See-Through Frog Embryos Know When Dad's Not Watching

By Charles Q. Choi, Live Science Contributor | April 29, 2014 07:01pm ET

With their hearts, guts and other internal organs visible through translucent skin, glass frogs look vulnerable.

Now, scientists have found that the embryos of these nocturnal frogs do not like staying defenseless, so they hatch more quickly when their fathers desert them.

The early stages of life are usually the most vulnerable, and parents across many animal species protect their embryos as they develop. Birds typically brood their own eggs, resting on top of them for incubation, while humans and similar mammals protect embryos within themselves during pregnancy. There are exceptions to such rules — for instance, cuckoos get other birds to brood their eggs.

Declines in large wildlife lead to increases in disease risk

Summary:
In the Middle Ages, fleas carried by rats were responsible for spreading the Black Plague. Today in East Africa, they remain important vectors of plague and many other diseases, including Bartonellosis, a potentially dangerous human pathogen. The researchers concluded that the "spike in disease risk results from explosions in the number of rodents that benefit from the removal of the larger animals."


One million acres of rainforest to be restored

One million hectares of rainforest and other ecosystems in Sumatra and Kalimantan, are to be restored and supported by Asia Pulp and Paper Group (APP) the organisation has announced; an area equivalent to the total acreage of pulp plantations APP currently manages.

The decision comes a year after APP’s implemented its Forest Conservation Policy (FCP), which saw an immediate and permanent cessation of natural forest clearance across its supply chain.

The initiative will require collaboration with other land managers, communities, government agencies and including Greenpeace, NGO members of APP’s Solutions Working Group and WWF who greeted the news cautiously.

“WWF and other NGOs have identified the lack of attention to APP’s deforestation legacy as a major shortcoming in the original Forest Conservation Policy,” said Rod Taylor, Director of WWF’s Global Forest Programme. “We are encouraged by this announcement and look forward to working with APP and other stakeholders to figure out the details of where and how forests will be restored and conserved under this initiative.”

FOR IMMEDIATE RELEASE

Morwenna Griffiths, speaking for the RSPB in the South West said, “To mark the RSPB’s 125th anniversary, the world famous Moorcroft studio have launched a limited edition collection inspired by the wildlife that we strive to protect.

“Designed by Moorcroft’s Kerry Goodwin, the collection contains six intricately beautiful pieces, which depict species from the charity’s All Nature Conservation Concern list. Each carefully crafted piece is stamped on the base with the words ‘made for the RSPB’ – so these really are special works of art. The animals depicted include bittern, little egret, brown hare, harvest mouse, lynx and water vole.

“We’re thrilled that Moorcroft will be donating a percentage of the profits made from sales to the RSPB – this is such a powerful gesture form Moorcroft and it gives customers that added satisfaction that not only are they investing in a very unique piece of ceramic ware, but they are also helping the RSPB to give nature a home.

“Like the RSPB, Moorcroft has over 100-years of longevity – a testament to the impeccable quality, creativity and prestige of this historical ceramics company.  Designer Kerry Goodwin has a 14 year career with Moorcroft and her designs often reflect her vibrant and warm character.

“This unique RSPB collection will be launched at Goviers of Sidmouth, Devon on Friday 25 April, 6.00-7.30pm. As well as having the opportunity to purchase items from this exclusive RSPB collection, visitors will be able to enjoy an introduction from Steven Henry of the RSPB and a complimentary drink with canapés”.

Alan Morgenroth , Manager of Goviers says : “Goviers are thrilled to be part of this exciting partnership between the RSPB and Moorcroft, the most famous name in British Art Pottery. We have come together to promote the RSPB’s campaign to protect and conserve all British wildlife.”

World’s biggest wildlife survey reports a chorus of frogs hopping around in our gardens

Almost half of people in the south west see frogs in their gardens regularly, according to the second round of results from the world’s biggest wildlife survey, run by the RSPB.

This year, for the first-time in the 36 year history of the survey, Big Garden Birdwatch participants were also asked to tell the RSPB about some of the other wildlife that visits their gardens throughout the year, including common frogs, grey squirrels, badgers and hedgehogs. This follows the release of the bird results by the charity at the end of last month.

Almost half a million people took part in the Big Garden Birdwatch and most of them supplied extra information on the other garden wildlife they see. The RSPB hopes to use it to build an overall picture of how important our gardens are for all types of wildlife and tailor its advice so people can help their wild visitors find a home, feed and breed successfully.

