Article
1. Plant‐pollinator interactions are fundamental to ecosystem functioning; however, the role that succession and phenology have on these interactions is poorly understood, particularly in endangered tropical ecosystems. In highly diverse ecosystems such as tropical dry forests (TDF), variation in water and food availability determines the life cycl...
Article
The biological control using organisms that inhibit growth or the appearance of pests or diseases has proven to be a successful alternative for mango disease control. In this work, in vitro analyses were carried out with Bacillus licheniformis M2–7 and B. licheniformis LYA12 strain derived from M2–7 against the phytopathogenic fungi Aspergillus ory...

The concentration of As, Pb, Cd, Zn, Fe, Mn, and Cu and the Sr and Pb isotopic compositions were determined in four species of the vascular epiphyte Tillandsia (T. caput medusae, T. ionantha, T. recurvata, and T. sp), to evaluate their capacity to biomonitor the air quality and the sources of lithogenic particles and toxic elements in a severely co...
Article
Full-text available
Network analysis is a powerful tool to understand community‐level plant‐pollinator interactions. We evaluate the role of floral visitors on plant fitness through a series of pollination exclusion experiments to test the effectiveness of pollinators of an Ipomoea community in the Pacific coast of México, including: (1) all flower visitors, (2) visit...
Article
Full-text available
It has been proposed that species‐rich insect communities and species turnover across landscapes enhance the pollination efficiency of crops through complementarity, where both the dominant and less abundant species contribute to reaching a yield threshold from pollination. Alternatively, fluctuations in the most abundant pollinator species, rather...
Article
Full-text available
Fragmentation of natural habitats generally has negative effects on the reproductive success of many plant species; however, little is known about epiphytic plants. We assessed the impact of forest fragmentation on plant–pollinator interactions and female reproductive success in two epiphytic Tillandsia species with contrasting life history strateg...
Article
Full-text available
Most hummingbird species are distributed in tropical lowlands and mountains with few species reaching the alpine environments of high mountain peaks. Field surveys were conducted in nine alpine sites across four of the highest volcanoes in central Mexico for three years to document hummingbird occurrence, habitat use, and some aspects of behavior....
Article
Full-text available
In a recent literature review, we demonstrated that the evolution of floral traits is driven by adaptation to the most effective pollinators. In a critique of this study, Ollerton et al. 2015 claimed there were apparent flaws with data collection, analyses and interpretation of results. We disagree since many of OLT´s observations and recommendatio...
Chapter
Full-text available
Convergent evolution of floral traits driven by pollinators has resulted in floral syndromes shared among different plant lineages. However, the flowers of many plant species are often visited by different pollinator groups, which apparently contradict the idea of syndromes. Here, we demonstrate that the most efficient pollinators consistently corr...

Full-text available
1The evolution of self-pollination has long been considered an adaptive strategy to cope with low or variable pollinator service; however, alternative reproductive strategies, such as generalized pollination (>1 pollinator functional group), may also ensure plant reproductive success in environments with inadequate pollinator visitation.2Island-mai...
Article
Full-text available
Co-flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant-pollinator networks from 28 studies representing diverse biomes worldwide. We show that the potential for one plant species to influence another indirectly via shared pollinat...
Article
In subdioecious populations, functional female, male and hermaphrodite individuals coexist. Subdioecy may be a transitional state towards dioecy or a breakdown of dioecy, although lability in sex expression may maintain subdioecy as a stable condition. To better understand the ecological aspects involved in sex ratio dynamics and breeding system ev...
Article
Full-text available
The idea of pollination syndromes has been largely discussed but no formal quantitative evaluation has yet been conducted across angiosperms. We present the first systematic review of pollination syndromes that quantitatively tests whether the most effective pollinators for a species can be inferred from suites of floral traits for 417 plant specie...
Chapter
Full-text available
Although under threat from natural and human disturbance, tropical dry forests are the most endangered ecosystem in the tropics, yet they rarely receive the scientific or conservation attention they deserve. In a comprehensive overview, Tropical Dry Forests in the Americas: Ecology, Conservation, and Management examines new approaches for data samp...
Conference Paper
Background/Question/Methods Vascular epiphytes establish obligate, commensalistic interactions with their host plants (phorophytes). The fact that epiphytes have long life cycles, limited dispersal and depend on phorophytes, makes them one of the most vulnerable plant growth forms. Anthropogenic disturbances such as deforestation for land use con...
Article
Full-text available
A central issue in ecology is the understanding of the establishment of biotic interactions. We studied the factors that affect the assembly of the commensalistic interactions between vascular epiphytes and their host plants. We used an analytical approach that considers all individuals and species of epiphytic bromeliads and woody hosts and non-ho...
Conference Paper
Background/Question/Methods The biodiversity and level of endemism of tropical dry forests (TDF) in Mexico is high for many taxa and have been affected dramatically by human activities. The Chamela-Cuixmala Biosphere Reserve is one of the few natural reserves that protect TDF in Mexico. Around the reserve, vegetation cover has been fragmented and...
Article
Full-text available
Understanding tropical forest succession is critical for the development of tropical forest conservation strategies worldwide, given that tropical secondary forests can be considered the forests of the future. Tropical dry forests (TDF) are among the most threatened tropical ecosystems, there are more secondary forests and forest restoration effort...
Article
Full-text available
Studies of pairwise interactions have shown that an alien plant can affect the pollination of a native plant, this effect being mediated by shared pollinators. Here we use a manipulative field experiment, to investigate the impact of the alien plant Impatiens glandulifera on an entire community of coflowering native plants. Visitation and pollen tr...
