Dr Paramita Punwong, former PhD student at the University of York and now Lecturer in the Faculty of Environment and Resource Studies at Mahidol University, Thailand, said: «These findings are an important contribution to understanding the long - term consequences of defaunation on a land - bridge island for human and animal communities.

«By failing to adequately limit population growth, reassess the role of an economy rooted in growth, reduce greenhouse gases, incentivize renewable energy, protect habitat, restore ecosystems, curb pollution, halt defaunation, and constrain invasive alien species, humanity is not taking the urgent steps needed to safeguard our imperiled biosphere.»

And while previous extinctions have been driven by natural planetary transformations or catastrophic asteroid strikes, the current die - off can be associated to human activity, a situation that the lead author Rodolfo Dirzo, a professor of biology at Stanford, designates an era of «Anthropocene defaunation.»

They are becoming increasingly common and successful, according to the survey in Science «Reversing Defaunation: Restoring Species in a Changing World» (2014) by the zoologist Philip Seddon at the University of Otago in New Zealand and colleagues.

More than 10 000 years ago, agricultural societies accelerated these early defaunation and land clearing processes, ultimately replacing them with even more novel ecological transformations, including the culture of domesticated species, widespread soil tillage, sustained societal growth, and ever - increasing scales of material exchange, leading to globally significant transformation of the terrestrial biosphere by at least 3000 years before the present time.

«There is growing recognition that the loss of animals from ecological communities, known as defaunation, poses a threat to carbon storage in tropical forests, but much of this understanding is derived from patterns seen in South American forests alone,» said Mahesh Sankaran of the faculty of biological sciences at the University of Leeds, UK, one of the co-authors.

«[b] y failing to adequately limit population growth, reassess the role of an economy rooted in growth, reduce greenhouse gases, incentivize renewable energy, protect habitat, restore ecosystems, curb pollution, halt defaunation, and constrain invasive alien species, humanity is not taking the urgent steps needed to safeguard our imperilled biosphere.»

In the jargon it's an «Anthropocene defaunation,» or sixth mass extinction, and one caused by humans.

«Where human density is high, you get high rates of defaunation, high incidence of rodents, and thus high levels of pathogens, which increases the risks of disease transmission,» said Dirzo, who is also a senior fellow at the Stanford Woods Institute for the Environment.

«Ironically, we have long considered that defaunation is a cryptic phenomenon, but I think we will end up with a situation that is non-cryptic because of the increasingly obvious consequences to the planet and to human wellbeing.»