The RSPB’s partners, including Amphibian & Reptile Conservation Trust (ARC), People’s Trust for Endangered Species (PTES), and The Mammal Society, have been highly enthusiastic about including these data in their national datasets.

According to the results, grey squirrels came out on top overall, with two thirds of people seeing them in their West Country gardens at least once a month.  Hedgehogs were only seen regularly in a quarter of gardens and their populations have seriously declined by around 30% since the millennium. The West Country was also a garden hotspot for badgers, with over a quarter of respondents recording them regularly.
When not hibernating, the common frog takes the lead as the most abundant garden amphibian, according to the results. In the West Country eight out of ten people had seen frogs in their garden at least once, and half of people had seen them monthly.

When it comes to toads, a third of people in the south west see them monthly. The warty amphibians, which have declined especially in central and southern England, are more likely to visit gardens in rural areas, with 41% of householders in these areas seeing them on a monthly basis.
Last year, 25 wildlife organisations, including the RSPB, released the groundbreaking State of Nature report revealing 60 per cent of the wildlife species studied have declined over recent decades.

Many garden favourites were among the creatures shown to be in serious trouble including starlings and hedgehogs, as well as some butterflies and ladybirds. All are in danger of further declines unless more is done to provide better habitats. 

Daniel Hayhow, RSPB conservation scientist, commented: “This massive survey shows how important our gardens are for the amazing variety of wildlife living there. 

“The State of Nature report showed that we need more information across many species groups, so widening the Big Garden Birdwatch’s scope to include other animals made perfect sense.

“This is the start of something big and something very, very important. In a few years’ time we’ll be able to compare how the distribution of garden wildlife may have changed. Hopefully, the fact that more people are helping to give nature a home in their gardens and outside spaces will mean we see improvements rather than declines.”

Dr John Wilkinson, ARC Science Programme Manager, said: “It’s great to know that frogs and toads are still widespread in UK gardens, which are a crucial habitat for both of them, but worrying that toads are relatively so much less common than frogs, especially in England. Future results from Big Garden Birdwatch will be critical in helping to understand all the factors affecting all our wildlife, including amphibians.”

David Wembridge, mammal surveys coordinator for the People’s Trust for Endangered Species, said: “Gardens can be ideal habitats for mammals but from the Big Garden Birdwatch and People’s Trust for Endangered Species’ (PTES) mammal surveys, we know that only a minority of gardens are regularly used by hedgehogs – one species we’re particularly concerned about. With numbers falling in the wider countryside, doing more to encourage hedgehogs into the green spaces around our homes and places of work could make a big difference.”

Marina Pacheco, the Mammal Society's Chief Executive, said: "Those taking part in this year's Big Garden Birdwatch have captured one of the largest snapshots ever recorded for some of our most endearing and threatened mammals. It's fantastic to know that gardens can be a vital refuge for rapidly-declining species like the red squirrel and hedgehog. As well as taking part in an enjoyable survey, participants have greatly increased our understanding of the distribution and relative abundance of UK mammals."

Giving Nature a Home is the RSPB’s latest campaign, aimed at tackling the housing crisis facing the UK’s threatened wildlife. The charity is asking people to provide a place for wildlife in their own gardens and outside spaces – whether it by planting pollen-rich plants to attract bees and butterflies, putting up a nestbox for a house sparrow, or creating a pond that will support a number of different species.

The RSPB hopes to inspire people across the UK to create a million new homes for nature.

2.       This year Big Garden Birdwatch participants were asked to record the wildlife they see in their gardens throughout the year from a list of eight non-bird species (badger, hedgehog, grey squirrel, red squirrel, muntjac deer, roe deer, frog, toad). The survey asked: You may not see these creatures in your hour watching (especially frogs, toads and hedgehogs, which are hibernating right now), but we’d like to know if any of them visit your garden or park, and if so, roughly how often (daily, weekly, monthly, less than monthly, never, don’t know). The survey also recorded whether their gardens were urban, suburban or rural.

3.       The State of Nature report: For the first time ever, the UK’s wildlife organisations have joined forces to undertake a health check of nature in the UK and its Overseas Territories. Working side-by-side, 25 wildlife organisations have compiled stock take of all our native wildlife. The report reveals that 60 per cent of the species studied have declined over recent decades. More than one in ten of all the species assessed are under threat of disappearing from our shores altogether. However, the report illustrates that targeted conservation has produced inspiring success stories and, with sufficient determination, resources and public support, we can turn the fortunes of our wildlife around.
