First Look: Banked seed replantings affected by climate change
Plants that are not able to rapidly adapt to climate change may decline and disappear from their previous habitats, prompting dramatic projects such as a doomsday vault for seeds of the world. Now researchers suggest find that seeds banked only … Continue reading

Wasps selectively pass protective bacteria on to their offspring
Symbiotic microbes are essential for the survival of many animals and plants, but the factors promoting such partnerships remain poorly understood. Now researchers find that wasps can block which bacteria their offspring receive, helping them maintain exclusive partnerships with specific … Continue reading

Evidence for speciation without geographic isolation seen in “Evolution Canyon”
The birth of a new species, the event known as speciation, is usually thought to happen when one species gets split into two or more physically isolated populations that diverge over time as they accumulate differences without interbreeding. However, it … Continue reading

One of the world’s smallest frogs, the one-centimeter-long Gardiner’s Seychelle frog, lacks a middle ear with an eardrum yet it can hear. Scientists now find it can use its mouth and bones to hear, findings detailed this week in the … Continue reading
Economic cost of fisheries-induced evolution suggests using different nets
For over seventy years, fishery managers have gathered data about the Northeast Arctic Atlantic cod in order to better manage this economically important resource. As previous research has shown, fishing induces evolutionary changes, whether selecting for a particular trait or … Continue reading

The most genetically diverse animal
The humble worm known as C. elegans is famous among biology labs as an experimental workhorse. New findings in this week’s Proceedings of the National Academy of Sciences now boost its obscure relative, C. brenneri, into the limelight, by showing … Continue reading
