MARTINEZ-CERVANTES, A. Celeste; MARTINEZ-MEYER, Enrique  e  HINOJOSA-DIAZ, Ismael A.. Ecological niche conservatism in sister species of Euglossa (Apidae: Euglossini) from Mexico and Central America. Rev. Mex. Biodiv. [online]. 2026, vol.97, e975605.  Epub 04-Fev-2026. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2026.97.5605.

Bees of the tribe Euglossini are important pollinators in the Neotropical region contributing to the reproduction of a variety of plants visited by females in search for floral resources while males are specialized pollinators of groups of orchids in their quest for aromatic chemicals, also retrieved from other sources and later used as sexual signals. Euglossa is the most diverse genus in the tribe ranging from northern Mexico to the southern parts of the Neotropical region. General phylogenetic affinities are known for several species in the genus. Here we describe and compare the ecological niche for 3 pairs of sister species of the genus Euglossa under the premise of niche conservatism, for which we found significant similarity only between sister species in the subgenus Euglossa, whereas in the other comparisons niche similarity is explained by the sympatric distributions of the species rather than by their phylogenetic relationships.
