| Land animals proliferate faster than aquatic counterparts Posted: 07 Aug 2015 07:07 PM PDT New analyses of vertebrate groups performed by an evolutionary biologist suggest that land animals proliferate more rapidly than their aquatic counterparts. The findings may help explain biodiversity patterns throughout the animal kingdom. |
| First genetic atlas of butterflies of the Iberian Peninsula Posted: 05 Aug 2015 04:55 AM PDT The first atlas of genetic diversity of butterflies in the Iberian Peninsula has been created by researchers who have been sequencing the mitochondrial DNA from 228 known species and main populations of butterflies throughout the peninsula since 2006. The result is a comprehensive work with some 3,500 genetic sequences of all species, which have been added to those already existing in the rest of Europe. |
| Sardines, anchovies, other fast-growing fish vulnerable to dramatic population plunges Posted: 04 Aug 2015 05:27 PM PDT A marine biologist studying the rise and fall of fish populations worldwide recently made a counterintuitive discovery: ocean species that grow quickly and reproduce frequently are more likely to experience dramatic plunges in population than larger, slower growing fish such as sharks or tuna. In nearly all of the cases, overfishing was the culprit. Combining climate variability with high levels of fishing greatly increases the risk of population collapse. |
| Can habitat protection save our disappearing bats? Posted: 04 Aug 2015 11:34 AM PDT In summertime, bats are a common feature in the night sky, swooping around backyards to gobble up mosquitoes. Bats also help with crops: they act as a natural pesticide by feeding on harmful insects. But these winged mammals are now under threat. In a new paper, researchers have shown that protecting natural habitats in systems that are highly modified by humans could help struggling bat populations. |
