Seed germination experiments were conducted on six woody leguminous species which are widely used by rural inhabitants of a mountainous tropical subhumid region in southern Mexico. Conditions for optimum germination were ...
Fire causes a reduction of plant cover due to the death of several structures, especially of those that are not isolated from high temperatures; such as seeds and fruits. After a disturbance the availability of diaspores ...

Patterns of above- and below-ground biomass allocation in seedlings of nine common cloud forest (CF) tree species of western Mexico were examined under varying controlled light conditions using artificial shade houses. We ...
The effects of arbuscular mycorrhizae (AM) fungi on growth and survival of two pioneer tropical plant species were studied in a greenhouse experiment for 6 months. One, an early pioneer species (Heliocarpus appendiculatus ...

The effects of arbuscular mycorrhizae (AM) fungi on growth and survival of two pioneer tropical plant species were studied in a greenhouse experiment for 6 months. One, an early pioneer species (Heliocarpus appendiculatus ...
Ants are a very important element in and and semiarid environments, not only because of their abundance and diversity, but also because of the many ecological functions that they perform. In Mexico, Zapotitlan (Tehuacan ...

There are two types of pitahaya that are cultivated in Yucatan Peninsula of Mexico. They differ mainly in the skin color of the fruit, one of them has a red skin (Uqroo1), while the other has a light yellow skin (Uqroo2) ...
The gastropod shell utilization pattern of the hermit crab Clibanarius antillensis Stimpson 1862 was studied at Montepio, Veracruz, Mexico. Specimens were collected along the intertidal zone. All gastropod shells were ...
1. The present paper was aimed at studying the role of the neuroendocrine system, particularly the sinus gland, in the spectral sensitivity of the crayfish. 2. Using the ERG, spectral sensitivity of naive adult cryfishes ...
Land use/land cover change (LULC) is a major threat to natural protected areas worldwide. This paper explores the relationships between four estimated LULC parameters for 17 Mexican biosphere reserves (BRs) for 1993–2002 ...
The soils of montane cloud forests (MCF) are still insufficiently studied. A number of researchers report Podzols to be the main soil group for MCF ecosystems
Agroforestry is a new practice of sustainable soil use in the mountainous Sierra Sur de Oaxaca area of Mexico. Coffee is also a common cash crop grown in the region. The objective of this study was to investigate the ...
The essence of pedogenesis, as a synergetic process, consists in generation, selection, accumulation and differentiation of the solids produced in the course of bio-abiotic processes functioning within a soil body. Soil ...
We examine the effect of mulches on the soil volumetric water content (SVWC), pH, carbon (C), total and mineral (NH4 and NO3) nitrogen (N), total and bicarbonate phosphorus (P), and on the survival and relative growth rate ...
The knowledge about ants of arid zones of Mexico is very poor. For this reason we assessed the biodiversity of this taxon in 2 sites with different vegetation structure. Ten pitfall traps were placed in each site, and 2 ...
