Kristiina Visakorpi, Sebastián Block, Loïc Pellissier, Jonathan M. Levine, Jake Alexander This is a plain language summary of a Functional Ecology research article which can be found here. Plant species growing at high altitudes have adapted to cooler temperatures, shorter summers and less competition from the surrounding vegetation. With climate change, the high elevation environment will increasingly resemble that found at lower elevations today: temperatures … Continue reading The future of Alpine meadows: Can we predict winners and losers in a warmer climate?
Pierre Vollenweider, Géraldine Hildbrand, Davide De Masi, Konstantin Gavazov, Vivian Zufferey, Alexandre Buttler, Georg von Arx This is a plain language summary of a Functional Ecology research article which can be found here. Mountain grasslands are characterized by high biodiversity, low management intensity and plant species adapted to cool and moist climate conditions. With climate warming, however, they may undergo losses in biodiversity. Investigating the … Continue reading Maladaptation versus smart acclimation to expected climate change in wooded pasture grasses
Potter, Tomos; Reznick, David; Coulson, Tim Different species use energy in different ways. For example, rabbits invest heavily in reproduction, producing many small offspring over a short lifespan. At the other extreme, elephants live for a long time, invest more energy in growth, and have only a few large offspring. One approach to describing these different ways of dividing up energy – or different life-history … Continue reading Substantial variation in energy budgets: biology or artefact
Suetsugu, Kenji; Matsubayashi, Jun Green coloration is a defining feature of the plant kingdom, and plants are mostly autotrophic, i.e. they make their own nutrients through photosynthesis. However, several hundreds of plants have lost their photosynthetic ability and have evolved to depend entirely on mycorrhizal fungi (known as full mycoheterotrophy). Since photosynthesis is a fundamental process for plant survival, its loss is one of the … Continue reading The modified underground architecture enhances carbon gains through not photosynthesis but fungal parasitism
Christopher B. Wall, Contessa A. Ricci, Alexandra D. Wen, Bren E. Ledbetter, Delania E. Klinger, Laura D. Mydlarz, Ruth D. Gates, Hollie M. Putnam Coral reefs are threatened by climate change and the increasing frequency and severity of marine heatwaves, which disrupt the important symbiosis between reef building coral animals and their unicellular symbiont algae (Symbiodiniaceae) in a process known as “coral bleaching,” which can lead to widespread coral mortality.In Hawai‘i, the … Continue reading Shifting baselines: Physiological legacies contribute to the response of reef coral to frequent heat waves
Roberts, Emily; Newcomb, Laura; McCartha, Michelle; Harrington, Katie; LaFramboise, Sam; Carrington, Emily; Sebens, Kenneth Many plants and sessile animals invest in mechanical attachment to their habitat by producing structural materials. The cost of this attachment can depend on the amount of structure produced to stay attached, but little is known about how much energy many organisms invest in such structures. One way that scientists evaluate … Continue reading Mussels attach to their habitat using byssal threads, but at what cost?
Pincebourde, Sylvain; Dillon, Michael; Woods, Art When it comes to climate, size matters. Large animals, including humans, feel hot or cold based primarily on air temperature and the strength of incoming sunlight. For these large animals, the temperature of nearby objects is largely irrelevant. Most animals, however, are tiny, and the surfaces they live on, including the soil and rocks, stems and leaves, and even … Continue reading Tell me how small you are and I will tell you how hot you are
Le Pogam, Audrey; O’Connor, Ryan; Love, Oliver; Petit, Magali; Régimbald, Lyette; Vézina, François conditions by increasing their fat store and the mass of their flight muscles. These changes can increase their cold endurance through the production of more heat via shivering. However, birds also increase their fat stores and flight muscle size to provide fuel and muscle force for long migratory flights. Given the similar … Continue reading An Arctic breeding passerine takes advantage of winter phenotypic adjustments to migrate in the cold
Guerrieri, Rossella; Correia, Marta; Martin-Fores, Irene; Alfaro-Sanchez, Raquel; Pino, Joan; Hampe, Arndt; Valladares, F.; Espelta, Josep Greening of our planet has increased over recent decades. This has been attributed mostly to the CO2 fertilization effect on vegetation (particularly forests) though recent studies have highlighted the crucial role of land-use change. Indeed, abandonment of past agricultural and pastureland (in previously deforested areas or marginal mountainous regions) … Continue reading Land-use legacies affect tree ecophysiology and nitrogen availability in secondary beech forests in Mediterranean mountainous areas
Ardanuy, Agnès; Walker, Jennifer; Kritzler, Ully; Taylor, Andy; Johnson, David How do plants influence the soil environment in which they grow? Tackling this question has led to the concept of ‘plant-soil feedback’, which describes reciprocal interactions between plants and their soil environment, leading to either positive or negative effects on plant performance. While we know that soil biota can have direct effects on plant nutrition … Continue reading Nutrient exchange between tree and soil symbionts determine performance feedback in Alder
