Effect of population reinforcement method, site, and plant characteristics on early establishment of the rare endemic plant species Minuartia smejkalii

Nordic Journal of Botany, EarlyView.
Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Seed predation by rodents and safe sites for large-seeded trees in a fragment of the Brazilian Atlantic forest

Brazilian Journal of Biology
Seed predation by small rodents is an emerging theme in the ecology of modified landscapes. Here we investigate the role played by the small rodent Oryzomys oniscus as a seed predator of large-seeded trees in a large remnant of the Atlantic forest - the ...

Past and present disturbances generate spatial variation in seed predation

Ecosphere, 2020
Seed survival is a key process for plant populations; variation in the activity and abundance of animals that consume seeds can lead to dramatic shifts in seed fate.

Distribution under climate change of Anemone coronaria: linking flower colour and seed dispersal

Nordic Journal of Botany, EarlyView.
Flower colour polymorphism is driven by divergent selection regimes on the colour morphs across time and space. Anemone coronaria, a colour‐polymorphic geophyte with red, purple, and white flowers, displays a geographic pattern along Israel's aridity gradient: polymorphic populations are restricted to Mediterranean climates, while monomorphic‐red ...

Beyond predator satiation: Masting but also the effects of rainfall stochasticity on weevils drive acorn predation

Ecosphere, 2017
Escaping seed predation is a classic “economy of scale” hypotheses (predator satiation hypothesis, Psh) to explain the selection for the synchronous production of massive and nil seed crops (masting) in plants.

Modelo de la dinámica poblacional de Anoda cristata en un cultivo de soja resistente a glifosato bajo diferentes sistemas de manejo [PDF]

, 2007
Se desarrolló un modelo de simulación de la dinámica del banco de semillas de Anoda cristata (L.) Schlecht en un cultivo de soja. El modelo considera distintas estrategias de manejo: ausencia de control, control con la dosis recomendada y con la mitad de

The fluctuating resource hypothesis explains invasibility, but not exotic advantage following disturbance [PDF]

, 2018
Invasibility is a key indicator of community susceptibility to changes in structure and function. The fluctuating resource hypothesis (FRH) postulates that invasibility is an emergent community property, a manifestation of multiple processes that cannot ...

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

Oikos, 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.
