Dung beetle diversity affects Florida livestock producers

06.03.2012
Many livestock producers are unaware that herd management practices influence the effectiveness of dung beetles

Dung beetles are important to healthy cattle pasture ecosystems as they provide for nutrient recycling, removal of waste products from the soil surface and assist in the reduction of pestiferous flies.

Numerous exotic dung beetles have been accidentally or intentionally introduced to the North American continent and several of these have become established.

In "Indigenous and Exotic Dung Beetles (Coleoptera: Scarabaeidae and Geotrupidae) Collected in Florida Cattle Pastures," which will appear in the next issue of Annals of the Entomological Society of America, entomologists from the University of Florida surveyed for the presence and distribution of dung beetles on four cattle farms in north central Florida over a 3.5-yr period, and they identified 39 species from 20 genera, with a total of 62,320 beetles collected in traps.

Although most were natives, six exotic species were found as well, including four of the six most commonly collected species. Furthermore, none of these exotics were intentionally introduced to Florida.

This study provides evidence that each of these farms exhibited dynamic and unique dung beetle diversity.

According to the authors, many livestock producers request information on rearing dung beetles, but they are unaware that in most cases they alreadyhave a complementary assemblage of dung beetles on their farms, and that their herd management practices greatly influence the effectiveness of these beetles.

The study also offers a profile of dung beetle activity of much longer duration than others published in the United States, and it documents that variations between sites can be substantial. Four of the six most commonly collected beetles were introduced species, suggesting that either a niche was available for these species on cattle farms in Florida or that these species displaced the more generalist and perhaps adaptive native species.

The Annals of the Entomological Society of America (http://entsoc.org/Pubs/Periodicals/Ann) is published by the Entomological Society of America (http://www.entsoc.org), the largest organization in the world serving the professional and scientific needs of entomologists and people in related disciplines.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
