Species conservation poised to benefit from DNA advances

A biologist at the University of York is part of an international team which has shown that advanced DNA sequencing technologies can be used to accurately measure the levels of inbreeding in wild animal populations.

Immune system study could help conserve endangered species

(Phys.org) —A study by University of Georgia ecologists has found that diversity in mammal immune system genes may have more to do with the opportunity to choose a mate than with exposure to parasites.

Environmentalists slam catfight over India's lions

Environmentalists Tuesday slammed an Indian state's attempt to halt the relocation of some of the country's endangered lions, saying it was undermining efforts to boost their dwindling numbers.

Capsella provides insight into the genomic results of selfing

About 200,000 years ago, Capsella rubella began self fertilizing and split from C. grandiflora. To study the effects of selfing on C. rubella's genome, the Department of Energy Joint Genome Institute sequenced and compared ...

Research shows male guppies reproduce even after death

Performing experiments in a river in Trinidad, a team of evolutionary biologists has found that male guppies continue to reproduce for at least ten months after they die, living on as stored sperm in females, who have much ...

How does inbreeding avoidance evolve in plants?

Inbreeding is generally deleterious, even in flowering plants. Since inbreeding raises the risk that bad copies of a gene will be expressed, inbred progeny suffer from reduced viability.

Brazilian team finds new porcupine species

A new species of tree-dwelling porcupine has been discovered in Brazil's Northeastern Atlantic Forest, one of the world's most threatened habitats, researchers said.
