Brazil: ‘Worst’ deforestation gang broken up
Thursday 28th august 2014
The gang had been invading public land in northern Para state, burning down forest, dividing the land into parcels and selling it, federal police said.
The Brazilian Environmental Institute estimated that the criminal group had been responsible for environmental crimes to the tune of $230 million (£138.7m).
“The suspects are considered to be the greatest destroyers of the Brazilian Amazon currently active,” the institute said.
They should be charged with invading public land, environmental crimes, forgery, criminal association and money-laundering, it added.
If convicted, the suspects face more than 50 years in prison.
Police did not say how many arrests they are expecting to carry out during the operation.

There is an overdue and urgent need to establish patterns of migratory connectivity linking breeding grounds, stopover sites, and wintering grounds of migratory birds. Such information allows more effective application of conservation efforts by applying focused actions along movement trajectories at the population level. Stable isotope methods, especially those using stable hydrogen isotope abundance in feathers (δ2Hf) combined with Bayesian assignment techniques incorporating prior information such as relative abundance of breeding birds, now provide a fast and reliable means of establishing migratory connectivity, especially for Neotropical migrants that breed in North America and molt prior to fall migration.
Here we demonstrate how opportunistic sampling of feathers of 30 species of wintering birds in Cuba, Venezuela, Guatemala, Puerto Rico, and Mexico, regions that have typically been poorly sampled for estimating migratory connectivity, can be assigned to breeding areas in North America through both advanced spatial assignment to probability surfaces and through simpler map lookup approaches. Incorporating relative abundance information from the North American Breeding Bird Survey in our Bayesian assignment models generally resulted in a reduction in potential assignment areas on breeding grounds.
However, additional tools to constrain longitude such as DNA markers or other isotopes would be desirable for establishing breeding or molt origins of species with broad longitudinal distributions. The isotope approach could act as a rapid means of establishing basic patterns of migratory connectivity across numerous species and populations.
We propose a large-scale coordinated sampling effort on the wintering grounds to establish an isotopic atlas of migratory connectivity for North American Neotropical migrants and suggest that isotopic variance be considered as a valuable metric to quantify migratory connectivity. This initiative could then act as a strategic template to guide further efforts involving stable isotopes, light-sensitive geolocators, and other technologies.

Migratory movements and wintering areas of Leach’s Storm-Petrels tracked using geolocators
Volume 85, Issue 3, pages 321–328, September 2014
Accumulating evidence suggests that Atlantic populations of Leach’s Storm-Petrels (Oceanodroma leucorhoa) are experiencing significant declines. To better understand possible causes of these declines, we used geolocators to document movements of these small (∼50-g) pelagic seabirds during migration and the non-breeding period. During 2012 and 2013, movement tracks were obtained from two birds that traveled in a clock-wise direction from two breeding colonies in eastern Canada (Bon Portage Island, Nova Scotia, and Gull Island, Newfoundland) to winter in tropical waters.
The bird from Bon Portage Island started its migration towards Cape Verde in October, arrived at its wintering area off the coast of eastern Brazil in January, and started migration back to Nova Scotia in April. The bird from Gull Island staged off Newfoundland in November and then again off Cape Verde in January before its geolocator stopped working. Movements of Leach’s Storm-Petrels in our study and those of several other procellariiforms during the non-breeding period are likely facilitated by the prevailing easterly trade winds and the Antilles and Gulf Stream currents. Although staging and wintering areas used by Leach’s Storm-Petrels in our study were characterized by low productivity, the West Africa and northeastern Brazilian waters are actively used by fisheries and discards can attract Leach’s Storm-Petrels.
Our results provide an initial step towards understanding movements of Leach’s Storm-Petrels during the non-breeding period, but further tracking is required to confirm generality of their migratory routes, staging areas, and wintering ranges.

Translated from the Dutch Mycological Society on Wednesday, August 27th, 2014:
In the dunes of Schoorl is the very rare Chamaemyces fracidus mushroom has been found. The species still lives only at six places in the Netherlands. The mushroom was in the verge of a seashell cycle track. The dunes of Schoorl have a low lime content, but thanks to the calcareous seashell path it can grow here.

