During the anterior-posterior fate specification of insects, anterior fates arise in a nonelongating tissue (called the "blastoderm"), and posterior fates arise in an elongating tissue (called the "germband"). However, insects differ widely in the extent to which anterior-posterior fates are specified in the blastoderm versus the germband. Here we present a model in which patterning in both the...
A recent complete assessment of the conservation status of 5487 mammal species demonstrated that at least one-fifth are at risk of extinction in the wild. We retrospectively identified genuine changes in extinction risk for mammals between 1996 and 2008 to calculate changes in the International Union for Conservation of Nature (IUCN) Red List Index (RLI). Species-level trends in the conservatio...
In tropical forests, both vegetation characteristics and soil properties are important not only for controlling energy, water, gas exchanges directly but also determining the competition among species, successional dynamics, forest structure composition. However, joint effects of two factors have received limited attention in Earth system model development. Here we use a demographic model, Func...
