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...

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...
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...
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...
Chapter
Full-text available
Over the last two decades several studies have shown that plant species of contrasting life-forms ranging from small herbs to large trees may experience a decline in reproductive success following habitat fragmentation and population disruption (Bawa 1990; Aizen and Feinsinger 1994; Aguilar et al. 2006). Such outcome has been shown for many plants...
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
We studied the relationship between two macro-scale environmental factors (i.e., rainfall, temperature) and the arrival of Bam Swallows (Hirundo rustica) to a Mexican Neotropical city in the past 13 years (1997-2009). Temperature was not related to arrivals, but February rainfall in Mexican wintering lands (one month prior to arrival date) showed a...
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...
