Photo by Mark Elderkin Additional Information Red Knot Calidris canutus rufa subspecies - Endangered This medium sized shorebird subspecies breeds in arctic Canada and migrates thousands of kilometres between the breeding grounds and wintering areas in south America.
Now, this formerly common and tall tree is much reduced in number and in size. In Nova Scotia,the number and the sites where chimney swifts are found has also declined.
The cause of the declines is not clear but likely involves changes in insect populations due to habitat changes and pesticide use. Additionally, it includes communities of plants and animals that occur together. Threats to the species include; human alteration and loss of lakeshore habitats, water pollution, destruction of populations and habitat by ATV's and other recreational activities.
There is more biodiversity within tropical ecosystems than temperate or boreal ecosystems.
Frances Marriott What can be done. Northern Myotis are endangered by a disease known as White-nose-Syndrome caused by the fungus, Geomyces destructans.

The plant's decline caused other repercussions in the marine ecosystem as well, including large reductions in migratory waterfowl populations, loss of commercial scallop fisheries, and alterations of near-shore soft sediment habitats.
Threats to wood turtles in Nova Scotia include alteration and destruction of river and stream habitats and translocations of turtles by people. The species was thought to have been extirpated from the mainland and several re-introductions have been attempted.
Sometimes this can lead to real savings. Threats to the species include shoreline alteration, human and vehicle disturbance and eutrophication nutrient enrichment.
The decline is not well understood but involves a complex of threats including: The arrival of the non-native Seven spotted lady beetle corresponded with a rapid decline in abundance and geographic range of the Transverse lady beetle, and may have forced the Transverse lady beetle to retreat to more specific habitat types.
The eastern sub-species, which occurs here, has declined. Threats include alteration of shoreline for development, sedimentation, agricultural practices and changes in quality and quantity of water. And must remain for all of the generations that come after us.
Although still abundant in western Canada, it remains uncertain whether the species is still present in the parts of eastern Canada, including Nova Scotia. By using an ecoregion map, we can gain a lot of clues into the ecology of different places in the United States and the world.

Biodiversity refers to the total variety of life on Earth, or the total variety of life in a given area. The biodiversity of New York includes all the different species of animals, plants, fungi, and even microorganisms and bacteria living in the state. No one knows the total number of species in.
Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other tsfutbol.com study of the spatial distribution of organisms, species and ecosystems, is.
The species we study are indicators of ecosystem health. Your contribution will help fill gaps in understanding and help to conserve life overlooked. With help from you we can provide scientific information to guide environmental policy change and empower local communities around the world to preserve and protect life.
Species extinction provides a clear but narrow window on the destruction of biodiversity – it is the disappearance of the last member of a group that is by definition rare.
Wildlife traditionally refers to undomesticated animal species, but has come to include all plants, fungi, and other organisms that grow or live wild in an area without being introduced by humans. .
Species diversity is a measure of the diversity within an ecological community that incorporates both species richness (the number of species in a community) and the evenness of species. For example, the Western Ghats have a greater amphibian species diversity than the Eastern Ghats.Wildlife biodiversity and species
