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

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

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.

Testing the evolutionary potential of an alpine plant: Phenotypic plasticity in response to growth temperature far outweighs parental environmental effects and other genetic causes of variation

Journal of Experimental Botany, Journal Year: 2024, Volume and Issue: 75(18), P. 5971 - 5988

Published: July 1, 2024

Abstract Phenotypic plasticity and rapid evolution are fundamental processes by which organisms can maintain their function fitness in the face of environmental changes. Here we quantified evolutionary potential an alpine herb Wahlenbergia ceracea. Utilizing its mixed-mating system, generated outcrossed self-pollinated families that were grown either cool or warm environments, had parents also been environments. We then analysed contribution genetic factors to variation a range phenotypic traits including phenology, leaf mass per area, photosynthetic function, thermal tolerance, reproductive fitness. The strongest effect was current growth temperature, indicating strong plasticity. All except tolerance plastic, whereby warm-grown plants flowered earlier, grew larger, produced more stems compared with cool-grown plants. Flowering onset biomass heritable under selection, early flowering larger having higher relative There little evidence for transgenerational plasticity, maternal effects, genotype×environment interactions. Inbreeding delayed reduced biomass. Overall, found W. ceracea has capacity respond rapidly climate warming via change.

Changes in forest ecosystem stability under climate change in a temperate landscape

Climate change poses significant threats to forests globally. Understanding the relationship between environmental variables and species distribution is crucial for evaluating vulnerability of tree assemblies anticipated climate change. Here, we address whether projected future changes in suitability are related structural stability old-growth forest community Japan.

Elevated Temperature Diminishes Reciprocal Selection in an Experimental Plant‐Pollinator‐Herbivore System

Ecology Letters, Journal Year: 2025, Volume and Issue: 28(1)

Published: Jan. 1, 2025

ABSTRACT The geographic mosaic of coevolution predicts reciprocal selection, the first step in coevolution, to vary with changing biotic and abiotic environmental conditions. Studying how temperature affects selection is essential connect effects global warming on microevolutionary patterns ecological processes underlying them. In this study, we investigated whether influenced between a plant ( Brassica rapa ) its pollinating butterfly herbivore Pieris rapae ). two environments (ambient hot), measured phenotypes plants butterflies, their interactions fitness, which used calculate selection. We found variety traits involved ambient environment, but none hot environment. provide experimental evidence that elevated weakens will help better predict consequences for coevolution.
