Picking up on the smell of evolution
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Pitcher plants 'switch off' traps to capture more ants
Insect-eating pitcher plants temporarily 'switch off' their traps in order to lure more prey into danger, new research from the University of Bristol, UK, and the University of Cambridge, UK, has found.
Unexpected diversity of egg yolk proteins play a key role in ant sociality and castes
In the advanced online edition of Molecular Biology and Evolution, Claire Morandin et al. performed molecular evolutionary analyses on the egg yolk forming protein, Vitellogenin, and its many forms, amongst seven Formica ...
New study may aid rearing of stink bugs for biological control
Many people think of stink bugs as pests, especially as the brown marmorated stink bugs spreads throughout the U.S. However, certain stink bugs are beneficial, such as Podisus nigrispinus (Dallas), a pred ...
The overlooked effects of global change
Although the Earth is in the midst of one of the largest and most rapid ever reductions in biological diversity, we may be overlooking some of the most important aspects. That's the conclusion of a new path-finding ...
Researcher explores relationship between landscape simplification and insecticide use
A new UCSB study that analyzed U.S. Department of Agriculture (USDA) Census of Agriculture data spanning two decades (1987-2007) shows that the statistical magnitude, existence, and direction of the relationship between landscape ...
Proper developmental patterning in worms determined in part by effective range at which signaling molecule can act
During development, vertebrate embryos rely on a process called segmentation to establish fundamental body patterning. This entails the formation of orderly bands of cells, which can subsequently contribute ...
Digitized collection data to give scientists new tools for research
From bumblebees to blister beetles, the world-class University of Kansas entomology collection numbers 5 million insects pinned in drawers, each one with a tiny printed or handwritten label.
Your small living creature shoots may benefit big science
Modern digital macro photographic equipment allows everybody to shoot marvellous pictures of very small-sized living organisms, including insects. Easy access to the internet facilitates allows the daily ...
Sanction mechanism identified between ants and host plants
In nature, many forms of plant-animal mutualism exist in which each partner benefits from the presence of the other. Although mutualistic interactions offer advantages for both partners, they are nonetheless a source of conflict.
Ants use 'photo library' to find home
(Phys.org) —Ants keep a collection of 'snapshots' taken close to the nest so they can find their way home from unfamiliar locations.
Size matters for creatures of cold polar waters
Scientists at the Universities of Liverpool, Plymouth, and Radboud, Netherlands, have challenged the view that giant animals are found in polar seas because of a superabundance of oxygen in cold water.
Does your salad know what time it is? Managing vegetables' 'internal clocks' postharvest could have health benefits
Does your salad know what time it is? It may be healthier for you if it does, according to new research from Rice University and the University of California at Davis.
Research aims to fix long-held, inaccurate insect model
(Phys.org) —In humans, a polymer called melanin determines skin, eye and hair color—the darker the skin, the more melanin in a person's body. For insects, melanin is a major aspect of their immune defense ...
