Plants maintain climate fidelity in the face of dynamic climate change

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(7)

Published: Feb. 6, 2023

Plants will experience considerable changes in climate within their geographic ranges over the next several decades. They may respond by exhibiting niche flexibility and adapting to changing climates. Alternatively, plant taxa exhibit fidelity, shifting distributions track preferred Here, we examine responses of climates past 18,000 y evaluate extent which 16 dominant North America have exhibited fidelity. We find that 75% consistently fidelity y, even during times most extreme change. Of four do not three—elm ( Ulmus ), beech Fagus ash Fraxinus )—experience a long-term shift realized climatic between early Holocene present day. Plant migrate longer distances better maintain consistent niches across transition periods Today, communities with highest are found regions high topographic microclimate heterogeneity expected resilience, allowing plants locally adjust some amount However, once change buffering region is exceeded, these need broader landscapes but be challenged so because low habitat connectivity regions.

Global research priorities for historical ecology to inform conservation

Endangered Species Research, Journal Year: 2024, Volume and Issue: 54, P. 285 - 310

Published: May 14, 2024

Historical ecology draws on a broad range of information sources and methods to provide insight into ecological social change, especially over the past ∼12000 yr. While its results are often relevant conservation restoration, insights from diverse disciplines, environments, geographies have frequently remained siloed or underrepresented, restricting their full potential. Here, scholars practitioners working in marine, freshwater, terrestrial environments 6 continents various archipelagoes synthesize knowledge fields history, anthropology, paleontology, with goal describing global research priorities for historical influence conservation. We used structured decision-making process identify address questions 4 key priority areas: (1) concepts, (2) co-production community engagement, (3) policy management, (4) climate change impacts. This work highlights ways that has developed matured use novel sources, efforts move beyond extractive practices toward co-production, application management challenges including change. demonstrate this field brought together researchers across connected academics practitioners, engaged communities create apply our shared future.

Tropical Trees Will Need to Acclimate to Rising Temperatures—But Can They?

Plants, Journal Year: 2023, Volume and Issue: 12(17), P. 3142 - 3142

Published: Aug. 31, 2023

For tropical forests to survive anthropogenic global warming, trees will need avoid rising temperatures through range shifts and “species migrations” or tolerate the newly emerging conditions adaptation and/or acclimation. In this literature review, we synthesize available knowledge show that although many tree species are shifting their distributions higher, cooler elevations, rates of these migrations too slow offset ongoing changes in temperatures, especially lowland rainforests where thermal gradients shallow nonexistent. We also rapidity severity warming make it unlikely can adapt (with some possible exceptions). argue best hope for becoming “committed extinction” is individual-level Although several new methods being used test acclimation, unfortunately still do not know if acclimate, how acclimation abilities vary between species, what factors may prevent facilitate Until all questions answered, our ability predict fate forests—and services they provide humanity—remains critically impaired.

Investigating odonates' response to climate change in Great Britain: A tale of two strategies

Abstract Aim Species are largely thought to maintain broadly static niches over time, an assumption underpinning much theoretical ecology including the implementation of ecological models project species' current and future distributions. Here, we assess niche conservatism in odonates Great Britain past six decades by simultaneously quantifying changes species geographic distribution evaluating temporal trends realised climatic niche.

Changes using a principal component analysis quantify overlap, information on both climate averages extremes. Results We show that dragonflies damselflies displayed distinct responses changing conditions. Dragonflies shifting higher latitudes maintained, average, greater consistency their niches, providing evidence for tracking. Greater flexibility increased other hand, more common damselflies. Main Conclusions unveil divergence national scale, casting doubt relevance predicting impacts change this, potentially other, groups species.

Abstract The spatial distribution of individuals within ecological assemblages and their associated traits behaviors are key determinants ecosystem structure function. Consequently, determining the species, how distributions influence patterns species richness across ecosystems today in past, helps us understand what factors act as fundamental controls on biodiversity. Here, we explore niche modeling has contributed to understanding spatiotemporal past biodiversity evolutionary processes. We first perform a semiquantitative literature review capture studies that applied models (ENMs) identifying 668 studies. coded each study according focal taxonomic group, whether used fossil evidence, it relied evidence or methods addition ENMs, scale study, temporal intervals included ENMs. trends publication categories anchor discussion recent technical advances modeling, focusing paleobiogeographic ENM applications. then explored contributions ENMs paleobiogeography, with particular focus examining drivers range dynamics; phylogeography within-lineage macroevolutionary processes, including change, speciation, extinction; community assembly; conservation paleobiogeography. Overall, powerful tools for elucidating patterns. most commonly Quaternary dynamics, but an increasing number use gain important insight into both processes pre-Quaternary times.

Plant-associated microorganisms significantly contribute to plant survival in diverse environments. However, limited information is available regarding the involvement of endophytes responding climate change and their potential enhance host plants' adaptation future environmental shifts. Pinus armandi, endemic China widely distributed climate-sensitive regions, serves as an ideal subject for investigating microbiome interactions that assist plants response. Despite this, a comprehensive understanding diversity, community composition, factors influencing endosperm P. well response these change, remains elusive. In this study, transcriptome data from 55 armandi samples 13 populations were analyzed evaluate composition diversity active predict change. The results revealed variations phylogenetic interaction network between northern southern groups. Temperature precipitation correlated with endophytic species richness diversity. Under projected conditions, group exhibits greater genomic vulnerability anticipates increased threats, reflecting corresponding trend endophytes, particularly within Ascomycota community. consistent threat impacting both hosts emphasizes importance host-related fungi crucial indicators predicting impacts.
