The goal was to characterize the floral biology of the Agave gentryi kind in La Marcela, Miqihuana, Tamaulipas. The hypothesis that says that if most of the Agave kind plants are pollinated by quiropteros, then the Agave gentryi will present more production of nectar and the sugar concentration during the night, also the receptivity of the night belief. Various parameters were set for the floral biology like the antithesis of the nectar production in milligrams and the sugar concentration in Brix degrees and floral visitors. The results proved that the nectar production (1.82 milligrams per flower) and the sugar concentration (11.52 Brix degrees) increases during the night.

However, these patterns are still unstudied for many plant communities. This study aimed to evaluate the structure (species richness, Shannon's diversity index, Simpson´s dominance index, abundance of each species, average height of species, species cover (%), species composition, and indicator values) of a low thorn forest fragment and to analyze its relation with microclimate along a successional gradient. Four stages of succession were delimited by the analysis of Landsat images, in the state of Tamaulipas, northeast Mexico. Statistical models incorporated species richness, diversity indices, abundance, height, and cover, as variables for searching differences between stages, or to evaluate microclimate associations. A total of 70 species, 54 genera, and 27 families were determined. Height of tree layer was the most important variable for discrimination of the successional stages. Conserved areas differed floristically from other stages, associated mainly with the lowest values of wind speed originated by tree layer characteristics. A significant association between species and microclimate was found, being wind speed and relative humidity the most important variables. Some species, due to their high importance values and their patterns of association with microclimate, may be considered as key taxa for low thorn forest, which is a threatened semitropical community in northeast Mexico. Conserved and late successional areas account for climatic regulation of this plant community, and the importance of these forest patches may be considered when establishing biodiversity protection areas.

Therefore, it is necessary to study the areas where this orchid is distributed to understand the plant vegetation interaction. Research questions: What plant species are associated with Dichromanthus cinnabarinus? What is the degree of similarity among the plant communities with which Dichromanthus cinnabarinus is associated? Study site: Northeastern Mexico, comprehending the states of Coahuila, Nuevo Leon and Tamaulipas. Methods: The study sites were selected consider-ing the presence of Dichromanthus cinnabarinus. Regarding the study of the plant struc-ture, the tree, shrub, and herbaceous strata were obtained by the methodology of quad-rants. Data were collected in April and August 2017. The results were analyzed using the Importance Value Index (IVI) for each stratum present and a Parsimony Analysis of En-demicity (PAE) for the plant communities. Results: In the study area, a total of 33 families, 60 genera and 69 species were registered. The representative families are Asteraceae with eight species, Asparagaceae with six, Fabaceae with five, followed by Cactaceae, Poaceae and Roasaceae with four species each. Regarding endemic species, a total of 11 species distributed in nine genera were registered in the study sites. Conclusions: In northeastern Mexico, Dichromanthus cinnabarinus is found associated with Aristida adscensionis L., Agave lechuguilla Torr. Bouteloua sp., Euphorbia antisyphilitica Zucc., Agave striata var. striata (Salm-Dyck) and Rhus virens Lindh. ex A. Gray. Moreover, Dichromanthus cin-nabarinus is observed in some sites with contrasting flora, according to the resulting list of endemic species. It is important to establish priority areas for wildlife conservation in northeastern Mexico.

Microclimate is among the first modified factors after vegetation loss, effects of such disturbances are critical for species performance. However, both secondary succession and seasonality provoke further modifications in abiotic environment after disturbances. Although microclimate patterns during succession are well studied for several ecosystems, they are practically unknown for low thorn forests. In Northern Mexico, this is an endangered ecosystem characterized by harboring a high percentage of endemics. Measurement of microclimatic factors is crucial for understanding possible consequences of post-disturbance time on species inhabiting this ecosystem. This work aimed to assess seasonal variation of microclimatic patterns in a succession gradient of four categories (conserved areas, 31, 17 and four years of succession). The study area was delimited u...

Para ello, proponemos una clave dicotómica para su identificación en campo con base en terminología obtenida de literatura especializada y una asociación de caracteres fenotípicos de aves. También, reportamos la presencia de anormalidades pigmentarias en la coloración corporal y de plumaje de cinco especies de aves que han sido observadas de forma ocasional en áreas perturbadas por impacto antropogénico en Tamaulipas, México: melanismo en la tortolita mexicana (Columbina inca), aberración ino en la paloma turca (Streptopelia decaocto), aberración ino en el correcaminos norteño (Geococcyx californianus), leucismo parcial en el pijuy (Crotophaga sulcirostris) y leucismo parcial en el tordo de ojo rojo (Molothrus aeneus). Las evidencias de casos actuales sugieren un aparente aumento de especies en vida libre con variación en la pigmentación. Las causas que lo provocan aún son discutibles, por lo cual, relacionar qué factores naturales o artificiales están involucrados en estos padecimientos podrá contribuir a determinar su origen y detectar problemas a nivel de poblaciones. La clave dicotómica propuesta en la identificación de anormalidades pigmentarias puede ser una herramienta continua en contextos modernos, si se unifica la terminología empleada.

For this reason, in the last decade, large extensions of terrain have been established for its cultivation. However, much of this land has been abandoned in a short time because at the beginning it was not known that at least six years were needed before the agave could be harvested. However, when the growers wanted to reintegrate some of these crops into the productive process, their exact age and the cultural activities needed for harvesting the agave were unknown because information regarding its vegetative development relative to its age was lacking. The hypothesis of this work was: If the morphological properties reflect the development state of the population individuals, then the properties height, basal area, rosette diameter, the north, south, east and west leaf, leaves number and foliar verticil will help to characterize the age categories in Agave tequilana Weber variety azul population under cultivated conditions. To this end, six plots with plants of different ages (one to six years) were selected in the municipality of Llera, Tamaulipas, Mexico. In each plot, 60 individuals were selected at random, and their morphological properties (height, basal area, rosette diameter, northern leaf, southern leaf, eastern leaf, western leaf; number of leaves and leaf whorl) were measured. With these data, a principal component analysis was performed to determine which of these properties explains the most variation of the data. The results indicate that height and basal area are the properties that

Furthermore, secondary succession changes both resource availability and microclimatic conditions after disturbance, thus influencing species niche requirements. However, despite this importance, effects of such modifications on phytophagous insects remain almost unknown. Therefore, in this study we compared microclimatic niche parameters of leaf beetle communities in a successional gradient of low thorn forest in northeastern Mexico. A chronosequence of four categories with different succession time was delimited (conserved areas, 31, 17 and 4 years) through the analysis of Landsat satellite images (1973, 1986, 2000, 2005 and 2015). In each category, we systematically sampled leaf beetles (using sweep nets) and recorded seven microclimatic variables monthly, during the wet season of 2016 (May–October). In total, 66 species of Chrysomelidae were found, distributed in the four successional categories. Association between communities and microclimatic variables, as well as the number of species significantly related with these changes, decreased with successional time. Relative humidity, temperature and heat index were variables mainly related to these changes, and their specific contributions changed with time. Results suggest that microclimate influences the structuration of the phytophagous insect community after disturbance, but only in areas of recent succession; thus, other factors are operating in conserved areas. Therefore, secondary vegetation areas of different recovery time constitute unique microclimate niches for leaf beetle species, and as such, these need to be accounted for when delimiting conservation areas.
