1. The Andes are predicted to warm by 3-5 °C this century with the potential to alter the processes regulating carbon (C) cycling in these tropical forest soils. This rapid warming is expected to stimulate soil microbial respiration and ch...
Interactive effects of landscape history and current management on dispersal trait diversity in grassland plant communities [0.03%]
景观历史和当前管理对草地植物群落传播特性多样性相互作用的影响

Oliver Purschke et al.
Plant communities and their ecosystem functions are expected to be more resilient to future habitat fragmentation and deterioration if the species comprising the communities have a wide range of dispersal and persistence strategies. However...
Coexistence and relative abundance in plant communities are determined by feedbacks when the scale of feedback and dispersal is local [0.03%]
当正相互作用范围较小时，植物群落中物种共存与相对丰度的决定因素

1. Negative plant-soil feedback occurs when the presence of an individual of a particular species at a particular site decreases the relative success of individuals of the same species compared to those other species at that site. This effe...
Testing predictions of the Janzen-Connell hypothesis: a meta-analysis of experimental evidence for distance- and density-dependent seed and seedling survival [0.03%]
检验詹森-康奈尔假设的预测：距离和密度依赖的种子和幼苗生存实验证据的元分析
Liza S Comita,Simon A Queenborough,Stephen J Murphy et al.
Liza S Comita et al.
The Janzen-Connell hypothesis proposes that specialist natural enemies, such as herbivores and pathogens, maintain diversity in plant communities by reducing survival rates of conspecific seeds and seedlings located close to reproductive ad...

Understanding the effects of intraspecific genetic diversity on the structure and functioning of ecological communities is a fundamentally important part of evolutionary ecology and may also have conservation relevance in identifying the si...
Effects of mammalian herbivore declines on plant communities: observations and experiments in an African savanna [0.03%]
哺乳动物减少对植物群落的影响：非洲稀树草原的观察和实验结果
Hillary S Young,Douglas J McCauley,Kristofer M Helgen et al.
Hillary S Young et al.
1. Herbivores influence the structure and composition of terrestrial plant communities. However, responses of plant communities to herbivory are variable and depend on environmental conditions, herbivore identity and herbivore abundance. As...
Plants do not count… or do they? New perspectives on the universality of senescence [0.03%]
植物不会计算……还是会有呢？关于衰老普遍性的新观点

1. Senescence, the physiological decline that results in decreasing survival and/or reproduction with age, remains one of the most perplexing topics in biology. Most theories explaining the evolution of senescence (i.e. antagonistic pleiotr...

1. Senescence (an increase in the mortality rate or force of mortality, or a decrease in fertility, with increasing age) is a widespread phenomenon. Theories about the evolution of senescence have long focused on the age trajectories of the...

1.Adams and Zhang recently published one of the best studies so far of patterns of insect folivory along a latitudinal (climatic) gradient. They show clear negative trends in foliage loss in relation to temperature for certain groups of ins...
Spatial variation in disease resistance: from molecules to metapopulations [0.03%]
从分子到元种群的疾病抵抗力的空间变异
Anna-Liisa Laine,Jeremy J Burdon,Peter N Dodds et al.
Anna-Liisa Laine et al.
Variation in disease resistance is a widespread phenomenon in wild plant-pathogen associations. Here, we review current literature on natural plant-pathogen associations to determine how diversity in disease resistance is distributed at dif...
