Passively stuck: death does not affect gecko adhesion strength.

abstract：:A challenge in animal ecology is to link animal movement to demography. In general, reproducing and non-reproducing animals may show different movement patterns. Dramatic changes in reproductive status, such as the loss of an offspring during the course of migration, might also affect movement. Studies linking movemen...

Here, we offer the first evidence that plastic loss of ...
