Evidence of same-sex mating in nature: the story of Cryptococcus neoformans
Cryptococcus neoformans is a major cause of fungal meningitis in predominantly immunocomprised individuals.

The precise role of seminal proteins in sustaining post-mating responses in fruit flies
Successful reproduction is critical to pass genes to the next generation.

Frozen hair holds secrets of Yellowstone grizzlies
Locks of hair from more than 400 grizzly bears are stored at Montana State University, waiting to tell the tale of genetic diversity in the Yellowstone Ecosystem.

Population genetics of the Chilean frog Batrachyla leptopus (leptodactylidae)
Electrophoretic variation of proteins encoded by 14 loci was analyzed in eight (five continental and three insular) populations of the Chilean leptodactylid frog Batrachyla leptopus.

Genetics of resistance to powdery mildew (Microsphaera diffusa) in Brazilian soybean populations
Crosses between resistant and susceptible soybean cultivars were performed and the F2 populations were obtained to study the inheritance of soybean resistance to powdery mildew

The genetics and conservation of Araucaria angustifolia: I. Genetic structure and diversity of natural populations by means of non-adaptive variation in the state of Santa Catarina, Brazil
The objective of this study was to generate information relative to the allele distribution and dynamics within and among populations of Araucaria angustifolia, a naturally-occurring conifer in the south of Brazil

New discovery: Molecular variation in one gene affects the growth of natural populations
For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat.

Study links ADHD cognitive and behavioral problems to genetic and environmental interactions
A new study indicates that cognitive and behavioral problems that underlie attention deficit hyperactivity disorder, or ADHD, are due to a complex interplay of genes and the environment.

Why some aphids can't stand the heat
For pea aphids, the ability to go forth and multiply can depend on a single gene, according to new research.

Fruit Fly Aggression Studies Have Relevance to Animal, Human Populations
Even the tiny, mild-mannered fruit fly can be a little mean sometimes - especially when there's a choice bit of rotten fruit to fight over.

Urbanization favors sedentary males
Urbanization changes landscapes and local environments, which can alter the life histories and traits of the creatures living in and around these areas.

Flexible genes allow ants to change destiny
Ant larvae can be triggered by environmental stimuli to switch development depending on colony's workforce needs.

Environmental Triggers May Promote Human Genetic Variation
Scientists from Kyushu University report how environmentally damaged DNA may contribute to human genetic diversity.
