A research agenda for seed‐trait functional ecology

New Phytologist, Journal Year: 2018, Volume and Issue: 221(4), P. 1764 - 1775

Summary Trait‐based approaches have improved our understanding of plant evolution, community assembly and ecosystem functioning. A major challenge for the upcoming decades is to understand functions evolution early life‐history traits, across levels organization ecological strategies. Although a variety seed traits are critical dispersal, persistence, germination timing seedling establishment, only mass has been considered systematically. Here we suggest broadening range morphological, physiological biochemical add new on niches, population dynamics assembly. The diversity provides an important that will require international collaboration in three areas research. First, present conceptual framework spectrum builds upon current niches. We then lay foundation seed‐trait functional network, establishment which underpin facilitate trait‐based inferences. Finally, anticipate novel insights challenges associated with incorporating diverse into predictive evolutionary ecology, ecology applied ecology.

Seed germination traits can contribute better to plant community ecology

Journal of Vegetation Science, Journal Year: 2016, Volume and Issue: 27(3), P. 637 - 645

Published: Jan. 4, 2016

Abstract Analyses of functional traits have become fundamental tools for understanding patterns and processes in plant community ecology. In this context, regenerative seed play an important, yet overlooked, role because they largely determine the ability plants to disperse re‐establish. A survey recent publications ecology suggests that germination particular are neglected at expense other relevant but overused based only on morphology. As a response bias, we discuss significance comparison with morphological biophysical traits, advocate their use vegetation science. We also demonstrate how research assembly, climate change restoration can benefit from inclusion encompassing functions cannot be explained solely by adult traits. Seed experiments conducted laboratory or field quantify these provide ecologically meaningful relatively easy‐to‐obtain information about properties communities. argue bridging gap between physiologists ecologists will improve prediction assemblages, propose further perspectives including into agenda ecologists.

Using naturally occurring climate resilient corals to construct bleaching-resistant nurseries

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(21), P. 10586 - 10591

Ecological restoration of forests, meadows, reefs, or other foundational ecosystems during climate change depends on the discovery and use individuals able to withstand future conditions. For coral climate-tolerant corals might not remain tolerant in different environments because widespread environmental adjustment physiology symbionts. Here, we test if parent retain their heat tolerance nursery settings, simple proxies predict successful colonies, heat-tolerant suffer lower growth survival normal settings. Before 2015 natural bleaching event American Samoa, set out 800 fragments from 80 colonies four species selected by prior tests have a range intraspecific tolerance. After event, stock parents showed two three times less across than parents. They also retained higher individual genetic diversity through did corals. The best for thermal were response experimental stress, location reef, microclimate. Molecular biomarkers predictive but highly specific. Colony genotype symbiont genus played similarly strong role predicting bleaching. Combined, our results show that selecting host resilience produced multispecies withstood multiple events, can work be inexpensive, clones within reacted very differently

Seeds of future past: climate change and the thermal memory of plant reproductive traits

Consequences of intraspecific variation in seed dispersal for plant demography, communities, evolution and global change

AoB Plants, Journal Year: 2019, Volume and Issue: 11(4)

Published: March 13, 2019

Abstract As the single opportunity for plants to move, seed dispersal has an important impact on plant fitness, species distributions and patterns of biodiversity. However, models that predict dynamics such as risk extinction, range shifts biodiversity loss tend rely mean value parameters rarely incorporate realistic mechanisms. By focusing population value, variation among individuals or variability caused by complex spatial temporal is ignored. This calls increased efforts understand individual in integrate it more explicitly into community involving dispersal. sources, magnitude outcomes intraspecific are poorly characterized, limiting our understanding role mediating communities their response global change. In this manuscript, we synthesize recent research examines sources emphasize its implications populations communities. We argue does not simply add noise systems, but, fact, alters processes with consequences demography, communities, evolution anthropogenic changes. conclude recommendations moving field forward.

Seed germination strategies: an evolutionary trajectory independent of vegetative functional traits

Frontiers in Plant Science, Journal Year: 2015, Volume and Issue: 6

Seed germination strategies vary dramatically among species but relatively little is known about how traits correlate with other elements of plant strategy systems. Understanding drivers critical to our understanding the evolutionary biology reproduction.We present a novel assessment seed focussing on Australian alpine as case study. We describe distribution and ask whether these are correlated with, or form an independent axis to, functional traits.

The ‘Hutchinsonian niche’ as an assemblage of demographic niches: implications for species geographic ranges

Ecography, Journal Year: 2017, Volume and Issue: 41(7), P. 1103 - 1113

Published: Sept. 21, 2017

Hutchinson defined the ecological niche as a hypervolume shaped by environmental conditions under which species can ‘exist indefinitely’. Although several authors further discussed need to adopt demographic perspective of theory, very few have investigated requirements different components species’ life cycles (i.e. vital rates) in order examine their internal structures. It therefore remains unclear how demography, niches and distributions are interrelated. Using comprehensive data for two well‐studied, short‐lived plants ( Plantago coronopus , Clarkia xantiana ), we show that arrangement reveals key features geographic distributions. In opposing trends some individual rates, through responses gradients (demographic compensation), stabilize population growth across range. lack compensation underlies gradient growth, could translate directional range shift. Overall, our results highlight occurrence performance cannot be assumed same, studying relationship is essential better understanding niches. Finally, argue value considering assemblage when systems, predicting dynamics geographical ranges.

Intraspecific variation in lizard heat tolerance alters estimates of climate impact

Journal of Animal Ecology, Journal Year: 2018, Volume and Issue: 88(2), P. 247 - 257

Abstract Research addressing the effects of global warming on distribution and persistence species generally assumes that population variation in thermal tolerance is spatially constant or overridden by interspecific variation. Typically, this rationale implicit sourcing one critical maximum (CT max ) estimate per to model spatiotemporal cross‐taxa heat tolerance. Theory suggests such an approach could result biased imprecise estimates forecasts impact from climate warming, but limited empirical evidence support those expectations exists. We experimentally quantify magnitude intraspecific CT among lizard populations, extent which incorporating variability can alter through a biophysical model. To do so, we measured 59 populations 15 Iberian (304 individuals).
