Leaf litter ants are often used to measure the overall ecological health of an area because of the large number of species present and because the health of the leaf litter is a good indication of the overall health of the forest.
It is commonly assumed that repeated logging of rainforests has catastrophic effects on biodiversity. However, studies by Leeds ecologists in northern Borneo, where timber harvests are among the highest globally, have shown that in fact over 80% of ant species found in pristine, unlogged forest were also found in forest that had been logged twice.The findings have implications for forest conservation as areas of forest where intensive logging has been carried out are typically thought to have little conservation value and are often allowed to be cleared entirely to make way for cash crops such as oil palm.
"These repeatedly logged areas can look awful, with big gaps in the tree canopy which are then invaded by grasses, leading to arguments that such areas are too badly degraded for conservation."
Dr Hamer added: "The logging clearly does have an effect on ant populations but it's not nearly as disastrous as might be expected. These areas are able to support much more diverse communities than oil palm plantations but large areas are still being converted. Preventing this needs to be a priority for policy-makers and conservationists in the region."
The study is part of the Royal Society's Southeast Asia Rainforest Research Programme and is published in a special edition of the Philosophical Transactions of the Royal Society. It was supported by a grant from the Leverhulme Trust.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
