In the first comprehensive review of the more than 4,000 native bee species in North America and Hawaii, the Center for Biological Diversity has found that more than half the species with sufficient data to assess are declining. Nearly 1 in 4 is imperiled and at increasing risk of extinction. The new analysis, "Pollinators in Peril: A systematic status review of North American and Hawaiian native bees", revealed that more than 700 species are in trouble from a range of serious threats, including severe habitat loss and escalating pesticide use.
Habitat loss has pushed the critically endangered yellow-crested cockatoo (Cacatua Sulphurea), a native bird of Sulawesi and East Nusa Tenggara, toward the brink of extinction, as the number currently living in the wild continues to decline. The International Union for the Conservation of Nature (IUCN) has listed the bird among 20 bird species that are on the brink of extinction, said Tri Endang, head of the Forest Ecosystem Control unit at the West Nusa Tenggara Natural Resources Conservation Agency (BKSDA). “The IUCN has listed the Yellow-Crested cockatoo as critically endangered.
Since the early 1990s, pesticide usage on oil seed rape (OSR) has increased significantly in terms of the number of times treated, weight per hectare applied and number of active substances. Although Budge et al (2015) established that neonicotinoid seed coatings enabled farmers to reduce the number of insecticide sprays on OSR, this is not evident from the survey data after 2000 when neonicotinoid seed treatments were introduced.
For Numeniini, a family of birds that includes Curlews and Godwits, new research indicates that these birds are at risk. A recent study by Royal Society for the Preservation of Birds (BirdLife in the UK), British Trust for Ornithology (BTO), and the International Wader Study Group suggests they could actually be one of the most threatened families of birds on earth. The study consulted over 100 experts who assessed the threats to Numeniini throughout their migratory regions and found that seven of the thirteen species are threatened with extinction.
Where have all those chirpy little sparrows gone? Once a common sight, hopping away on the verandahs and chirping joyously from tree branches, the sight of a sparrow (Passer domesticus) has over the years become a rarity.The tentacles of development spreading with fast paced concretisation of the city have ended in choking away one of mankind’s oldest associate. As the city prepares to join the World Sparrow Day on March 20, it is left to a few individuals concerned at the fast decline in sparrow population, to bring them into focus.
A conservationist has called on the Scottish government to act to protect the much-loved puffin (Fratercula arctica) amid warnings that populations of the iconic bird are in terminal decline. Philip Lymbery, chief executive of Compassion in World Farming, points to a population crash of Scottish puffins due to overfishing in the North Sea.
This report reviews the existing scientific evidence regarding the impact of organic food on human health from an EU perspective and the potential contribution of organic management practices to the development of healthy food systems. Very few studies have directly addressed the effect of organic food on human health. They indicate that organic food may reduce the risk of allergic disease and obesity, but this evidence is not conclusive. Consumers of organic food tend to have healthier dietary patterns overall.
“I am Assam’s State bird Deo hah. My current status is threatened. Please do not kill us, nor collect our ducklings or eggs” – reads a new campaign poster of wildlife NGO Aaranyak, starkly describing the current status of the State bird, the white-winged wood duck (Asarcornis scutulata). As the rhino continues to be the focus of wildlife conservation in the State, the numbers of the white-winged wood duck are dwindling slowly and silently with little or no attention coming from the State Government.
The number of nesting wading birds in South Florida, a key measure of Everglades health, sunk to a decade-long low last year, according to a South Florida Water Management District report released this week, the latest in a 22-year tally. Just over 26,000 nesting birds were counted across the Everglades and in Lake Okeechobee last year, well below the 10-year annual average of about 42,000.
