral animals, says David Bowman — introduce large mammals and increase hunting pressure.

Questions have been raised about the transparency and scientific quality of regulatory processes applied in the first open field releases of genetically modified (GM) insects, and there is concern that inappropriate precedents have been set, particularly through generic risk assessments covering multiple species and technologies.

A new analysis by FAO on how climate change affects or will likely affect wild animals and their habitats. It focuses on tropical terrestrial wildlife and its habitats, but other fauna, ecosystems and geographical regions are covered as well.

New marine invasions have been recorded in increasing numbers along the world's coasts due in part to the warming of the oceans and the ability of many invasive marine species to tolerate a broader thermal range than native species. Several marine invertebrate species have invaded the U.S. southern and mid-Atlantic coast from the Caribbean and this poleward range expansion has been termed ‘Caribbean Creep’.

Overcoming boundaries is crucial for incursion of alien plant species and their successful naturalization and invasion within protected areas. Previous work showed that in Kruger National Park, South Africa, this process can be quantified and that factors determining the incursion of invasive species can be identified and predicted confidently. Here we explore the similarity between determinants of incursions identified by the general model based on a multispecies assemblage, and those identified by species-specific models.

The country would need to evolve a new policy framework and initiate purposeful action to deal effectively with forest invasive species.

The Biodiversity of Sikkim faces a number of threats due to biotic as well as abiotic factors. It is essential to identify these factors so that the remedial measures can be taken to strengthen the conservation and management of biological diversity in the state.

Plant breeders have played an essential role in improving agricultural crops, and their efforts will be critical to meet the increasing demand for cellulosic bioenergy feedstocks. However, a major concern is the potential development of novel invasive species that result from breeders' efforts to improve agronomic traits in a crop. We use reed canarygrass as a case study to evaluate the potential of plant breeding to give rise to invasive species.

Biological invasion and climate change pose challenges to biodiversity conservation in the 21st century. Invasive species modify ecosystem structure and functioning and climatic changes are likely to produce invasive species' range shifts pushing some populations into protected areas. The American Bullfrog (Lithobates catesbeianus) is one of the hundred worst invasive species in the world. Native from the southeast of USA, it has colonized more than 75% of South America where it has been reported as a highly effective predator, competitor and vector of amphibian diseases.

India stands today at the cross-roads where it is becoming abundantly clear that not paucity of funds, but deficit in governance is the most significant challenge before the society.
