Living planet report 2022

Wildlife populations monitored across the globe have declined by a massive 69 per cent between 1970 and 2018, according to this WWF's Living Planet Report (LPR) 2022. Monitored wildlife populations - mammals, birds, amphibians, reptiles and fish - have seen a devastating 69% drop on average since 1970, according to …

Life on the edge: How forest fragmentation is impacting on amphibian and reptile species

Experts call for new conservation guidelines after research shows 90% of tropical amphibian and reptile species are affected by the 'edge effect' and forest islands less than 500m in diameter are putting many at risk. Breaking up the rainforest into small 'forest islands' means more species are being forced to …

Loss of habitats and local species extinctions

Unfortunately, loss of plant and animal habitat leads to local species extinctions and a loss of diversity from ecosystems. Fortunately, not all of the extinctions occur at once. Conservation actions may still be able to save threatened species, according to William Newmark, a vertebrate zoologist at the Natural History Museum …

New research gleans climate change insight from lizard genome

Using genomic data from three lizard species, researchers gleaned insights not available before on the impact of climate change on the distribution of animal populations in South American forests. The findings improve ways of modeling the distribution of biodiversity in the past and future. Using genomic data from three lizard …

New lizard found in Dominican Republic is already at risk

The new lizard is a Greater Antillean anole named Anolis landestoyi after Miguel Landestoy, the naturalist who first spotted and photographed the species. Scientists previously believed there were no other species like the Cuban anoles from the Chamaeleolis group living on other Greater Antillean islands — that is, until Anolis …

Central bearded dragons change sex when the heat is on, study shows

Whether the Australian central bearded dragon grows up to be a male or a female depends not only on its genetics but also on the temperature of the nest in which it is incubated. What’s more, the females with male sex genes grow up to display many male behaviours – …

Rare wildlife discovered in biggest nature survey along Britain's coast

The biggest survey to date of nature along Britain’s coastline has uncovered a host of “wildlife firsts”. More than 3,400 species were recorded at 25 National Trust locations along the coastline of England, Wales and Northern Ireland in the charity’s largest ever wildlife survey. A handful have either been seen …

China Exclusive: Chinese scientists record new species in Tibet

The discovery of a new Himalayan forest frog clade in Tibet has been confirmed. It will join 12 other Chinese amphibian families. After five years of field research, scientists from Kunming Institute of Zoology under the Chinese Academy of Sciences confirmed the discovery of the rare frog that can breed …

Extremely Rare Fishing Snakes Discovered

Deep in the remote tropical forests of the northern Andes, scientists have discovered three new species of extremely rare snake. The discovery comes mere weeks after a separate team announced the discovery of a closely related snake in southwestern Ecuador. Taken together, the four newfound reptiles double the number of …

A star attraction: The illegal trade in Indian Star Tortoises

We report on illegal international trade in Indian Star Tortoises (Geochelone elegans), with a particular focus on India and Thailand.Within India, this species has received protection as a Schedule IV list species of the Wildlife (Protection) Act 1972 for over 40 years. This study documents the illegal trade of 55,000 …

Climate Change and Lizards: Reproduction Strategy May Need to Change, Researchers Say

In an attempt to adjust to increasing climate temperatures, common lizards may start breeding more frequently but also start dying off at a younger age. To better understand retilian response to climate change, an international team of researchers closely examined how a warmer climate of just two-degrees celsius would affect …

Live fast, die young: Experimental evidence of population extinction risk due to climate change

Evidence has accumulated in recent decades on the drastic impact of climate change on biodiversity. Warming temperatures have induced changes in species physiology, phenology, and have decreased body size. Such modifications can impact population dynamics and could lead to changes in life cycle and demography. More specifically, conceptual frameworks predict …

Marine life 'halves in 45 years': Overfishing, climate change and pollution blamed for 'potentially catastrophic' decline

THE number of fish, turtles and other wildlife in the world’s oceans has halved in decades, conservationists warn. Overfishing, pollution and changing climate are blamed for the ‘potentially catastrophic’ decline in marine life. From the temperate UK waters to tropical coral reefs, the planet’s seas are emptying fast, the World …

Geographic risk assessment reveals spatial variation in invasion potential of exotic reptiles in an invasive species hotspot

Invasive species are among the primary threats to biodiversity and risk assessment is one problem-solving approach that can prioritize and guide efforts to reduce the negative consequences of invasion. We used a nichemodeling framework to conduct a geographic risk assessment of exotic reptiles in the state of Florida, USA, a …

Infectious Diseases: Wildlife Disease Reporting System Launched

Scientists studying diseases threatening amphibian, reptile and fish populations now can report findings on a new online portal. This new wildlife disease reporting system is called the Global Ranavirus Reporting System (GRRS) and was developed by researchers from the University of Tennessee Institute of Agriculture (UTIA). Researchers from Purdue University …

Climate Change: Lizard Embryos Die When Subjected To Lethal Temperatures

Researchers have made a disturbing discovery about the impact of climate change on North American lizards. Due to high temperatures of 110 degrees Fahrenheit, within minutes, lizard embryos die due to immobility and their inability to seek proper shade. When their surrounding soil becomes too hot, their dwelling simply becomes …

Bees naturally vaccinate their babies: study

When it comes to vaccinating their babies, bees don't have a choice - they naturally immunise their offspring against specific diseases found in their environments, scientists say. Researchers from Arizona State University, University of Helsinki, University of Jyvaskyla and Norwegian University of Life Sciences studied a bee blood protein called …

Climate Change: Male Dragon Lizards Turn into Females with Higher Temperatures

Climate change may be turning male lizards into females. Scientists have examined Australia's bearded dragon lizards and have found that temperature plays a key role in switching a lizard's sex rapidly from one to another. "We had previously been able to demonstrate in the lab that when exposed to extreme …

Lizard sex change: Bearded dragons susceptible to climate-induced sex reversal

Wild Australian bearded dragons are susceptible to climate-induced sex change when in the egg, a study has found. Domesticated lizards have been proven to be prone to climate-induced sex reversal before but the report, published in Nature, documents the swap happening in the wild for the first time, which is …

Sex reversal triggers the rapid transition from genetic to temperature-dependent sex

Sex determination in animals is amazingly plastic. Vertebrates display contrasting strategies ranging from complete genetic control of sex (genotypic sex determination) to environmentally determined sex (for example, temperature-dependent sex determination). Phylogenetic analyses suggest frequent evolutionary transitions between genotypic and temperature-dependent sex determination in environmentally sensitive lineages, including reptiles. These transitions …

Persistence and dispersal in a Southern Hemisphere glaciated landscape: the phylogeography of the spotted snow skink (Niveoscincus ocellatus) in Tasmania

The aim of this research was to identify the effects of Pleistocene climate change on the distribution of fauna in Tasmania, and contrast this with biotic responses in other temperate regions in the Northern and Southern Hemisphere that experienced glacial activity during this epoch. This was achieved by examining the …
