Tree of Life Web Project Species 2000 AquaMaps Search Page BIOTIC The Biological Traits Information Catalogue (BIOTIC) aims to provide scientists working within the field of benthic community ecology with an additional tool for their data analyses. Biological traits information of benthic species contained in the BIOTIC database can be downloaded and linked to benthic survey data. This may allow benthic data to be analysed not only on a taxonomic level but also on a functional level. The BIOTIC database contains information on over 40 biological trait categories on selected benthic species, together with additional supporting information, including a bibliography of literature from which the information was obtained. The emphasis is on benthic invertebrates and plants. Users can browse the species list or search for information by specific categories of biological trait. We would like BIOTIC to be viewed as a first source of information on which scientists can draw when conducting a traits analysis on their specific benthic datasets. MarLIN, 2006.
The Taxonomicon Catalogue of Life - 2011 Annual Checklist :: Search all names IPNI - International Plant Names Index Threats to Biodiversity | GEOG 030: Geographic Perspectives on Sustainability and Human-Environment Systems, 2011 Printer-friendly version “Extinction is the most irreversible and tragic of all environmental calamities. With each plant and animal species that disappears, a precious part of creation is callously erased.” -Michael Soulé, noted American conservation biologist It is estimated that the current rate of species extinction is between 1,000 and 100,000 times more rapid than the average rate during the last several billion years. The growth of human populations, consumption levels, and mobility is the root of most of the serious threats to biodiversity today. While learning about the negative impacts of humans on biodiversity, please keep a few things in mind. There are many threats to biodiversity today. Habitat Loss: This occurs when a particular area is converted from usable to unusable habitat. Deforestation in the Amazon River Basin often occurs in a “fish-bone” pattern, meaning that larger areas of habitat are fragmented and degraded than are actually cleared for agricultural use.
Wikispecies, free species directory CoL DB Using The Catalogue of Life is a joint product of Species 2000 and ITIS. There are currently two editions, the Annual and Dynamic Checklists. The differences between these editions are outlined on the 'About the Catalogue of Life ' page. There are many ways to access the Catalogue of Life depending on your requirements but please note that not all methods can be used to access both the Annual and Dynamic Checklists: Standard users Web interfaces - The primary search interface to the Catalogue of Life is available on the Catalogue of Life website. Advanced users When using the Catalogue of Life in your own system it is important to abide by the terms and conditions of use and notify the Species 2000 Secretariat. Web services - There are two web services available to automatically query the two editions of the Catalogue of Life and then use the data within your own system.
Plant List In Dead Water - Climate Change, Pollution, Over-harvest, and Invasive Species in the World's Fishing Grounds Sites with dead zones (oxygen depletion on the sea bottom) Dead zones (hypoxic i.e. oxygen deficient water) in the coastal zones are increasing, typically surrounding major industrial and agricultural centers. This is commonly occuring due to nutrient pollution, in the form of nitrogen and phosphorous leading to algal blooms and eutrophication 01 Feb 2008 - by Hugo Ahlenius, UNEP/GRID-Arendal Deep waters within and beyond areas of national jurisdiction in East Africa The figure demonstrates that the overwhelming majority of marine areas under national jurisdiction in East Africa are deeper than 200 metres (dark blue). 01 Feb 2008 - by UNEP-WCMC and UNEP/GRID-Arendal Estimated contributions to sea-level rise (1993-2003) The two main reasons for sea-level rise are thermal expansion of ocean waters as they warm, and increase in the ocean mass, principally from land-based sources of ice (glaciers and ice caps, and the ice sheets of Greenland and Antarctica).
