Contrasting strategies in Amazonian trees are related to stem and twig wood density variation

Gisele Biem Mori, Jochen Schöngart, Juliana Schietti, J. Ethan Householder, Michelle Robin, Florian Wittmann, Lourens Poorter, Maria Teresa Fernandez Piedade This is a plain language summary of a Functional Ecology research article which can be found here. Tropical tree species vary immensely in their characteristics, enabling different species to occupy particular environments where they are best suited. Wood density is a characteristic related to growth, … Continue reading Contrasting strategies in Amazonian trees are related to stem and twig wood density variation

How multiple stressors interact and affect leaf decomposition in freshwaters.

Graciela Medina Madariaga, Verónica Ferreira, Roshni Arora, India Mansour, Gwendoline M. David, Sonja C. Jähnig, Fengzhi He This is a plain language summary of a Functional Ecology research article which can be found here. Different stressors can affect ecological functions in freshwater ecosystems, such as the rate at which leaves decompose after falling into the water. The effects of individual stressors on leaf decomposition have … Continue reading How multiple stressors interact and affect leaf decomposition in freshwaters.

Does urban warming constrain spider’s body size?

Valentin Cabon, Hervé Quénol, Benoît Deletre, Louis Copin, Vincent Dubreuil, Benjamin Bergerot This is a plain language summary of a Functional Ecology research article which can be found here. In cities, the climate varies from the countryside to the centre, with temperature inside the city often higher on average, a phenomenon called the urban heat island (UHI) effect. Temperature variations at the scale of an … Continue reading Does urban warming constrain spider’s body size?

Acclimating to warm temperatures is costly for reproduction in copepods with high thermal limits

Samuel N Bogan, Olivia I Porat, Michael J Meneses, and Gretchen E Hofmann This is a plain language summary of a Functional Ecology research article which can be found here. Cold-blooded animals (ectotherms) can withstand stressfully warm temperatures by possessing either (i) a high thermal limit below which they can maintain normal biological functions or (ii) an ability to increase that limit by acclimating to … Continue reading Acclimating to warm temperatures is costly for reproduction in copepods with high thermal limits

High temperatures increase the nutrient demands for a small aquatic plant

Graydon J. Gillies, Amy L. Angert, Takuji Usui This is a plain language summary of a Functional Ecology research article which can be found here. To persist, species must confront competitors that require the same resources. When two competitors are growing in an environment where a certain resource is scarce, the competitor that is able to maintain a growing population with less of that limiting … Continue reading High temperatures increase the nutrient demands for a small aquatic plant

Above-ground leaf and below-ground root differ in their response to long-term grazing: root traits are more sensitive

Jinting Cai, Xiaobin Pan, Yingli Xiao, Yue Wang, Guangyin Li, Yao Wang, Minna Zhang, Ling Wang This is a plain language summary of a Functional Ecology research article which can be found here. Livestock grazing is a complex disturbance that affects grassland ecosystem function through foraging, trampling and excreta. A promising way to understand the consequences of grazing on grassland ecosystem functioning is to focus … Continue reading Above-ground leaf and below-ground root differ in their response to long-term grazing: root traits are more sensitive

Leaf fluctuating asymmetry is not a reliable indicator of stress

Maria Májeková, Bettina Springer, Viktoria Ferenc, Michal Gruntman, Katja Tielbörger This is a plain language summary of a Functional Ecology research article which can be found here. For any organism with bilateral structures, if everything goes well during development, both left and right sides should be perfectly symmetric. Any stress experienced during development contributes to tiny imperfections, evident as subtle asymmetries between the left and … Continue reading Leaf fluctuating asymmetry is not a reliable indicator of stress

Dietary restriction extends lifespan across different temperatures in the fruit fly

Eleanor J Phillips, Mirre J P Simons This is a plain language summary of a Functional Ecology research article which can be found here. Restricting food intake extends lifespan across species, termed dietary restriction. Despite a lot of research into the physiology of dietary restriction, we have not fully pinpointed the underlying mechanisms nor the precise components of the diet responsible. Moreover, we still do … Continue reading Dietary restriction extends lifespan across different temperatures in the fruit fly
