New study explores beetle species with two forms of females
January 25, 2006A fascinating new study from the forthcoming issue of The American Naturalist attempts to explain the mysterious persistence of two forms of females in many diving beetle populations. Their findings have important implications for theories of sexual conflict, which arises when the costs and benefits of multiple matings differ for males and females.
"The male versus female arms race (involving physical structures, behaviors, chemicals, etc.) for control over mating may take place over evolutionary time, which in theory can lead to the formation of a new species," explain the authors.
"The results have implications for the understanding of how genetic diversity is maintained in populations where sexual conflict characterizes the mating system," write the authors. "It also affects our theoretical expectations of sexual conflict as a species creator."

Beetle Species Current Events and Beetle Species News RSSDogs, maybe not, but old genes can learn new tricks
A popular view among evolutionary biologists that fundamental genes do not acquire new functions was challenged this week by a new study in the Proceedings of the National Academy of Sciences.
How 'secondary' sex characters can drive the origin of species
The ostentatious, sometimes bizarre qualities that improve a creature's chances of finding a mate may also drive the reproductive separation of populations and the evolution of new species, say two Indiana University Bloomington biologists.
The flourbeetle's genome sequenced for the first time
An international research consortium with the participation of a research team led by Professor Cornelis Grimmelikhuijzen from the Department of Biology, has sequenced the genome from the red flour beetle Tribolium castaneum.
Beetle dung helps forests recover from fire
Armed with a pair of tweezers and a handful of beetle droppings, University of Alberta forestry graduate Tyler Cobb has discovered why the bug-sized dung is so important to areas ravaged by fire.
X-ray images help explain limits to insect body size
Researchers at the U.S. Department of Energy's Argonne National Laboratory have cast new light on why the giant insects that lived millions of years ago disappeared.
Do we need a paradigm change? Disputing coevolution in herbivorous insects
Coleoptera (beetles) are one of the most successful groups of organisms on Earth. Their success in evolutionary terms is recognised by their extreme adaptive diversity (occupying almost every possible ecological niche) and their longevity (fossils from the Palaeozoic, 280 million years ago).
Discovery of new cave millipedes casts light on Arizona cave ecology
A new genus of millipede was recently discovered by a Northern Arizona University doctoral student and a Bureau of Land Management researcher.
Vanishing beetle horns have surprise function
The function of horned beetles' wild protrusions has been a matter of some consternation for biologists. Digging seemed plausible; combat and mate selection, more likely. Even Charles Darwin once weighed in on the matter, suggesting - one imagines with some frustration - the horns were merely ornamental.

The Biology of Tiger Beetles and a Guide to the Species of the South Atlantic States (Special Publication Series, No. 5) by C. Barry Knisley (Author), Tom D. Schultz (Author) Tiger Beetles are one of the most-studied groups of non-pest insects and are increasingly chosen as indicator species for efforts to preserve natural habitats. This richly illustrated book provides a review of research on the natural history, systematics, behavior, physiology, ecology, and conservation of tiger beetles. The authors draw upon past and recent studies and their own extensive research experience to provide a synthesis of current knowledge on tiger beetle biology. Moreover, they apply this knowledge to a detailed description of the rich fauna of the south Atlantic coastal states (Delaware to Georgia); a region where tiger beetle populations have been little studied but heavily impacted by change. |

Habitat modelling for the conservation of the rare ground beetle species Carabus variolosus (Coleoptera, Carabidae) in the riparian zones of headwaters [An article from: Biological Conservation] by A. Matern (Author), C. Drees (Author), M. Kleinwachter (Author), T. Assmann (Author) This digital document is a journal article from Biological Conservation, published by Elsevier in 2007.

Description: Carabus variolosus is a highly endangered insect which is listed in the EC Habitats and Species Directive. Detailed knowledge of the habitat requirements of this semi-aquatic woodland carabid beetle is needed if effective conservation and management strategies are to be developed. Previous habitat models have proved to be a successful analytical and predictive tool for the conservation of species. We conducted an intensive study over a two year period on two extant C. variolosus populations in Westphalia... |

Rethinking a rare-species conservation strategy in an urban landscape: The case of the valley elderberry longhorn beetle [An article from: Biological Conservation] by T.S. Talley (Author), E. Fleishman (Author), M. Holyoak (Author), D.D Murphy (Author) This digital document is a journal article from Biological Conservation, published by Elsevier in 2007. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Reflecting the lack of critical information for most protected species, recovery plans for organisms listed as threatened or endangered under the U.S. Endangered Species Act tend to oversimplify habitat descriptions. Here we present our approach for improving the definition of habitat for rare and patchily distributed listed species. The valley elderberry longhorn beetle (Desmocerus californicus dimorphus) occurs in riparian and scrub communities in California's Central Valley. Habitat quality for the species... |
