| 1 | Towards a trait-based quantification of species niche显示文摘Aims Although the niche concept is of prime importance in ecology,the quantification of plant species’niches remains difficult.Here we propose that plant functional traits,as determinants of species performance,may be useful tools for quantifying species niche parameters over environmental gradients.Important findings Under this framework,the mean trait values of a species determine its niche position along gradients,and intraspecific trait variability determines its niche breadth.This trait-based approach can provide an operational assessment of niche for a potentially large number of species,making it possible to understand and predict species niche shifts under environmental changes.We further advocate a promising method that recently appeared in the literature,which partitions trait diversity into among-and within-community components as a way to quantify the species niche in units of traits instead of environmental parameters.This approach allows the switch of the focus from ecological niches to trait niches,facilitating the examination of species coexistence along undefined environmental gradients.Altogether,the trait-based approach provides a promising toolkit for quantifying the species ecological niche and for understanding the evolution of species niche and traits. | Cyrille Violle Lin Jiang | 2009 | Journal of Plant Ecology2009，2，2： | 9 |
| 2 | Early dynamics in plant community trait responses to a novel, more extreme hydrological gradient显示文摘Aims For temperate regions such as Northern Europe,predicted climate change patterns include an increase in winter precipitation causing increased risk of flooding,whereas periods of droughts will become more frequent in summer.The aim of this study is to explore vari-ations in plant functional trait distributions along a hydrological gradient spanning from recurrent drought events to recurrent flood-ing-mimicking future precipitation patterns.Methods The experiment was conducted in a controlled grassland experi-ment over a period of 3 years.A novel and more extreme hydro-logical regime was achieved by manipulating the flow of a nearby stream thereby creating a continuous hydrological gradient from flooding during winter to drought during summer.Plant commu-nity responses were recorded along this hydrological gradient.Community-weighted trait distribution changes along the gradient were described using null models.Six functional traits were con-sidered:seed mass,leaf dry matter content(LDMC),leaf area,leaf thickness,specific leaf area(SLA)and height.Important findings Over time,responses in plant functional traits changed at the community level.Over the study period consistent changes occurred in the mean trait value of several traits.Communities in relatively dry plots became dominated by species with water-conserving life strategies,represented by high seed mass and thick leaves.In contrast,disturbance-resistant species(high leaf dry matter content)became dominant in flooded plots,indicating that persistence to flooding was the most important factor control-ling the functional structure in those communities.Furthermore,a high abundance of small-seeded species in flooded plots likely indicates higher frequency of species with higher dispersal ability through hydrochory.In conclusion,plant traits are useful for predicting responses to climate change,but abrupt and extreme climate event may cause unexpected responses because they have no analog to previously more stable conditions.We suggest that traits related to dispersal and resistance to disturbance are useful in describing responses to flooding and that these traits should be included in future inves-tigations of plant community responses to extreme hydrological events. | Andrea Oddershede Cyrille Violle Annette Baattrup-Pedersen Jens-Christian Svenning Christian Damgaard | 2019 | Journal of Plant Ecology2019，12，2： | 2 |
