Dispersal of bacteria and stimulation of permafrost decomposition by Collembola [PDF]
Contrary to most soils, permafrost soils have the atypical feature of being almost entirely deprived of soil fauna. Abiotic constraints on the fate of permafrost carbon after thawing are increasingly understood, but biotic constraints remain scarcely ...

Driver's Seat: Understanding Divergent Zoochorous Dispersal of Propagules [PDF]
The functional role, relative importance, and the spatial and temporal parameters of different vector species, which underpin the passive dispersal (zoochory) of organisms (or their propagules), are frequently poorly understood. Accordingly, a conceptual

Joint evolution of mutualistic interactions, pollination, seed dispersal mutualism, and mycorrhizal symbiosis in trees [PDF]
世界各地、1万種の解析から見えてきた樹木の進化パターン--送粉共生、種子散布共生、菌根共生の相関進化--京都大学プレスリリース. 2024-05-13.● Mycorrhizal symbiosis, seed dispersal, and pollination are recognized as the most prominent mutualistic interactions in terrestrial ecosystems.

The mutualism-antagonism continuum in Neotropical palm-frugivore interactions: from interaction outcomes to ecosystem dynamics. [PDF]
ABSTRACT Frugivory, that is feeding on fruits, pulp or seeds by animals, is usually considered a mutualism when interactions involve seed dispersal, and an antagonism when it results in the predation and destruction of seeds. Nevertheless, most frugivory interactions involve both benefits and disadvantages for plants, and the net interaction outcomes ...

Migratory Songbirds as Potential Ectozoochorous Protist Dispersal Vectors. [PDF]
Protist biogeography, speciation, and systematics continue to generate debate and inquiry because protist distributions and dispersal remain poorly resolved.

Evidence of endozoochory in upland geese Chloephaga picta and white-bellied seedsnipes Attagis malouinus in sub-Antarctic Chile. [PDF]
Birds are known to act as potential vectors for the exogenous dispersal of bryophyte diaspores. Given the totipotency of vegetative tissue of many bryophytes, birds could also contribute to endozoochorous bryophyte dispersal. We evaluated the role of endozoochory in two herbivorous and sympatric bird species in sub‐Antarctic Chile and hypothesized that

Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms. [PDF]
Woodpeckers are ideal candidates for bird‐mediated dispersal for a diverse set of organisms, especially epiphytes. We report high loads of diverse biological propagules extracted from feathers and feet of woodpecker specimens from natural history collections. The study highlights the potential of birds as dispersal vectors of lichens, fungi, bryophytes,

Patterns of Functional Diversity, Species Diversity, and Endemicity Driven by Elevation and Topographic Complexity in a Mediterranean Mountain Refuge. [PDF]
Within the scope of our study, we modeled and mapped the relationships between functional diversity (Rao's Q), alpha species diversity, and endemism with topographic and climatic factors in a mountainous refugial area encompassing all Mediterranean vegetation strata.

Seed dispersal by the cosmopolitan house sparrow widens the spectrum of unexpected endozoochory by granivore birds. [PDF]
This study provides information that may contribute to unravel the actual role of the cosmopolitan house sparrow as disperser of a likely broad spectrum of wild, cultivated and exotic plants, an unexplored aspect that open up eco‐evolutionary and applied questions.

Evolution of Seed Dispersal Modes in the Orchidaceae: Has the Vanilla Mystery Been Solved?
Orchid seeds are predominantly wind-dispersed, often developed within dry, dehiscent fruits that typically release millions of dust-like seeds into the air.
