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 ...

The authors used the reverse hemolytic plaque assay to investigate whether single retinal and optic lobe cells of juvenile and adult crayfish secrete crustacean hyperglycemic hormone (CHH) and whether the secretion rate ...

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 ...
The importance of space as an ecological factor is an emerging paradigm in community ecology, particularly as a driving force of biodiversity patterns. We analysed β-diversity linked to spatial structure in four communities ...

Analyzing the relationship between the spatial structures of environmental variables and of the associated seedling and sapling communities is crucial to understanding the regeneration processes in forest communities. The ...
1. Patches of Primula vulgaris occur across a range of light conditions within forests. To understand how light affects the stages of the life cycle involved in reproduction and recruitment, several fecundity-related ...
