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

open access: yesJournal 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

Recruitment limitation in three large‐seeded plant species in a tropical moist forest

open access: yesBiotropica, Volume 54, Issue 2, Page 418-430, March 2022., 2022
Recruitment limitation results from three mechanisms: (i) lack of seed sources (i.e., source limitation), (ii) failure of available seeds to reach recruitment sites (i.e., dispersal limitation), and (iii) failure of arrived seeds to establish at a location (i.e., establishment limitation).

Synthesis procedure for, and characteristics of, one-port linear magnetoelastic dispersors

open access: yesElectronics Letters, 1966
The necessity of an internal magnetic field with spatially constant gradient for a linear frequency–time delay property of θ = 0 magnetoelastic waves is demonstrated, and certain limitations on achievable time–bandwidth product are formulated.

Waterbird seed‐dispersal networks are similarly nested but less modular than those of frugivorous birds, and not driven by functional traits

open access: yesFunctional Ecology, Volume 34, Issue 11, Page 2283-2291, November 2020., 2020
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Frugivory is widely recognized as vital for the dispersal of many plants. Moreover, plant species and their frugivorous dispersers form seed‐dispersal assemblages whose structure has important implications for the persistence and stability of the ...

O lambari Astyanax altiparanae (Characidae) pode ser um dispersor de sementes?

open access: yesActa Scientiarum. Biological Sciences, 2003
This work characterized the feeding of Astyanax altiparanae in the sub-basin of Corumbataí river and in the basin of Jacaré-pepira river with a focus on the ingestion of Croton urucurana seeds. The food items of Astyanax altiparanae were, in decreasing APD (Alimentary Preference Degree) order: allochthonous insects, allochthonous plant material, Croton
