Climate change in forest ecosystems: A field experiment addressing the effects of raising temperature and reduced rainfall on early life cycle stages of oaks
(Elsevier, 2018)"Higher temperatures and reduced rainfalls that are expected with the advance of climate change can impair the emergence and establishment of tree seedlings in forest ecosystems. These climatic changes can also decrease ... -
Comunidades de roedores nocturnos en un ecotono de matorrales micrófilos y zacatal gipsófilo en San Luis Potosí, México
(Instituto de Biología, Universidad Nacional Autónoma de México, 2008)"En el presente estudio se compara la abundancia y riqueza entre los roedores nocturnos de un zacatal gipsófilo y los de 3 matorrales micrófilos, en el norte de San Luis Potosí. Los muestreos se llevaron a cabo en sitios ... -
Dynamics of short-term ecosystem carbon fluxes induced by precipitation events in a semiarid grassland
(European Geosciences Union, 2023)Infrequent and small precipitation (PPT) events characterize PPT patterns in semiarid grasslands; however, plants and soil microorganisms are adapted to use the unpredictable small pulses of water. Several studies have ... -
Effects of five Lacandon Maya agroforestry trees on soil nematode trophic group composition
(Springer, 2018)"The Lacandon Maya have managed their lands in Chiapas, Mexico for hundreds of years without long-term soil degradation by applying their traditional swidden agroforestry system. Lacandon land managers plant and care for ... -
Factores que influyen en la ocupación de hábitat en la temporada de reproducción del gorrión de Worthen (Spizella wortheni) en el Altiplano Potosino
(2019-09-17)"El Gorrión de Worthen (Spizella wortheni), es una especie endémica y amenazada del Altiplano Mexicano que se asocia a pastizales naturales y matorrales. Su rango de distribución ha disminuido significativamente en los ... -
Infection intensity shapes specialization and beta diversity of haemosporidian–bird networks across elevations
(Wiley, 2023)Host–parasite distribution and interactions depend on geography, evolutionary associations, species composition, and their response to environmental variables. In this sense, host specificity as a key parasite's life history ... -
Landscape composition influences abundance patterns and habitat use of three ungulate species in fragmented secondary deciduous tropical forests, Mexico
(Elsevier, 2015)"Secondary forests are extensive in the tropics. Currently, these plant communities are the available habitats for wildlife and in the future they will possibly be some of the most wide-spread ecosystems world-wide. To ... -
Mexico ants: incidence and abundance along the Nearctic-Neotropical interface
(Wiley, 2019)"Mexico is one of the most biodiverse countries in the world, with an important proportion of endemism mainly because of the convergence of the Nearctic and Neotropical biogeographic regions, which generate great diversity ... -
Patterns of Richness and Endemism in the Gypsicolous Flora of Mexico
(MDPI, 2023)Gypsum soils occur around the world, mainly in arid regions. These harsh environments promote unusual flora with high degrees of endemism. Mexico has extensive gypsum outcrops, but their flora has been poorly studied. ... -
Predicting geographic distribution and habitat suitability of Opuntia streptacantha in paleoclimatic, current, and future scenarios in Mexico
(Wiley, 2023)Mexican territory is one of the centers of origin and dispersion of the genus Opuntia, where several of its species have been an important plant resource for people in arid and semiarid zones. Opuntia streptacantha is ... -
Rangeland systems in developing nations: conceptual advances and societal implications
(Springer, 2017)"Developing-country rangelands are vast and diverse. They are home to millions who are often poor, politically marginalized, and dependent on livestock for survival. Here we summarize our experiences from six case-study ... -
RecruitNet: A global database of plant recruitment networks
(Wiley, 2023)Plant recruitment interactions (i.e., what recruits under what) shape the composition, diversity, and structure of plant communities. Despite the huge body of knowledge on the mechanisms underlying recruitment interactions ... -
Seasonal Precipitation Legacy Effects Determine the Carbon Balance of a Semiarid Grassland
(Wiley, 2019)"Semiarid grasslands are water‐limited ecosystems where precipitation (PPT) controls the onset and duration of the growing season; however, this variable does not fully explain interannual variability of productivity at ... -
Shopping for Ecological Indices? On the Use of Incidence-Based Species Compositional Similarity Measures
(MDPI, 2022)"β-diversity has been under continuous debate, with a current need to better understand the way in which a new wave of measures work. We assessed the results of 12 incidence-based β-diversity indices. Our results of gradual ... -
Soil fungal abundance and plant functional traits drive fertile island formation in global drylands
(Wiley, 2018)"Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These fertile islands are major drivers of dryland ecosystem structure and functioning, yet ... -
The contribution of dew and fog in the water balance of a continental semiarid grassland ecosystem
(2020-01)"In arid and semiarid regions, water scarcity plays an important role in determining the plant distribution, density, cover and productivity; it also controls many other biological processes. In these regions, different ...
