Sentence examples for migration in bats from inspiring English sources

This may represent two different functions for short- and long-distance migration in bats.

Our study is the first to test hypotheses on the evolutionary history of migration in bats using a phylogenetic framework.

In this study, we present a first analysis of the evolutionary history of migration in bats using a phylogenetic framework.

We used continuous-time Markovian models of trait evolution to model four hypotheses for the evolution of migration in bats.

In this context, the evolution and even the loss of migration in bats could be the outcome of rapid evolutionary changes in response to specific proximal factors.

In the past it has not been possible to reconstruct the ancestral state of migration in bats as there was no existing phylogenetic "supertree" of bat species.

In light of current theories on the evolution of migration in birds [e.g., 5] and putative North American origins for bats, we use ancestral reconstruction methods to investigate if 1) migration evolved in bats as it is proposed for birds, and 2) whether migration may have appeared early in the evolutionary history of bats or whether it is a recently evolved trait.

Our results show that migration in vespertillionid bats, as indeed in all bats, is a relatively rare phenomenon that appears to have evolved independently in several lineages.

In addition, L. yerbabuenae migrates annually up to 1000 1600 km between southern Mexico and southern Arizona, which is among the longest known migration routes in bats (Wilkinson and Fleming, 1996).

Given that a recent paper has suggested that bats had a Laurasian origin, possibly in North America [15], it raises the intriguing possibility that the evolution of migration in vespertilionid bats was a response to falling temperatures and a retreat to warmer wintering climes rather than the "expansion from the tropics" that is generally viewed as the case in birds.

The equal rates transition model was the most parsimonious explanation, suggesting that loss and gain of non-migratory behavior, short-distance migration, and long-distance migration are all equally likely in bats (Figure 2).