Zoos stave off extinction for many reptiles and amphibians
A frog that doesn’t croak, the largest living lizard, and a tortoise that can live up to 100 years are just some of the species staving off extinction thanks to the help of zoos, according to a new report.
The British and Irish Association of Zoos and Aquariums (BIAZA), which promotes the values of good zoos and aquariums, has compiled a list of the top 10 reptiles and amphibians benefitting from the aid of its members in the UK and Ireland.
Dr Andrew Marshall from BIAZA’s Field Programmes Committee co-ordinated the compilation of the list with input from conservation experts based at BIAZA collections.
He said: “Zoos are part of a global conservation community. Last year, BIAZA published a report on the top 10 mammals most reliant on zoos, which highlighted the work being done to help safeguard their future. This year, we have focused on 10 prevailing examples of reptiles and amphibians.
“The list includes some fantastic species, many of which are facing a dramatic decline and are in a desperate situation in the wild.”
Strict criteria were used for the list. All the reptiles and amphibians proposed had to be associated with current field initiatives by zoos and/or essential conservation breeding in zoos.
Particular importance was given to initiatives which included a management role in the species’ conservation, rather than just providing funds. Priority was also given to species listed as threatened on the international IUCN Red List of threatened species.
“The top 10 list demonstrates the importance of zoos and aquariums not only for conservation breeding of safety-net populations, but also for their contribution to funding and management of conservation projects in the field,” said Dr Marshall, “including research, education and support for local communities, as well as protection of crucial wildlife habitats.”
TV presenter and naturalist, Nick Baker, who is supporting the top 10 campaign this year said: “Zoos and aquariums have a very important role in this whole thing … at the scariest level they are the Ark. They are where the insurance populations of these animals can be looked after and understood and studied.
“As much as BIAZA is very important in holding the Ark population, it is also very important in being that interface between these animals and the public.
“The problem with these animals is they are not furry, they do not have an instant appeal to the masses. As a consequence they can be forgotten.
“The reality is, when the zoos show them to the world they are reaching people and spreading that word and getting people to appreciate what these animals are about.”
BIAZA’s top 10 reptiles and amphibians most reliant on zoos are:
Axolotl – this Critically Endangered amphibian retains a tadpole-like appearance even as an adult and has the extraordinary ability to regenerate limbs, but it is vulnerable to water-quality changes and is Critically Endangered mainly due to high levels of pollution in its last remaining stronghold in Mexico.
This video is called Axolotl salamanders continue to intrigue researchers.
Golden mantella – These Critically Endangered frogs don’t croak! Instead males attract females by a series of clicking noises. This bright yellow frog is known for attempting to eat anything that can fit in their mouth, even if the taste is repulsive.
This video is called Golden mantella chorus.
Komodo dragon – there are fewer than 1,000 left in the wild, living on a small island off Indonesia. They are the largest living lizard with males growing up to 3m in length and weighing up to 90kg.
This video is called Massive Lizards : Documentary on Giant Komodo Dragons.
Lemur leaf frog – Due to massive habitat loss and the effects of chytrid fungus, this species’ range and its population has declined by over 80 per cent in recent years. An adult lemur frog is only 3cm to 4cm long, it could fit on the end of your finger.
Morelet’s leaf frog – these striking lime-green frogs with a pink or orange underbelly are rapidly disappearing as their forest habitat is destroyed. They have incredible jet-black eyes with no discernable iris, and wide webbing between their toes which allows them to parachute between trees.
This video is called Morelet’s Tree Frog.
Mountain chicken – One of the largest frogs in the world, this Critically Endangered species came by the name because it is commonly hunted for food on the islands of Dominica and Monserrat in the Caribbean. Despite its name, it lives mainly in the lowlands.
This video is called Mountain Chicken.
Orange-tailed skink – These beautiful and highly endangered skinks were discovered on Flat Island in Mauritius in 1995 where they were being preyed upon by non-native introductions such as the Indian musk shrew. The species would now be extinct if it weren’t for the help of zoos.
Ploughshare tortoise – one of the rarest land tortoises in the world and a most sought after reptile in the illegal pet trade. This Critically Endangered tortoise is endemic to Madagascar and can live up to 100 years.
This video is called Ploughshare Tortoises, Madagascar.
Round island boa – the only snake in its genus, found only on one small island off Mauritius, where it is suffereing from loss of habitat. It is one of the very few snake species that can change its colour over a 24-hour period, being darker during the day and lighter at night.
This video is called Round Island Boa.
Sand lizard – although common in other parts of the world, this is one of the UK’s rarest lizards, protected here by law, as it is in most of Europe. It is restricted to sand dunes and lowland heaths in southern England.
