Gene Silencing Technology Alters Sex Of Prawns
2014-07-01 03:28:58

Society for Experimental Biology Israeli scientists have developed a novel method for generating single-sex populations of prawns. This could be used to boost the productivity of aquaculture farms and even as a biocontrol measure against invasive species and pests. Male sexual differentiation in crustaceans is regulated by the androgenic gland. It is thought that this overrides a default program of female differentiation, allowing male features to develop. This comes from the...

Infectious Diseases Play Part Of Declining Chesapeake Blue Crab Population
2014-06-17 03:49:40

National Science Foundation It's almost summer. Seafood restaurants from coast-to-coast are serving platter after platter of steaming crabs, ready for hammering and picking. The supply seems endless, but is it? Not if we're talking about blue crabs from Chesapeake Bay. The bay's iconic blue crab population has dropped to levels not seen since before restrictions were placed on the fishery more than five years ago. What's to blame? A long and, by Mid-Atlantic standards, brutal...

New Fossil Evidence Shows Reproductive Changes During Transition From Dinosaurs To Birds
2014-05-30 13:14:34

Brett Smith for redOrbit.com - Your Universe Online Over the course of millions of years, some dinosaurs evolved into the modern birds we see today – and that transition included the shift to a single-ovary reproductive system, according to a new report in the National Science Review journal. The study authors said this change was probably advantageous to flying animals that evolved toward lighter and lighter weights. "The most widely accepted hypothesis for the presence of a...

Leaf Chewing Links Insect Diversity In Tropical Forests
2014-05-05 03:53:42

By A'ndrea Elyse Messer, Penn State Observations of insects and their feeding marks on leaves in modern forests confirm indications from fossil leaf deposits that the diversity of chewing damage relates directly to diversity of the insect population that created it, according to an international team of researchers. "The direct link between richness of leaf-chewing insects and their feeding damage across host plants in two tropical forests validates the underlying assumptions of many...

Sponges are usually considered to be the oldest living animals, having evolved before all other groups. The simplicity of their body structure and tissue organization has for many years made them candidates for the ancestral group of animals, and they have long been regarded as our best illustration of what the earliest animals would have looked like. This has been supported by genetic analyses, which suggest that sponges branched from other animals a very long time ago, deep in the...
