Carnivorous Sundew Plant Has Fast Snap Tentacles

[Watch the Video!] Brett Smith for redOrbit.com - Your Universe Online Many predators in the animal kingdom depend on a quick-strike ability to capture their prey, but a few species in the plant kingdom also have this impressive capability. A handful of German biologists have decided to investigate the mechanisms behind the quick strikes of one plant in particular, Drosera glanduligera, a small sundew from southern Australia. This sundew relies on its touch-sensitive tentacles to...

Carnivorous Plants Turning Vegetarian

It´s a bad sign when even carnivorous plants decide to embrace a vegetarian lifestyle. A newly published study in New Phytologist journal has revealed the common Sundew plant is becoming so full from snacking on nitrogen deposits in Swedish bogs, that they´re eating fewer bugs. These bogs are normally scant in the way of nitrogen, therefore the plants have taken to snacking on insects to supplement their diet. However, as human activities (such as industrialization and other...

Why do some insect-eating plants like sundews keep their flowers so far away from their traps? New research suggests that it isn't a clever trick to keep pollinators safe, it's about getting pollinated Sex can be complicated at the best of times, but plants have an extra difficulty. If you're a plant who relies on insects to pollinate your flowers and reproduce, you will want your flowerstalks to be long. That way your flowers are on display to insects above the crowd. But if your stalk is...

Charles Darwin described the Venus Flytrap as 'one of the most wonderful plants in the world.' It's also one of the fastest as many an unfortunate insect taking a stroll across a leaf has discovered. But what powers this speed? Dr Andrej Pavlovič of Comenius University, Slovakia, has been studying the plants with the help of some specialised equipment and a few unlucky insects. In the wild the Venus Flytrap grows in the bogs and savannahs of North and South...

Scientists have traced the origin of the Venus flytrap and another predatory plant back to a single ancestor with sticky leaves. Botanists told BBC Earth News that the plants' evolution was a result of the need to devour larger animals. This evolution caused the plants to develop new forms of weapons, including teeth and sensor hairs. There are several plants known to man that hunt prey using an array of tools. Scientists focused on the Venus flytrap and the waterwheel plant. The waterwheel...

By Yesson, C; Culham, A Abstract.- We investigate the impact of past climates on plant diversification by tracking the "footprint" of climate change on a phylogenetic tree. Diversity within the cosmopolitan carnivorous plant genus Drosera (Droseraceae) is focused within Mediterranean climate regions. We explore whether this diversity is temporally linked to Mediterranean-type climatic shifts of the mid-Miocene and whether climate preferences are conservative over phylogenetic timescales....
