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

Ecosphere, 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]

Acta 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.

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

Acta 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.

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

Acta 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

Guangxi 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

Dispersal estimates of plant species on Marion Island

, 2022
This is dataset on records of dispersal estimates of plant species found on sub-Antarctic Marion Island. Four different dispersal syndromes have been considered: anemochory, zoochory, anthropogenic activity and thalassochory. The file also includes trait

Espectro e distribuição vertical das estratégias de dispersão de diásporos do componente arbóreo em uma floresta estacional no sul do Brasil Spectrum and vertical distribution of diaspore dispersal modes in a seasonal forest in Southern Brazil

Acta Botânica Brasílica, 2007
A dispersão de diásporos é um evento de elevada importância para as espécies vegetais, que dispõem de diversas estratégias para este fim. O presente estudo teve por objetivos conhecer e caracterizar o espectro das diferentes estratégias de dispersão do ...

Effects of climatic and social factors on dispersal strategies of alien species across China

, 2020
Determination of dispersal strategies of alien species and its relationship with social and climatic factors are essential to understand the mechanisms of species invasion and adaption. Based on morphological trait, dispersal mode, and dispersal agent of

Chuva de sementes de espécies lenhosas florestais em mosaicos de floresta com Araucária e campos no Sul do Brasil Seed rain of woody species in mosaics of Araucaria forest and grasslands in Southern Brazil

Acta Botânica Brasílica, 2011
Mecanismos de dispersão de diásporos e recrutamento de plântulas evitam a competição intra-específica e possibilitam a colonização de novos ambientes. Em áreas de transição entre florestas e vegetação campestre esses processos não são aleatórios, e sim ...

Squills vs. Hyacinths – A revised genus delimitation in Hyacinthinae (Hyacintheae, Scilloideae, Asparagaceae) based on phylogenomics

TAXON, Volume 75, Issue 5, October 2026.
Abstract Scilla s.l. (Asparagaceae: Scilloideae) represents a notable Mediterranean geophyte radiation, yet genus delimitation in subtribe Hyacinthinae has long suffered from inconsistent and conflicting generic concepts. A limited set of informative morphological characters and recurrent shifts in circumscription have repeatedly hindered progress ...
