The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Frugivoria e dispersão de sementes pelo lagarto teiú Tupinambis merianae (Reptilia: Teiidae) Frugivory and seed dispersal by the tegu lizard Tupinambis merianae Reptilia: Teiidae

open access: yesPapéis Avulsos de Zoologia, 2004
Os lagartos teiús possuem uma dieta generalista, podendo agir como importantes dispersores de sementes em florestas semidecíduas do sudeste do Brasil. Foram estudadas a frugivoria e a dispersão de sementes de lagartos teiús usando animais em cativeiro ...

Preliminary investigation of flexibility in learning color-reward associations in gibbons (Hylobatidae) [PDF]

open access: yes, 2015
Previous studies in learning set formation have shown that most animal species can learn to learn with subsequent novel presentations being solved in fewer presentations than when they first encounter a task.

Stratified sampling enhances the understanding of bat–fruit networks in the southern Atlantic Forest

open access: yesOikos, EarlyView.
Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

Scat piling and strong frugivory of the Balearic lizard, Podarcis lilfordi (Günther, 1874)

open access: yesBMC Zoology, 2022
Background In lacertid lizards from Mediterranean islands, frugivory is common, particularly under prey scarcity, a characteristic of small islands. In several populations, the diet of the Balearic lizard, Podarcis lilfordi, is extremely variable and ...

Sugar composition of wild fruits in Hong Kong, China [PDF]

open access: yes, 1998
Soluble carbohydrates are the major nutritional reward in the pulp of most vertebrate dispersed fruits (Corlett 1996, Herrera 1987, Johnson et al. 1985, Jordano 1995). However, although detailed analyses have been made of the carbohydrate content of many

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

open access: yesOikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

open access: yesOikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Frugivoria por aves em Eugenia uniflora L. (Myrtaceae) em ambientes antropizados na região de Sorocaba–SP. Frugivory by birds in Eugenia uniflora L. (Myrtaceae) at anthropic environment in Sorocaba–SP region [PDF]

open access: yesRevista do Instituto Florestal, 2012
As aves, assim como toda fauna consumidora de frutos possuem grande importância no processo de dispersão de sementes. O declínio de suas populações pode gerar consequências para a reprodução e para o crescimento populacional dessas plantas zoocóricas, se
