Leaf chewing links insect diversity in modern and ancient forests

Observations of insects and their feeding marks on leaves in modern forests confirm indications from fossil leaf deposits that the diversity of chewing damage relates directly to diversity of the insect population that created it, according to an international team of researchers. "The direct link between richness of leaf-chewing insects and their feeding damage across host plants in two tropical forests validates the underlying assumptions of many paleobiological studies that rely on damage-type richness as a means to infer changes in relative herbivore richness through ...

Salk scientists reveal circuitry of fundamental motor circuit

LA JOLLA—Scientists at the Salk Institute have discovered the developmental source for a key type of neuron that allows animals to walk, a finding that could help pave the way for new therapies for spinal cord injuries or other motor impairments related to disease. The spinal cord contains a network of neurons that are able to operate largely in an autonomous manner, thus allowing animals to carry out simple rhythmic walking movements with minimal attention—giving us the ability, for example, to walk while talking on the phone. These circuits control properties such as ...

Which came first, bi- or tricellular pollen? New research updates a classic debate

With the bursting of spring, pollen is in the air. Most of the pollen that is likely tickling your nose and making your eyes water is being dispersed in a sexually immature state consisting of only two cells (a body cell and a reproductive cell) and is not yet fertile. While the majority of angiosperm species disperse their pollen in this early, bicellular, stage of sexual maturity, about 30% of flowering plants disperse their pollen in a more mature fertile stage, consisting of three cells (a body and two sperm cells). And then there are plants that do both. So which ...
