Seasonal variation of leaf functional traits in sub‐Arctic plants

Oikos, EarlyView.
Leaf functional traits are informative of plant fitness and functions in ecosystems. These functional traits and their variation across geographic extents are much studied but less is known about their temporal variation over a growing season. Here, we provide an analysis of the seasonal variation in six leaf functional traits of 11 sub‐Arctic vascular

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

Quantitative synthesis of the effects of drought on community composition and species interactions in terrestrial ecosystems

Oikos, EarlyView.
Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.

Urban‐driven homogenization of aquatic subsidy size structure cascades to riparian predator communities

Oikos, EarlyView.
The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

Phenological and morphological variations of Oryza rufipogon and O. nivara in Sri Lanka and their evolutionary implications

Scientific Reports
Phenological and morphological variation are widely viewed as a pivotal driver of ecological adaptation and speciation. Here, we investigate variation patterns of flowering phenology and morphological traits within and between O. rufipogon and O.

Assessment of the potential impacts of plant traits across environments by combining global sensitivity analysis and dynamic modeling in wheat

, 2015
A crop can be viewed as a complex system with outputs (e.g. yield) that are affected by inputs of genetic, physiology, pedo-climatic and management information.

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

People and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...
