1. Density-and distance-dependent (DDD) mechanisms are important determinants of plant reproductive success (PRS). Different components of sequential PRS can operate either in the same or in different directions and thus reinforce or neutralize each other, and they may also operate at different spatial scales. Thus, spatially explicit approaches ar...
Background and aims:
Nursery pollination is a highly specialized interaction in which pollinators breed inside plant reproductive structures. Pollinator occupancy of host plants often depends on plant location, flowering synchrony and sex. The nursery pollination system between the dioecious dwarf palm Chamaerops humilis (Arecaceae) and the host-s...
Premise of research. Plant aggregation and pollen origin can profoundly influence pollination success, as measured by fruit initiation and development. The effect of these variables should be more significant in plants with highly specialized pollination systems, as the pool of potential pollinators is assumed to be smaller than in plants with gene...
The nature and the strength of plant‐frugivore interactions often vary along an antagonism–mutualism continuum and are highly influenced by the local ecological context (e.g. level of environmental disturbances). However, little is known concerning how the local ecological setting where plant–frugivore interactions take place affects the seed dispe...
Range expansion in plant populations, especially at the colonization front, can be either limited by disproportionately large effects of antagonistic interactions or facilitated by their release. How the strength of antagonistic interactions changes along successional gradients during range expansion is still poorly documented, especially when dive...
Reportamos el redescubriento del murciélago cara rayada mayor (Vampyrodes major) en el estado de Tabasco, México, después de 60 años. Los registros se basan en dos individuos capturados con redes de niebla dentro del área natural protegida Cañón del Usumacinta, municipio de Tenosique. Éstos registros confirman su procedencia en el estado y represen...
• Reproductive isolation is a necessary condition for plant domestication in their domestication centre where crops co‐occur with their wild progenitors. However, the identification of reproductive barriers and their relative contribution to reproductive isolation have been overlooked in plants under domestication.
• We assessed pre‐ and post‐polli...
Chaya (Cnidoscolus aconitifolius) (Mill.) I.M. Johnst is a neglected and underutilized crop, cultivated clonally by the Maya from pre-Hispanic times to the present in their home gardens for their own consumption. Like other crops in the early stages of domestication, cultivated chaya co-occurs with its wild relatives, however, the degree of domesti...
Dentro de la familia de las cactáceas existe un gran número de especies que han desarrollado una relación mutualista con hormigas a través de estructuras extraflorales dedicadas exclusivamente a la producción de néctar. En esta interacción las hormigas visitan la plantas para obtener alimento y actúan agresivamente hacia los herbívoros que intentan...
Throughout Europe, increased levels of land abandonment lead to (re)colonization of old lands by forests and shrublands. Very little is known about the spatial pattern of plants recolonizing such old fields. We mapped in two 21–22-ha plots, located in the Doñana National Park (Spain), all adult individuals of the endozoochorous dwarf palm Chamaerop...
La dispersión de semillas representa el final del ciclo reproductivo de las plantas, que conlleva al reclutamiento de una nueva generación de plantas en una zona más o menos lejana. Una de las estrategias de dispersión más extendida en los hábitats templados es la endozoocoria, en la que las plantas ofrecen frutos carnosos para atraer a vertebrados...
Los sistemas de polinización mediados por insectos están determinados por la disponibilidad espacio-temporal de los recursos florales. En los sistemas nursery pollination en los que los polinizadores utilizan las estructuras reproductivas de las plantas para completar su ciclo de vida, se espera que esta dependencia también ocurra. En esta investig...
The sea lamprey (Petromyzon marinus linnaeus, 1758) has a vast distribution area, including both shores of the Northern atlantic and the Mediterranean sea. It is commonly assumed to be present in Morocco, but the only specific records of the sea lamprey in the country come from the first half of the 20th and are exclusive to the atlantic coast. Her...
Cincuenta años después de su creación, ¿qué se investiga actualmente en la Estación Biológica de Doñana? Ahora hay técnicas de estudio muy avanzadas, el ámbito de actuación abarca el mundo entero y, por supuesto, se han incorporado nuevos científicos. Pero el interés por escudriñar la biodiversidad sigue vigente.
It has been suggested that there is a geographic dichotomy in the pollination systems of chiropterophilous columnar cacti: in intra-tropical areas they are pollinated almost exclusively by bats, whereas in extratropical areas they are pollinated by bats, birds and bees. However, currently the studies are clumped both taxonomically (mainly Pachycere...
One of the most important tools for conservation biology and planning management is the
detailed knowledge of ecologic and geographic distribution of the native species. The current
geographic and ecological distribution of the species allows understand the evolutionary and
ecologic constraints for the adaptation, fitness and survival of the specie...
Myrmecochory sensu stricto is uncommon in Neotropical forests. In these ecosystems the role of ants as secondary dispersers of non-myrmecochorous seeds is well known, however, the primary dispersal of this type of seed by ants has been poorly documented. Only a few anecdotal observations scattered throughout the literature report the removal of the...

- Comparar la estructura y el funcionamiento de las redes de dispersión de semillas por murciélagos en distintos escenarios de intervención antrópica
- Indagar sobre la percepción que sobre los quirópteros y el servicio ecosistémico de dispersión de semillas tienen ejidatarios de la comunidad El Bejucal, Tabasco.
To evaluate the impact of climate change and deforestation on the structure of the biotic community (centered on frugivorous mammals, the plants that make up their food nucleus and their predators) and their effects on the first and second order interaction networks that they establish among themselves, through the analysis of recent changes in the distribution of target species and projections to future climate scenarios in the middle and upper Usumacinta basin.
