Individual variance in the attributes of Clusia salvinii Donn. Smith associated with the attraction of frugivores in the dispersal of fruits and seeds [PDF]
Revista Chapingo: Serie Ciencias Forestales y del Ambiente, 2015 La dispersión de semillas es uno de los procesos de las interacciones planta-frugívoro que involucra características propias de la planta con efecto en la atracción de los frugívoros. En este trabajo se estudió la variación individual en los atributos de

Recovery and Degradation Drive Changes in the Dispersal Capacity of Stream Macroinvertebrate Communities. [PDF]
Glob Chang BiolFreshwater ecosystems across Europe are recovering unevenly despite restoration efforts, partly due to the limited ability of many species to disperse. Using a dataset of over 1300 time series, we found that improved ecological quality often leads to gains in macroinvertebrate species with strong dispersal capacities, while degrading sites lose these ...

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife. [PDF]
Conserv BiolAbstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to

Journal of Ecology, Volume 111, Issue 2, Page 400-411, February 2023., 2023 The consequences of seed caching for seedling early establishment are driven by a fine decision‐making process of the disperser. Magpies seemed to ponder the characteristics of the habitat and the seed itself to determine where and how to cache each nut. By doing so, magpies reinforced the quality of seed dispersal effectiveness, as they cached walnuts

Recruitment limitation in three large‐seeded plant species in a tropical moist forest
Biotropica, Volume 54, Issue 2, Page 418-430, March 2022., 2022 Recruitment limitation results from three mechanisms: (i) lack of seed sources (i.e., source limitation), (ii) failure of available seeds to reach recruitment sites (i.e., dispersal limitation), and (iii) failure of arrived seeds to establish at a location (i.e., establishment limitation).
