Endogenous Plant Cell Wall Digestion: A Key Mechanism in Insect Evolution
TLDR
The evidence reveals that the symbiotic-independent mechanism may be the ancestral mechanism for PCW digestion in insects and suggests that changes in the composition of lignocellulolytic complexes were involved in the evolution of feeding habits and diet specializations in insects, playing important roles in the Evolution of plant-insect interactions and in the diversification of insects.

Diversity of gall‐inducing insects in a Mexican tropical dry forest: the importance of plant species richness, life‐forms, host plant age and plant density
TLDR
A significant positive correlation between G II species richness and plant species richness in both deciduous and riparian habitats is found, suggesting that radiation of GII species may be associated with plant species species richness.

Variation in leaf trichomes of Wigandia urens: environmental factors and physiological consequences.
TLDR
Seasonal and environmentally induced variation in the type and frequency of leaf trichomes of Wigandia urens (Ruiz & Pavón) Kunth (Hydrophyllaceae) was studied and smooth leaves had higher transpiration rates than bristly leaves at both exposed and shaded sites.

ECOLOGICAL CORRELATES OF REPRODUCTIVE TRAITS OF MEXICAN RAIN FOREST TREES
TLDR
Flower and fruit morphological traits, sexual systems, and tree guilds are related in a comprehensive way, and a flow model based on data from this study is presented.

Morphological and RAPD analysis of hybridization between Quercus affinis and Q. laurina (fagaceae), two Mexican red oaks.
TLDR
Foliar variation followed a partially congruent pattern, but Q. laurina-like morphology predominated in some of the genetically intermediate populations, consistent with a hypothesis of secondary contact between the two oak species that has resulted in some differential introgression among markers.

The Effects of Domestication ofBrassicaandPhaseoluson the Interaction between Phytophagous Insects and Parasitoids
TLDR
Results from two studies show that, overall, herbivore and parasitoid performance was higher on cultivated plant species than on wild species, and choice experiments revealed that parasitoids were more attracted to cultivars than to related wild plants.

Interspecific gene flow in a multispecies oak hybrid zone in the Sierra Tarahumara of Mexico.
TLDR
The Bayesian admixture analysis found that three main genetic clusters best fitted the data, with good correspondence of reference populations of each species to one of the genetic clusters, but various degrees of admixture evidenced in populations from the contact area.

Sources of Resistance to Whitefly (Bemisia spp.) in Wild Populations of Solanum lycopersicum var. Cerasiforme (Dunal) Spooner G.J. Anderson et R.K. Jansen in Northwestern Mexico
TLDR
A significant negative effect of whitefly incidence along the growing season upon plant growth rate (number of branches and height) and fruit production was detected, suggesting that trichomes deter or limit the establishment of whiteflies.

Conservation Genetics of the East Pacific Green Turtle (Chelonia mydas) in Michoacan, Mexico
TLDR
Estimates of annual effective female population size of 1.3 × 103, in spite of being an order of magnitude below historical records, appear to be sufficient to allow recovery of this population without significant loss of genetic diversity.

Genetic Structure of Wild and Domesticated Populations of Capsicum annuum (Solanaceae) from Northwestern Mexico Analyzed by RAPDs
TLDR
The considerable genetic distances among cultivars as well as the high number of diagnostic bands per cultivar suggest that genetic changes associated with domestication could have resulted from artificial selection intervening in different directions, but the inclusion of more domesticated samples might clarify the nature of distinctions detected here.
