Summary Density‐ and distance‐dependent ( DDD ) mechanisms are important determinants of plant reproductive success PRS ). Different components sequential can operate either in the same or different directions thus reinforce neutralize each other, they may also at spatial scales. Thus, spatially explicit approaches needed to detect such complex effects across multiple To reveal early Iberian pear Pyrus bourgaeana sampled over three consecutive years, we used marked point pattern analysis....

Abstract Ecologists have long recognized that seed dispersal mutualisms trigger natural regeneration and range expansion of animal‐dispersed trees. Yet we lack empirical studies addressing whether frugivore activity influences founder effects, which reduce genetic diversity at the colonization front expanding populations. Here, evaluate contribution, from both demographic perspectives, animal frugivores dispersing seeds across an gradient. We used DNA barcoding for identification highly...

Pollination success is influenced by factors such as density and distance from neighbouring conspecifics. However, the pure neighbourhood effects of spatial patterns interaction on pollination remains poorly understood. In this study, we used techniques point pattern analysis (SPPA) to investigate relationship between distribution a specialist pollinator, weevil Derelomus chamaeropis, fruiting its host plant, dwarf palm Chamaerops humilis, within nursery system. We georeferenced population...

Abstract Throughout Europe, increased levels of land abandonment lead to (re)colonization old lands by forests and shrublands. Very little is known about the spatial pattern plants recolonizing such fields. We mapped in two 21–22‐ha plots, located Doñana National Park (Spain), all adult individuals endozoochorous dwarf palm Chamaerops humilis L . determined their sex sizes. used techniques point analysis (SPPA) precisely quantify structure these C. populations. The objective was identify...

Plant–animal mutualisms such as seed dispersal are key interactions for sustaining plant range shifts. It remains elusive whether the organization of with dispersers is reconfigured along expansion landscape template and, if so, its effects accelerate or slow colonization. Here we analyse plant–frugivore in a scenario rapid population Mediterranean juniper. We combined network analyses field surveys, sampling between individual plants and frugivores by DNA-barcoding phototrapping over two...

It has been suggested that there is a geographic dichotomy in the pollination systems of chiropterophilous columnar cacti: intra-tropical areas they are pollinated almost exclusively by bats, whereas extratropical birds and bees. However, currently studies clumped both taxonomically (mainly Pachycereeae species) geographically Tehuacan Valley Sonoran Desert). This clumping limits possibility generalising pattern to other regions or cactus tribes. Only four 36 cacti Pilosocereus have studied....

Nursery pollination is a highly specialized interaction in which pollinators breed inside plant reproductive structures. Pollinator occupancy of host plants often depends on location, flowering synchrony and sex. The nursery system between the dioecious dwarf palm Chamaerops humilis (Arecaceae) host-specific flower weevil Derelomus chamaeropsis was investigated. For first time, sex, spatial distribution related to probability abundance D. larvae, important traits influencing both pollinator...

The nature and the strength of plant–frugivore interactions often vary along an antagonism–mutualism continuum are highly influenced by local ecological context (e.g. level environmental disturbances). However, little is known concerning how setting where take place affects seed dispersal effectiveness (SDE) and, eventually, plant recruitment. This knowledge gap relates to scarcity empirical investigations on individual‐based networks. We assessed whether assembly interaction modes...

Abstract Reproductive isolation is a necessary condition for plant domestication in their centre where crops co‐occur with wild progenitors. However, the identification of reproductive barriers and relative contribution to have been overlooked plants under domestication. We assessed pre‐ post‐pollination between domesticated chaya ( Cnidoscolus aconitifolius ) its centre. found that both exhibit high degree isolation. exhibited some asymmetry: while pre‐pollination (differential pollen...

Abstract Range expansion in plant populations, especially at the colonization front, can be either limited by disproportionately large effects of antagonistic interactions or facilitated their release. How strength changes along successional gradients during range is still poorly documented, when diverse assemblages antagonists (rodents, invertebrates and birds) combine within interaction networks. We study individual‐based, predispersal seed–pulp predator networks a gradient rapidly...

Las creencias, mitos e historias existentes en el ámbito simbólico de los murciélagos tienen una gran influencia la valoración las personas. El objetivo esta investigación es conocer percepción que existe entre ejidatarios Bejucal sobre y servicio ecosistémico dispersión semillas. Esta se realizó dos etapas, primero aplicaron entrevistas semiestructuradas a para sus percepciones posteriormente impartió un taller sensibilización con al final evaluar efectividad nuestras acciones educación...

Ecological restoration requires a holistic view of the interconnectedness between degraded areas, remaining ecosystems, and repercussions land use other socioeconomic costs. In this study, we analyze how biological priorities for change when ecological, social, economic feasibility are considered. A multi‐criteria approach was used to prioritize using Mexican side transboundary Grijalva‐Usumacinta basin (78,831 km 2 ) as study model, one Mexico's most important regions, thanks its hydrology,...

Premise of research. Plant aggregation and pollen origin can profoundly influence pollination success, as measured by fruit initiation development. The effect these variables should be more significant in plants with highly specialized systems, the pool potential pollinators is assumed to smaller than generalized although this possibility has seldom been investigated.Methodology. During two consecutive seasons, we used field observations hand-pollination experiments nursery-pollinated palm...

Reportamos el redescubriento del murciélago cara rayada mayor (Vampyrodes major) en estado de Tabasco, México, después 60 años. Los registros se basan dos individuos capturados con redes niebla dentro área natural protegida Cañón Usumacinta, municipio Tenosique. Éstos confirman su procedencia y representan los más recientes la región sureste México.
