Abstract. The sweetpotato whitefly Bemisa tabaci (Gennadius) and the greenhouse whitefly Trialeurodes vaporariorum (Westwood) are considered as species of economic importance of crops worldwide. These species primarily cause damage to plants through the transmission of Begomovirus in the case of B. tabaci
and Crinivirus in the case of T. vaporarior...

The maize agroecosystem has a great diversity of insect pests, the most important being those of the order Lepidoptera, such as the armyworm Spodoptera frugiperda and the earworm Helicoverpa zea. Populations of these insects are regulated by natural enemies found in corn. Of these natural enemies, the parasitoids stand out, which are mainly of the...

The decline of freshwater species diversity is
a worldwide phenomenon but it is especially
pronounced in arid regions such as in the
Chihuahuan Desert of Coahuila and Durango,
Northern Mexico. There are few historical data
on the distribution but no data on extinctions
of Mexican freshwater gastropods. In such
cases, paleontological data can be ver...

It has frequently been reported that species with strong niche conservatism will not be able to adapt to new climatic conditions, so they must migrate or go extinct. We have evaluated the shifts in climatic niche occupation of the species Astrophytum coahuilense and its potential distribution in Mexico. We understand niche occupation as the geograp...

Uno de los procesos de la biología evolutiva más enigmáticos y controvertidos es hasta la fecha la especiación. Hoy existen dos modelos principales, conceptualmente distintos, sobre los patrones evolutivos: el Gradualismo y el Equilibrio Puntuado. Para ambos modelos existen evidencias paleobiológicas y los moluscos jugaron en este discurso evolutiv...
