Comportamento de vacas mestiças holandês x zebu, em pastagem de Brachiaria decumbens em sistema silvipastoril Behavior of holstein x zebu crossbreed cows grazing Brachiaria decumbens in a silvipastoral system

Ciência e Agrotecnologia, 2005
Estudou-se o comportamento de vacas mestiças Holandês-Zebu, em sistema silvipastoril, avaliando-se o percentual do tempo em que os animais se mantiveram em pé, comendo, ruminando ou em ócio, no verão e no inverno e o tempo em que as vacas se mantiveram ...

No way back: decadal lack of functional recovery of a coralligenous community in a warming Mediterranean

Oikos, EarlyView.
Anthropogenic disturbances are degrading nature at a rate that exceeds its capacity to recover. While considerable research has focused on understanding ecosystem impacts, recovery processes remain comparatively overlooked, particularly in marine ecosystems, where long‐term data on how highly complex systems respond to disturbances are scarce.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

Oikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

Oikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Herniaria alpina (Caryophyllaceae) in the Iberian Peninsula

Anales del Jardín Botánico de Madrid, 2019
Herniaria alpina Chaix is a southern European orophyte distributed in the Alps, Apennines and the Pyrenees. In the Pyrenees it is considered a rare species because it is only known from few locations of the northern side (France) and there are no ...

Trait‐associated pathway links plant diversity to litterfall phenology in a seasonally dry tropical forest

Oikos, EarlyView.
Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...

Reproductive strategies of the most geographically isolated Trachylepis support predictions of the island syndrome

Scientific Reports
The island syndrome hypothesis predicts that insular organisms exhibit phenotypic differences from their mainland counterparts, particularly in reproductive strategies.

Paleoecología del Holoceno en la Gran Sabana, SE Venezuela: Análisis preliminar de polen y microcarbones en la Laguna Encantada

Collectanea Botanica, 2009
La región de la Gran Sabana, al SE de Venezuela, se caracteriza por la presencia de extensas sabanas neotropicales, en un clima cálido y húmedo, que parece más propicio para la existencia de bosques húmedos.
