Abstract Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, influence ecosystem properties their benefits detriments people. trait data thus represent the basis for a vast area research spanning from evolutionary biology, community functional ecology, biodiversity conservation, landscape management, restoration, biogeography earth system modelling. Since its foundation in 2007, TRY database plant traits has grown continuously. It now provides unprecedented coverage under an open access policy is main used by worldwide. Increasingly, also supports new frontiers trait‐based research, including identification gaps subsequent mobilization or measurement data. To support this development, article we evaluate extent compiled analyse emerging patterns representativeness. Best species achieved categorical traits—almost complete ‘plant growth form’. However, most relevant ecology vegetation modelling are characterized continuous intraspecific variation trait–environmental relationships. These have be measured on individual respective environment. Despite coverage, observe humbling lack completeness representativeness these many aspects. We, therefore, conclude that reducing biases remains key challenge requires coordinated approach measurements. This can only collaboration with initiatives.

The total dispersal kernel: a review and future directions

AoB Plants, Год журнала: 2019, Номер 11(5)

Abstract The distribution and abundance of plants across the world depends in part on their ability to move, which is commonly characterized by a dispersal kernel. For seeds, total kernel (TDK) describes combined influence all primary, secondary higher-order vectors overall for plant individual, population, species or community. Understanding role each vector within TDK, critically important being able predict responses changing biotic abiotic environment. In addition, fully characterizing TDK including may affect predictions population spread. Here, we review existing research discuss advances empirical, conceptual modelling statistical approaches that will facilitate broader application. concept simple, but few examples well-characterized TDKs exist. We find significant empirical challenges exist, as many studies do not account (e.g. gravity, vectors), inadequately measure estimate long-distance resulting from multiple and/or neglect spatial heterogeneity context dependence. Existing mathematical methods allow fitting individual kernels combining them form TDK; these perform best if robust prior information available. recommend cycle parameterize TDKs, where data inform models, turn additional collection.

Humans take control of fire-driven diversity changes in Mediterranean Iberia’s vegetation during the mid–late Holocene

The Holocene, Год журнала: 2019, Номер 29(5), С. 886 - 901

Опубликована: Фев. 14, 2019

Fire regime changes are considered a major threat to future biodiversity in the Mediterranean Basin. Such predictions remain uncertain, given that fire and their ecological impacts occur over timescales too long for direct observation. Here we analyse centennial- millennial-scale shifts regimes compositional turnover track consequences of on vegetation diversity. We estimated rate-of-change, richness (beta diversity) 13 selected high-resolution palaeoecological records from Iberia compared these with charcoal-inferred changes. Event sequence analysis showed be significantly temporally associated turnover, particularly during last three millennia. find timing direction diversity change best explained by long-term human–environment interactions dating back perhaps 7500 years.

Understanding and modelling wildfire regimes: an ecological perspective

Опубликована: Ноя. 16, 2021

Abstract Recent extreme wildfire seasons in several regions have been associated with exceptionally hot, dry conditions, made more probable by climate change. Much research has focused on fire weather and its drivers, but natural regimes—and their interactions human activities—are far from being comprehensively understood. There is a lack of clarity about the ‘causes’ wildfire, how ecosystems could be managed for co-existence people. We present evidence supporting an ecosystem-centred framework improved understanding modelling wildfire. Wildfire long geological history pervasive process contemporary plant communities. In some biomes, would frequent without settlement; others they unchanged or less frequent. A world greater forest cover, especially present-day savannas. Many species missing, because regimes co-evolved traits that resist, adapt to promote Certain are favoured different frequencies, may missing normally fire-free. For example, post-fire resprouting common among woody plants high-frequency than where infrequent. The impact habitat fragmentation crucially depends whether ecosystem fire-adapted. fire-free ecosystems, facilitates starts detrimental biodiversity. fire-adapted inhibits fires spreading suppression This interpretation explains observed, counterintuitive patterns spatial correlation between potential ignition sources.

Leaf water content contributes to global leaf trait relationships

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Сен. 21, 2022

Abstract Leaf functional traits are important indicators of plant growth and ecosystem dynamics. Despite a wealth knowledge about leaf trait relationships, mechanistic understanding how biotic abiotic factors quantitatively influence variation scaling is still incomplete. We propose that water content (LWC) inherently affects other traits, although its role has been largely neglected. Here, we present modification previously validated model based on metabolic theory use an extensive global dataset to test it. Analyses show mass-based photosynthetic capacity specific area increase nonlinearly with LWC, as predicted by the model. When effects temperature LWC controlled, numerical values for area-mass exponents converge onto 1.0 across groups, types, latitudinal zones. The data also indicate mass better predictor whole-leaf photosynthesis than nitrogen phosphorus masses. Our findings highlight comprehensive can predict some patterns from economics spectrum.
