Fuzzy relationships among plant dispersal mechanisms, syndromes, and animal vectors. [PDF]

Ecology
Abstract Knowledge of which animal clades and dispersal mechanisms contribute to seed dispersal is critical for understanding the ecology and evolution of plant communities. However, a broad understanding is limited by a focus on single clades and mechanisms. Here, we analyzed a Europe‐wide multi‐clade seed dispersal dataset with interactions among 447

Neglected seed dispersers and research compartmentalisation: how much do we know about what we don't know? [PDF]

New Phytol
Geographic distribution of seed dispersal studies by disperser guild. Summary Seed dispersal is critical for long‐term ecosystem resilience. However, excessive compartmentalisation of research into particular disperser guilds (e.g. birds) hampers our understanding of their relative contributions to overall seed dispersal, risking erroneous conclusions ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities. [PDF]

J Anim Ecol
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Community Assembly Mechanism of Woody Plants at Different Successional Stages in Karst Areas Based on Functional Traits and Phylogeny. [PDF]

Ecol Evol
This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...

Is the spread of the alien water boatman Trichocorixa verticalis verticalis (Hemiptera, Corixidae) aided by zoochory and drought resistant eggs? [PDF]

Freshwater Biology, 2020
Abstract Desiccation resistance is a key trait determining the distribution of aquatic insects, their potential for overland dispersal, and survival during drought periods in temporary waterbodies, as well as the spread of invasive species. Passive dispersal by waterbirds is considered to be a key process favouring the spread of invasive species and ...

Differences in plant-dispersal mechanisms between contrasting Brazilian savanna habitats

, 2022
By favouring long-distance dispersal, anemochory is often associated with open and patchy habitats, whereas zoochory enables short-distance dispersal and prevails in closed and extensive habitats.

Fruiting phenology and dispersal syndromes in a sandy coastal plain in southeastern Brazil [PDF]

Rodriguésia, 2022
Fruits have a wide variety of morphological and phenological characteristics that have been related to environmental conditions and seed dispersal mode. In this paper, we describe the fruit morphology, the fruiting phenology and infer dispersal patterns ...

Vegetative and reproductive tree phenology of ecological groups in a tropical dry forest in central Veracruz, Mexico

Botan‪ical Sciences, 2016
Background Tree phenology has been related to abiotic and biotic factors that trigger and regulate phenological patterns. Question We investigated whether tree species classified into ecological groups of species of successional status (late-, early ...

Bird-plant interaction networks in native forests and eucalyptus plantations within a protected area

Papéis Avulsos de Zoologia, 2021
Frugivory is a plant-animal mutualistic interaction carried out mostly by birds. It consists in the bird consumption of fruits with later dispersion of the plants’ seeds, helping in the vegetation regeneration.

Síndromes de dispersão de diásporos das espécies de trechos de vegetação ciliar do rio das Pacas, Querência - MT Syndromes of diaspores dispersal of species of riparian vegetation of the river from Pacas, Querência - MT

Acta Amazonica, 2010
As adaptações das plantas, conforme seus agentes dispersores, correlacionam-se com as características morfológicas de cada espécie e família e com a região em que esta predomina, sendo que as sementes evoluíram de acordo com os dispersores.
