Recovery and Degradation Drive Changes in the Dispersal Capacity of Stream Macroinvertebrate Communities. [PDF]

Glob Chang Biol
Freshwater 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 Biol
Abstract 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

Murciélagos dispersores de semillas en gradientes sucesionales de la Orinoquia (San Martín, Meta, Colombia).

Acta Biológica Colombiana, 2017
La dispersión de semillas por fauna juega un papel fundamental en la reproducción vegetal. Los murciélagos son unos de los dispersores de semillas más importantes en los ecosistemas neotropicales.

APPLICATION OF A PULSATING DISPERSOR AS A HYDRODYNAMIC CAVITATION REACTOR FOR PREPARATION OF COAL WATER FUEL

Thermophysics and Thermal Power Engineering, 2023
A brief review of modern technologies for the production and use of coal-water fuel (CWF) is carried out. The trend of creating innovative technologies for the production of coal-water suspensions using hydrodynamic cavitation methods was noted. Varieties of rotary-type cavitation reactors, which are used for wet grinding of coal and the creation of ...

Linking animal behaviour and tree recruitment: Caching decisions by a scatter‐hoarder corvid determine seed fate in a Mediterranean agroforestry system

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

Densidad de semillas y plántulas de Zanthoxylum fagara en México y Zanthoxylum coco en Argentina: influencia de plantas bajo las cuales ocurren y borde de la vegetación

Botan‪ical Sciences, 2020
Antecedentes: La distribución de plantas depende de dispersores que transportan semillas a hábitats adecuados y de plantas que faciliten o inhiban germinación y establecimiento. Es importante conocer cómo estos factores influyen en la distribución de la
