Effects of past pollution on zoochory in a recovering mixed temperate—boreal forest

open access: yesÉcoscience, 2012
In landscapes perturbed by industrial mining, seed dispersal limitations could affect the potential for forest recovery. We measured seed removal in different vegetation layers by different dispersal vectors to examine the potential for natural recovery of a severely stressed forest in Greater Sudbury, Canada.

Massive and effective acorn dispersal into agroforestry systems by an overlooked vector, the Eurasian magpie (Pica pica)

open access: yesEcosphere, 2019
Oak regeneration and the expansion of forested sites in Eurasia rely on acorn dispersal by animals, especially the Eurasian jay (Garrulus glandarius). However, in open agroforestry systems where jays are absent, such as old fields far from acorn sources,

Experimental approach on the contribution of wind and animal vectors in the dispersal and colonization of testate amoebae (Protista, Amoebozoa) in freshwater ecosystems [PDF]

open access: yesActa Limnologica Brasiliensia
: Aim We aimed to understand how testaceous amoebae spread in new sites, assessing their dispersal potential by wind and animals in freshwater ecosystems. Methods We conducted a field experiment over 33 days between July and August 2018.

Functional turnover and community assemblage during tropical forest succession [PDF]

open access: yes, 2016
Changes in species composition during the succession of ecological communities potentially reflect the differential effects of environmental filters and limiting similarity on structuring communities.

Effects of gut passage on the germination of seeds ingested by didelphid marsupials in a neotropical savanna

open access: yesActa Botânica Brasílica, 2013
We analyzed the effects that passage through the guts of seven didelphid species had on the seed germination of 10 plant species. This study was conducted in an area of riparian woodland in a cerrado (savanna) reserve in southeastern Brazil.

Alien versus native weeds present in crops of Oranie (North West Algeria): A comparative study of their life-history traits [PDF]

open access: yes, 2012
Algeria is the North African country with the largest number of alien weed species. The analy- sis of Oranie's weed flora showed 29 species of alien species which represents 1.62% from the 1,780 species of the whole spontaneous flora of the oranian ...

Litter production and seed rain in semideciduous forest fragments at different successional stages in the western part of the state of Paraná, Brazil

open access: yesActa Botânica Brasílica, 2014
We documented litter production and seed rain in fragments of semideciduous forest (SDF) in the western part of the state of Paraná, Brazil: a late successional fragment (LF); an early successional fragment (EF); and a reforested late successional ...

Basic characteristics and influencing factors of seed rain of woody plant in fragmented habitats in the Thousand Island Lake

open access: yesGuangxi Zhiwu, 2023
Seed rain can affect species composition, forest community diversity, and plant population and community renewal. Studying the characteristics of seed rain is of great significance for in-depth research on regeneration strategies and restoration of plant
