Introduction
In the cloud forest, we studing the ecology of epiphytic bromeliads. 1) We monitored the ability to catch and retain water in epiphytic bromeliads rosettes. 2) We are studying the contribution of macroinvertebrates present in the tank bromeliads on the release of nutrients, and their effect on plant growth. 3) We evaluate the potential of hybridization most abundant epiphytic bromeliads after disturbances. We study how environmental factors affect ecological productivity in vanilla plantations.

Article
Tropical montane cloud forest is one of the most threatened ecosystems, in central Veracruz, Mexico. Within this ecosystem, terrestrial orchids are strongly dependent on forest conditions and may be sensitive to environmental change. We applied field surveys of abiotic and biotic factors associated with the presence of the terrestrial orchid Cyclop...

Aunque se espera que los síndromes de polinización reflejen la adaptación a los polinizadores primarios, los rasgos del síndrome pueden no excluir a polinizadores secundarios, que también pueden desempeñar un papel en la evolución floral 8. Por ello es importante determinar la efectividad de los polinizadores (p.ej. polen depositado, removido y sem...

The Island of Cozumel, located in the Mexican Caribbean, has been granted several protection denominations because of its high biodiversity. However, despite these efforts, several invasive species have been found on the island. Of these, published studies indicate that two plant species are invasive in beach and coastal dune vegetation, but inform...

Background Forestry management modifies the diversity, structure, and functioning of intervened forests. Timber extraction reduces tree density and basal area, leading to changes in the communities of vascular epiphytes. The objective of this study was to evaluate the diversity and biomass of vascular epiphytes in Quercus trees remaining in two pin...

La deforestación y fragmentación son consideradas amenazas para la biodiversidad. Ambos procesos tienen efectos negativos en la función y dinámica de los sistemas ecológicos a diferentes escalas espaciales y temporales. Se analizó el cambio de uso de suelo y la fragmentación del paisaje en la región central de Veracruz, México, para los años 1989,...

Intraspecific variation in floral traits, such as nectar, could lead to differences in the identity and pollinator effectiveness of visitors between populations of a flowering plant. We studied the bat-pollinated bromeliad species Pseudalcantarea viridiflora to determine whether there are differences in the identity of its pollinators and in its ne...

Bromeliads are the most abundant litter-trapping plants in Neotropical forest canopies. By intercepting litter, bromeliads obtain and retain nutrients before they reach the pedosphere. Here, we analyzed the litter captured and stored by tank bromeliads (TB) in five different forests along an elevation gradient in Mexico. Among those forests, carbon...

The mating system of plants widely distributed can change in native range but also in non-native habitats. Oenothera drummondii, native to the coastal dunes of the Gulf of Mexico, has been introduced to Europe, Africa, Asia and Oceania. Hand self- and cross-pollination were performed to determine compatibility and to compare fruit set, fruit weight...

Timber extraction directly affects forest structure by opening the canopy, reducing the density and volume of dominant species, and transforming the composition, diversity, and functioning of the forest. We analyze the richness, diversity, and basal area of tree species in a pine-oak montane forest under two stages of the Silvicultural Development...

The illegal collection of wild orchid pseudobulbs is a conservation problem, but little is known about this practice's consequences in orchid individuals. In some regions of Mexico, the latest two pseudobulbs of Laelia autumnalis plants are collected and traded, including the inflorescence. We: 1.- determined the nutrient content of pseudobulbs/lea...
Article
Plant species with specialized pollination and wide geographic distribution can show variation in the size of floral traits related to environmental local conditions. We studied the floral traits of native and non-native populations of Oenothera drummondii under greenhouse conditions to test if their variation is related to latitude, or their nativ...

Buzz-pollinated plants are an essential source of pollen for a significant portion of local bee communities. Buzz pollination research has focused on studying the properties of bee buzzes and their implications on pollen release, morphological specialization of flowers, and the reproductive ecology of buzz-pollinated plants. In contrast, diversity...

• Tropical trees accommodate a high co‐occurrence of ant species, mainly due to the high diversity of microhabitats available. However, a few ant species are highly abundant, dominating resources and defending territories in tree canopies. Although arboreal ants have been studied extensively, little is known about the structural drivers of ant spat...

Plant litter decomposition is a key ecological process that is mostly studied at the forest floor. However, decomposition generally starts in the canopy. In this study, we evaluated the effect of litter composition and climate on the initial phase of decomposition in the soil and two contrasting types of canopy microsites along an elevational gradi...

In the Bromeliaceae, hybrids have been engineered for horticultural purposes; in addition, hybrids have been observed in natural habitats. We investigated the hybridization potential of three sympatric species of Tillandsia inhabiting secondary forests and shaded coffee plantations in the central mountains of Veracruz, Mexico. The studied species (...

Beaches and foredunes are characterized by being exposed to harsh environmental restrictions mainly due to salt spray, burial by sand and occasional storms. In response to this, plant species from these habitats have adaptations that allow them not only to survive in these environments, but also to recover after the impact of disturbances such as s...

Discussion of the vertical stratification of organisms in tropical forests has traditionally focused on species distribution. Most studies have shown that, due to differences in abiotic conditions and resource distribution, species can be distributed along the vertical gradient according to their ecophysiological needs. However, the network structu...

Predation is one of the main interactions between organisms and one of the primary selective agents for their survival. Both prey and predators have developed different strategies and characteristics that allow them to be conspicuous or go undetected. In sit and wait predators, their shape and appearance are important factors that allow them to rem...

One of the major threats to the diversity of coastal dunes is the expansion of invasive species, such as Oenothera drummondii subsp. drummondii (Onagraceae). In southwestern Spain, we studied the impact of this American invasive on community structure and composition along a beach-dune gradient (beach, foredune, and inland dunes). Differences in de...

Pollinators can be a limited resource and natural selection should favor differences in phenotypic characteristics to reduce competition among plants. Bats are important pollinators of many Neotropical plants, including the Bromeliaceae; however, the pre-pollination mechanisms for isolation among sympatric bat-pollinated bromeliads are unknown. Her...

It has been hypothesized that the fitness of selfed progeny must be lowered by inbreeding depression. Most research into the breeding systems of orchids shows a similar fruit set from outcrossing and self-pollination, but few studies have measured seed production and viability. In five populations of Laelia autumnalis, in central México, we studied...

Many animals use body coloration as a strategy to communicate with conspecifics, prey, and predators. Color is a trade-off for some species, since they should be visible to conspecifics but cryptic to predators and prey. Some flower-dwelling predators, such as crab spiders, are capable of choosing the color of flowers where they ambush flower visit...

Most plants that inhabit in ant-gardens (AGs) are cultivated by ants. Some orchids occur in AGs, however, it is unknown if their seeds are dispersed by AG ants, because most of the orchid seeds are tiny and dispersed by wind. We performed in situ seed removal experiments, in which we simultaneously provided Azteca gnava ants with seeds of three AG...
