Host-plant sex and phenology of Kunth interact to influence arthropod communities.

Intraspecific variation in plants is expected to have profound impacts on the arthropod communities associated with them. Because sexual dimorphism in plants is expected to provide consistent variation among individuals of the same species, researchers have often studied the effect it has on associated arthropods. Nevertheless, most studies have focused on the effect of sexual dimorphism in a single or a few herbivores, thus overlooking the potential effects on the whole arthropod community.

Genetic variation in foundation species governs the dynamics of trophic interactions.

Various studies have demonstrated that the foundation species genetic diversity can have direct effects that extend beyond the individual or population level, affecting the dependent communities. Additionally, these effects may be indirectly extended to higher trophic levels throughout the entire community. is an oak species with characteristics of foundation species beyond presenting a wide geographical distribution and being a dominant element of Mexican temperate forests.

Diversity and Resource Use Patterns of Anthophile Insects in Cuatro Ciénegas, Coahuila, Mexico.

Bees and flies are the main pollinators responsible for the maintenance of plant diversity and crop production. Studies of pollinator communities have focused on bees; however, community structures may vary among groups of pollinators. We describe and compare the diversity and resource use patterns of six Apoidea and two Diptera anthophile families in Cuatro Ciénegas in the northeast of Mexico.

New records of bee flies (Diptera, Bombyliidae) from Cuatro Ciénegas, Coahuila, Mexico.

Forty one new records of species of Bombyliidae are reported for Coahuila in northeastern Mexico. Nine of these species are reported for the first time for the country. The specimens were collected in the Cuatro Ciénegas Basin and Sierra La Madera mountains during 2007-2013.

Phenotypic plasticity of the basidiomata of Thelephora sp. (Thelephoraceae) in tropical forest habitats.

Phenotypic plasticity in macroscopic fungi has been poorly studied in comparison to plants or animals and only general aspects of these changes have been described. In this work, the phenotypic variation in the basidiomata of Thelephora sp. (Thelephoraceae) was examined, as well as some aspects of its ecology and habitat, using 24 specimens collected in the tropical forests of the Chamela Biological Station, Jalisco, Mexico.
