Summary Root, stem and leaf traits are thought to be functionally coordinated maximize the efficiency of acquiring using limited resources. However, evidence is mixed for consistent whole‐plant trait coordination among woody plants, we lack a clear understanding adaptive value root along soil resource gradients. If fine roots below‐ground analogue leaves, then low specific length ( SRL ) high tissue density should common on infertile soil. Here, test prediction that root, relative growth rate respond in unison with fertility We measured individual seedlings 66 tree species grown controlled conditions.

Hypervolume concepts in niche‐ and trait‐based ecology

Hutchinson's n ‐dimensional hypervolume concept for the interpretation of niches as geometric shapes has provided a foundation research across different fields ecology and evolution. There is now an expanding set applications concepts, well growing statistical methods available to operationalize this with data. The been applied environmental, resource, functional trait, morphometric axes scales, i.e. from individuals, species, communities clades. Further, these have variously interpreted niches, ecological or evolutionary strategy spaces, proxies community structure. This paper highlights applications’ shared mathematical framework, surveys uses fields, discusses key limitations assumptions concepts in general, provides critical guide estimation methods, delineates situations where can be useful.

Allocation, morphology, physiology, architecture: the multiple facets of plant above‐ and below‐ground responses to resource stress

New Phytologist, Год журнала: 2018, Номер 219(4), С. 1338 - 1352

Опубликована: Июнь 1, 2018

Plants respond to resource stress by changing multiple aspects of their biomass allocation, morphology, physiology and architecture. To date, we lack an integrated view the relative importance these plastic responses in alleviating consistency/variability among species. We subjected nine species (legumes, forbs graminoids) nitrogen and/or light shortages measured 11 above-ground below-ground trait adjustments critical alleviation stresses (plus several underlying traits). Nine traits out showed that improved plants' potential capacity acquire limiting at a given time. Above ground, plasticity architecture all appeared important improving capture, whereas below allocation were most acquisition. Six substantial heterogeneity plasticity, with little structuration differences within covariation syndromes. Such comprehensive assessment complex nature phenotypic plants factors, comparison plant across species, makes clear case for high (but largely overlooked) diversity plants, need explore rules structuring them.

Intraspecific trait variation in plants: a renewed focus on its role in ecological processes

Annals of Botany, Год журнала: 2021, Номер 127(4), С. 397 - 410

Investigating the causes and consequences of intraspecific trait variation (ITV) in plants is not novel, as it has long been recognized that such shapes biotic abiotic interactions. While evolutionary population biology have extensively investigated ITV, only last 10 years interest ITV surged within community comparative ecology.

Regeneration: an overlooked aspect of trait‐based plant community assembly models

Journal of Ecology, Год журнала: 2016, Номер 104(5), С. 1284 - 1298

Опубликована: Май 24, 2016

Summary Despite the disproportionate influence that propagule production, dispersal, seed‐to‐seedling recruitment and vegetative reproduction can have on plant population community dynamics, progress has been slow in directed collection of regeneration traits to inform assembly outcomes. While seed mass is globally available linked growth reproductive output, there are limits its explanatory ability. In this essay, we call for expanded efforts integrate a more diverse set into models. First, extend an existing framework conceptualize as series transitional processes whose outcomes influenced by abiotic filters, biotic interactions species traits. We then briefly review literature, highlighting filters demonstrated or theorized importance each transition. Finally, place context emerging modelling approaches trait‐based assembly, summarizing key areas needed these efforts. Synthesis . By incorporating influential empirical studies global data bases, begin disentangle regenerative mechanisms underlying enhance rapidly developing models species’ abundances, distributions responses environmental change.

ΔTraitSDMs: species distribution models that account for local adaptation and phenotypic plasticity

New Phytologist, Год журнала: 2019, Номер 222(4), С. 1757 - 1765

Опубликована: Янв. 30, 2019

Improving our understanding of species ranges under rapid climate change requires application knowledge the tolerance and adaptive capacity populations to changing environmental conditions. Here, we describe an emerging modelling approach, ΔTraitSDM, which attempts achieve this by explaining distribution based on phenotypic plasticity local adaptation fitness-related traits measured across large geographical gradients. The collection intraspecific trait data in common gardens spanning broad clines has promoted development these new models - first trees but now rapidly expanding other organisms. We review, explain harmonize main findings from generation that, including variation over scales, are able provide insights into future ranges. Overall, ΔTraitSDM predictions generally deliver a less alarming message than previous climates, indicating that should help, considerable degree, some plant persist change. ΔTraitSDMs offers perspective analyse single multiple traits, with rationale (co)variation consequently fitness can significantly gradients climates.
