22 Ιουλ 2003 · Isolating mechanisms are characteristics of species that reduce or prevent successful reproduction with members of other species. Viewed genetically, they are characters that act as barriers to...
Reproductive isolation - Wikipedia. The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They prevent members of different species from producing offspring, or ensure that any offspring are sterile.
1 Νοε 2023 · Even when populations of different sympatric species are in contact and breed at the same time, the individuals of one species may reject or fail to recognize individuals of other species as mating partner. This is called sexual isolation or ethological isolation.
6 Αυγ 2020 · Ethological isolation for preference across all pollinators (RI ethoP) was thus stronger for exposed than for sunken organs. For P. veris, large bees and bee flies performed fewer conspecific than heterospecific transitions.
29 Μαρ 2012 · The present review documents an overview of speciation mediated through behavioural incompatibility in different species groups of Drosophila with particular reference to the models proposed on the basis of one-sided ethological isolation to predict the direction of evolution.
Ethological isolation is often complemen-. tary to mechanical isolation (e.g., in Aq-uilegia, Polygala, Penstemon, Pedicu-laris), confirming the usefulness of the collective mode, floral isolation. Etho-logical isolation plays a primary role in several groups (Hedysarum, Cercidium, Phlox, Ophrys).
