  • Listing a Species As a Threatened Or Endangered Species Section 4 of the Endangered Species Act
    U.S. Fish & Wildlife Service Listing a Species as a Threatened or Endangered Species Section 4 of the Endangered Species Act The Endangered Species Act of 1973, as amended, is one of the most far- reaching wildlife conservation laws ever enacted by any nation. Congress, on behalf of the American people, passed the ESA to prevent extinctions facing many species of fish, wildlife and plants. The purpose of the ESA is to conserve endangered and threatened species and the ecosystems on which they depend as key components of America’s heritage. To implement the ESA, the U.S. Fish and Wildlife Service works in cooperation with the National Marine Fisheries Service (NMFS), other Federal, State, and local USFWS Susanne Miller, agencies, Tribes, non-governmental Listed in 2008 as threatened because of the decline in sea ice habitat, the polar bear may organizations, and private citizens. spend time on land during fall months, waiting for ice to return.

  • How Do the Extinctions of Other Creatures Affect Humans Directly?
    4/30/2020 How Do the Extinctions of Other Creatures Affect Humans Directly? How Do the Extinctions of Other Creatures Affect Humans Directly? ••• Updated March 10, 2018 By Milton Kazmeyer While extinction of animal species is part of the natural process of evolution, the expansion of the human species has led to significant increases in the extinction rate. Because humans share ecosystems with endangered species, our quality of life and our survival is linked to them. Habitat destruction, climate change, resource depletion and other factors have increased the extinction rate by a factor of 1,000, putting substantial pressure on thousands of the most vulnerable creatures on the planet. American Bison One example of how the depletion of a species affected humans is what occurred after the American bison nearly vanished in the 19th century. Originally, the bison was a common animal on the central plains, with an estimated population of 15 million, and the Native Americans of the region depended on the animal for food, leather, fur and many https://sciencing.com/extinctions-other-creatures-affect-humans-directly-20692.html 1/11 4/30/2020 How Do the Extinctions of Other Creatures Affect Humans Directly? other goods vital to a nomadic lifestyle. By 1890, however, there were only a few thousand bison left in America. Tribal hunters were able to kill more of the animals with the aid of firearms, and in some cases the United States government encouraged the widespread slaughter of bison herds. The vanishing species forced tribes dependent on the animal to move to new lands in search of food, and eventually those tribes could no longer support themselves and had to deal with the United States government for survival.

A total of 868 active nests of eight speciesof pigeonsand doves (columbids) were found in 210 0.1 ha strip-transectssampled in the three major life zones of Puerto Rico from February 1987 to June 1992. The columbids had a peak in nest density in May and June, with a decline during the July to October flocking period, and an increasefrom November to April. Predation accountedfor 8 1% of the nest lossesobserved from 1989 to 1992. Nest cover was the most important microhabitat variable accountingfor nest failure or successaccording to univariate and multivariate comparisons. The daily survival rate estimates of nests constructed on epiphytes were significantly higher than those of nests constructedon the bare branchesof trees. Rainfall of the first six months of the year during the study accounted for 67% and 71% of the variability associatedwith the nest density estimatesof the columbids during the reproductivepeak in the xerophytic forest of Gulnica and dry coastal forest of Cabo Rojo, but only 9% of the variability of the nest density estimatesof the columbids in the moist montane second-growthforest patchesof Cidra. In 1988, the abundance of fruits of key tree species(nine speciescombined) was positively correlatedwith the seasonalchanges in nest density of the columbids in the strip-transects of Cayey and Cidra.

High apparent survival of Leach’s Storm Petrels Oceanodroma leucorhoa in British Columbia. Marine Ornithology 48: 133–140. Leach’s Storm Petrels Oceanodroma leucorhoa were listed as Vulnerable by the IUCN in 2018. Population declines in the western North Atlantic are associated with low annual adult survival rates, but trends and vital rates of populations in the eastern North Pacific are poorly known. To address this knowledge gap, we estimated the annual apparent survival of breeding adults at two colonies off the coast of British Columbia (Rock Islets: 52°20ʹ40″N, 131°14ʹ10″W and Cleland Island: 49°10ʹ17″N, 126°05ʹ28″W), using capture-mark-recapture data collected between 2006 and 2010. Transient models received substantially more support than standard Cormack-Jolly-Seber models, suggesting that the initial capture and banding reduced burrow fidelity. The model-averaged annual apparent survival rates for both colonies were high (estimate for each colony = 0.975 ± 0.011), compared to rates reported for colonies in the western North Atlantic (< 0.80).

But, with the increased dependence on agriculture and industrialisation, the emphasis on biodiversity has decreased. Indeed, the biodiversity, in wild and domesticated forms, is the sources for most of humanity food, medicine, clothing and housing, much of the cultural diversity and most of the intellectual and spiritual inspiration. It is, without doubt, the very basis of life. Further that, a quarter of the earth‟s total biological diversity amounting to a million species, which might be useful to mankind in one way or other, is in serious risk of extinction over the next 2-3 decades.
