Testing the evolutionary theory of inversion polymorphisms in the yellow monkeyflower (Mimulus guttatus).

Chromosomal inversions have been implicated in a remarkable range of natural phenomena, but it remains unclear how much they contribute to standing genetic variation. Here, we evaluate 64 inversions that segregate within a single natural population of the yellow monkeyflower (Mimulus guttatus). Nucleotide diversity patterns confirm low internal variation for the derived orientation (predicted by recent origin), elevated diversity between orientations (predicted by natural selection), and localized fluctuations (predicted by gene flux).

Assessing the predictive value of morphological traits on primary lifestyle of birds through the extreme gradient boosting algorithm.

The relationship between morphological traits and ecological performance in birds is an important area of research, as it can help us to understand how birds are able to adapt and how they are affected by changes in their environment. Many studies have investigated the relationship between morphological traits and certain aspects of the performance and ecological niche of these animals. However, the relationship between morphological traits and the primary lifestyle of birds has not previously been explored.
