“…The former is characterized as poorly developed soil, with low organic matter content, and is often shallow; while the latter are young, acidic, and nitrogen-rich soils. Coniferous forests of the region are relatively rich floristically [27]. This region is one of the most important timber reserves in Mexico, supplying more than 25% of the national timber, and it is therefore relevant for sustainable forestry in the country [31].…”

“…This region has one of the highest conifer species richness in the world [27], where they grow in climatically and topographically contrasting environments. The main conifers include a diverse range of species: from Pinus cembroides Zucc., a species representative of low elevation and dry locations, to Cupressus lusitanica Mill., a species dominant in humid sites [27]. Here we compare a xeric habitat where trees grow under marginal environmental conditions (e.g., low precipitation and high evapotranspiration rates) with a mesic habitat characterized by higher productivity and more favorable climate conditions such as higher rainfall and lower evapotranspiration rates [27,28].…”

Drought is a major constraint of forest productivity and tree growth across diverse habitat types. In this study, we investigated the drought responses of four conifer species growing within two locations of differing elevation and climatic conditions in northern Mexico. Two species were selected at a mesic site (Cupressus lusitanica Mill., Abies durangensis Martínez) and the other two species were sampled at a xeric site (Pinus engelmannii Carr., Pinus cembroides Zucc.). Using a dendrochronological approach, we correlated the radial-growth series of each species and the climatic variables. All study species positively responded to wet-cool conditions during winter and spring. Despite the close proximity of species at a mesic site, A. durangensis had high responsiveness to hydroclimatic variability, but C. lusitanica was not responsive. At the xeric site, P. engelmannii and P. cembroides were very responsive to drought severity, differentiated only by the longer time scale of the response to accumulated drought of P. engelmannii. The responsiveness to hydroclimate and drought of these tree species seems to be modulated by site conditions, or by the functional features of each species that are still little explored. These findings indicate that differentiating between mesic and xeric habitats is a too coarse approach in diverse forests with a high topographic heterogeneity.

“…De norte a sur se produce una transición desde una zona de clima Mediterráneo, que alcanza en la Península de Baja California su límite meridional holártico, a otra donde se encuentran los desiertos más áridos de Norteamérica (Peinado et al, 1995a). Desde estos desiertos se entra en otra zona de bosques tropicales con lluvias de verano, los cuales alcanzan en la vertiente pacífica mexicana su límite septentrional de distribución en el hemisferio occidental (Brown et al, 1998;Van Devender et al, 2000;González-Elizondo et al, 2012). Hacia el extremo meridional de la franja de estudio los bosques anteriores se imbrican con los bosques de lluvia tropicales; otras formaciones típicamente tropicales, los manglares, alcanzan en las costas mexicanas de Baja California las latitudes más septentrionales dentro del reino Holártico (Peinado et al, 2008).…”

Clasificación bioclimática de la vertiente del pacífico mexicano y su relación con la vegetación potencial

En este trabajo se abordan las relaciones entre el clima y la vegetación en el territorio de la vertiente del Pacífico Mexicano, considerada como una franja de 100 km de ancho que desde el litoral se extiende hacia tierra adentro y cuyos extremos norte y sur coinciden con la frontera de México con los Estados Unidos de América y con Guatemala respectivamente. Las relaciones fueron establecidas a partir del análisis bioclimático efectuado con los datos de precipitación y temperatura de 691 estaciones meteorológicas existentes en el área de estudio. La diagnosis bioclimática permitió identificar los macrobioclimas Mediterráneo y Tropical, los bioclimas Mediterráneo Pluviestacional Oceánico, Mediterráneo Xérico Oceánico, Mediterráneo Desértico Oceánico, Mediterráneo Hiperdesértico Oceánico, Tropical Pluvial, Tropical Pluviestacional, Tropical Xérico, Tropical Desértico y Tropical Hiperdesértico, y 30 isobioclimas. Los muestreos de campo se dirigieron hacia la caracterización fisionómica y florística de la vegetación natural potencial de las diferentes unidades bioclimáticas, estableciendo así los principales elementos diagnósticos (bioindicadores y fisionómico-estructurales) de la secuencia bioclimática a lo largo del gradiente latitudinal.

Mesoscale convective systems (MCSs) are frequent, but understudied, components of the warm season climatology in northwestern Mexico. This study provides an update of previous research on convective development and examines MCS life cycle, structure, and motion from July through September. It focuses on a region south of the North American monsoon core and, from 2009 to 2018 satellite observations, on patterns of cloud tops higher than 10 km above sea level. The diurnal cycle of convection shows cells initiating in the early afternoon over the Sierra Madre Occidental mountains and becoming better organized over the next few hours. These features typically move westward, grow upscale to reach maximum vertical extent near local sunset, and weaken during the night. However, there is a distinct region of deep convection over and off the coast of Nayarit (20-23 N), in the Pacific Ocean, that remains active through the night and into the early morning, producing heavy rainfall and frequent lightning. Occasionally, the inner structure of these MCSs can move across the Gulf of California and reach the southern Baja California Peninsula. One particular long-lived, fast-moving MCS from July 23 and 24, 2014 was selected for in-depth analysis, because it was associated with weather conditions that included unusual precipitation and extreme winds. The MCS caused damage from sustained winds of tropical-storm strength and an intense gust front in the Los Cabos area, in the southern tip of the peninsula. This extraordinary MCS developed in the most unstable and humid environment recorded during the 1976-2018 period, and was supported by a collocated upper-level, inverted trough and a lower-troposphere tropical wave. We also found that the 10 most unstable conditions have all occurred after 2011, possibly indicative of a trend toward more frequent and favourable environments to spawn MCSs over the Gulf of California entrance.
