The Second Report on the State of the World

The continued growth of human populations and of per capita consumption have resulted in unsustainable exploitation of Earth’s biological diversity, exacerbated by climate change, ocean acidification, and other anthropogenic environmental impacts.

Species distribution models (SDMs) are increasingly used for extrapolation, or predicting suitable regions for species under new geographic or temporal scenarios. However, SDM predictions may be prone to errors if species are not at equilibrium with climatic conditions in the current range and if training samples are not representative.

A comprehensive inventory of the invasive alien flora of India's fifth largest and most populous state, Uttar Pradesh was done.

The accelerating rates of international trade, travel, and transport in the latter half of the twentieth century have led to the progressive mixing of biota from across the world and the number of species introduced to new regions continues to increase.

There has been increased funding for wildlife conservation efforts in recent years. These funds have largely been spent on "habitat improvement" activities. In the absence of a scientific evaluation of such activities, inappropriate management of landscapes has led to human-wildlife conflicts in certain areas. Moreover, funds are being used for construction of conservation structures, forest roads and planting of exotic tree species without assessing the resulting adverse ecological effects and the gradual degradation in the quality of wildlife habitat.

The genus Quercus (oak) is a large group of hardwood trees with about 600 species worldwide1. In the Himalayan region, extensive oak forests (35 species) occur between 1500 and 3300 m elevations. Of the various species of oaks, the white oak or banj (Q. leucotrichophora) forms an extensive belt along the middle elevation (1200

The feral domestic cat (Felis catus) is a predatory invasive species with documented negative effects on native wildlife. The issue of appropriate and acceptable feral cat management is a matter of contentious debate in cities and states across the United States due to concerns for wildlife conservation, cat welfare, and public health. Common management strategies include: Trap-Neuter-Release, Trap-Neuter-Release with removal of kittens for adoption and Trap-Euthanize.

Planted in the early 20th century to help control erosion, kudzu is a fast-growing invasive legume that fixes atmospheric nitrogen at a high rate. The Asian native is not just swallowing landscapes and altering ecosystems in the southeastern United States, the plant may also increase ozone pollution. Jonathan Hickman et al.
