Tropical grasses fuel the majority of fires on Earth. In fire-prone landscapes, enhanced flammability may be adaptive for grasses via the maintenance of an open canopy and an increase in spatiotemporal opportunities for recruitment and rege...
Early positive effects of tree species richness on herbivory in a large-scale forest biodiversity experiment influence tree growth [0.03%]
大型森林生物多样性实验早期的树种丰富度对食草动物的作用影响树木生长

Despite the importance of herbivory for the structure and functioning of species-rich forests, little is known about how herbivory is affected by tree species richness, and more specifically by random vs. non-random species loss. We assesse...
Longitudinal analysis in Plantago: strength of selection and reverse-age analysis reveal age-indeterminate senescence [0.03%]
纵向分析表明千里光属植物衰老是年龄无关的且存在强自然选择作用

1. Senescence is usually viewed as increased age-specific mortality or decreased age-specific fecundity due to the declining ability of natural selection to remove deleterious age-specific mutations with age. In herbaceous perennial plants,...
Long-term disturbance dynamics and resilience of tropical peat swamp forests [0.03%]

1. The coastal peat swamp forests of Sarawak, Malaysian Borneo, are undergoing rapid conversion, predominantly into oil palm plantations. This wetland ecosystem is assumed to have experienced insignificant disturbance in the past, persistin...
Soil nutrient heterogeneity modulates ecosystem responses to changes in the identity and richness of plant functional groups [0.03%]

Recent research has shown that biodiversity may has its greatest impact on ecosystem functioning in heterogeneous environments. However, the role of soil heterogeneity as a modulator of ecosystem responses to changes in biodiversity remains...

Recent evidence suggests that soil nutrient heterogeneity, a ubiquitous feature of terrestrial ecosystems, modulates plant responses to ongoing global change (GC). However, we know little about the overall trends of such responses, the GC d...
Tree diversity and the role of non-host neighbour tree species in reducing fungal pathogen infestation [0.03%]
树木多样性和非寄主邻近树种在减少真菌病原体危害方面的作用

Lydia Hantsch et al.
The degree to which plant pathogen infestation occurs in a host plant is expected to be strongly influenced by the level of species diversity among neighbouring host and non-host plant species. Since pathogen infestation can negatively affe...
Conditions favouring hard seededness as a dispersal and predator escape strategy [0.03%]
利于硬实作为一种传播和逃逸策略的条件

Torbjørn R Paulsen et al.
The water-impermeable seed coat of 'hard' seeds is commonly considered a dormancy trait. Seed smell is, however, strongly correlated with seed water content, and hard seeds are therefore olfactionally cryptic to foraging rodents. This is th...
Evidence for shifts to faster growth strategies in the new ranges of invasive alien plants [0.03%]

Understanding the processes underlying the transition from introduction to naturalization and spread is an important goal of invasion ecology. Release from pests and pathogens in association with capacity for rapid growth is thought to conf...

There is increasing world-wide concern about the impact of the introduction of exotic species on ecological communities. Since many exotic plants depend on native pollinators to successfully establish, it is of paramount importance that we ...
