Summary Plant hydraulics mediate terrestrial woody plant productivity, influencing global water, carbon, and biogeochemical cycles, as well ecosystem vulnerability to drought climate change. While inter‐specific differences in hydraulic traits are widely documented, intra‐specific variability is less known important for predicting change impacts. Here, I present a conceptual framework this trait variability, reviewing the mechanisms that drive consequences vegetation response performed meta‐analysis on published studies ( n = 33) of variation prominent – water potential at which 50% stem conductivity lost (P50) compared within genera functional types used by dynamic model. found ecologically relevant magnitudes, equivalent c . 33% genus, larger angiosperms than gymnosperms, although limited number highlights more research greatly needed. Furthermore, were poorly situated capture key across species, indicating need approach prediction impacts from trait‐based, rather type‐based perspective.

Summary Schedules of survival, growth and reproduction are key life‐history traits. Data on how these traits vary among species populations fundamental to our understanding the ecological conditions that have shaped plant evolution. Because demographic schedules determine population or decline, such data help us understand different biomes shape ecology, communities respond global change develop successful management tools for endangered invasive species. Matrix models summarize life cycle components reproduction, while explicitly acknowledging heterogeneity classes individuals in population. comparable structures, their emergent measures dynamics, as rate mean expectancy, direct biological interpretations, facilitating comparisons Thousands matrix been parameterized from empirical data, but they largely dispersed through peer‐reviewed grey literature, thus remain inaccessible synthetic analysis.

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

Опубликована: Янв. 27, 2021

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.

Abstract Sustainable strategies for managing weeds are critical to meeting agriculture’s potential feed the world’s population while conserving ecosystems and biodiversity on which we depend. The dominant paradigm of weed management in developed countries is currently founded two principal tools herbicides tillage remove weeds. However, evidence negative environmental impacts from both growing, herbicide resistance increasingly prevalent. These challenges emerge a lack attention how interact with regulated by agroecosystem as whole. Novel technological proposed control, such new herbicides, gene editing, seed destructors, do not address these systemic thus unlikely provide truly sustainable solutions. Combining multiple techniques an Integrated Weed Management strategy step forward, but many integrated still remain overly reliant too few tools. In contrast, advances ecology revealing wealth options manage at level that, rather than aiming eradicate weeds, act regulate populations limit their diversity. Here, review current state knowledge identify this can be translated into practical management. major points following: (1) diversity type crops, actions limiting resources manipulated competitiveness promoting diversity; (2) contrast tools, ecological approaches tend synergistic other functions; (3) there existing practices compatible approach that could systems, alongside explore. Overall, demonstrates integrating systems-level thinking agronomic decision-making offers best route achieving

Within‐species patterns challenge our understanding of the leaf economics spectrum

Ecology Letters, Год журнала: 2018, Номер 21(5), С. 734 - 744

Опубликована: Март 23, 2018

The utility of plant functional traits for predictive ecology relies on our ability to interpret trait variation across multiple taxonomic and ecological scales. Using extensive data sets within species, species communities, we analysed whether at what scales leaf economics spectrum (LES) show predicted trait-trait covariation. We found that most in LES is often, but not universally, high levels (between families or genera a family). However, covariation shows distinct scale dependence, with some correlations showing opposite signs vs. species. responded independently environmental gradients few shared responses conclude that, small scales, plasticity may obscure reverse the broad evolutionary linkages between traits, meaning cannot always be interpreted as differences resource use strategy.

Adjustments and coordination of hydraulic, leaf and stem traits along a water availability gradient

New Phytologist, Год журнала: 2019, Номер 223(2), С. 632 - 646

Опубликована: Янв. 13, 2019

Trait variability in space and time allows plants to adjust changing environmental conditions. However, we know little about how this is distributed coordinated at different organizational levels. For six dominant tree species northeastern Spain (three Fagaceae three Pinaceae) quantified the inter- intraspecific of a set traits along water availability gradient. We measured leaf mass per area (LMA), nitrogen (N) concentration, carbon isotope composition leaves (δ13 C), stem wood density, Huber value (Hv, ratio cross-sectional sapwood area), sapwood-specific leaf-specific hydraulic conductivity, vulnerability xylem embolism (P50 ) turgor loss point (Ptlp ). Differences between families explained largest amount for most traits, although was also relevant. Species occupying wetter sites showed higher N, P50 Ptlp , lower LMA, δ13 C Hv. when trait relationships with were assessed within they held only Hv . Overall, our results indicate that adjustments gradient relied primarily on changes resource allocation relations.

Will among‐population variation in seed traits improve the chance of species persistence under climate change?

Global Ecology and Biogeography, Год журнала: 2014, Номер 24(1), С. 12 - 24

Опубликована: Окт. 10, 2014

Abstract Aim Seed traits related to recruitment have direct relevance for plant fitness and persistence. Trait variation in time among populations may increase species resilience ultimately reduce the risk of extinction. However, patterns among‐population critical remain poorly known are often disregarded when considering extinction under future climates. Location Global. Methods In this paper we review synthesize current knowledge about physiological morphological recruitment. We outline consequences that persistence climate change, discuss implications conservation, management restoration. Results The evaluated studies provide compelling evidence underpinning seedling emergence, growth establishment is widespread. Contrary expectations, environmental gradients do not appear be reliable predictors responses individualistic. Likewise, well‐established cross‐species consistently reflected within a species. As pattern unpredictable, cannot make simple generalizations how allocated across geographic ranges or extent versus fixed genetic differences. Nor these clearly elucidate potential mitigate negative effects change. Main conclusions If ignore seed traits, assume it will follow clines, so at our own peril. such an approach likely include biased forecasts range dynamics, hindering identification material most appropriate restoration management. Further research integrates ecology emerging evolutionary techniques identify distribution foundation mechanisms driving them urgently required guide maintenance systems face rapidly changing
