  1. 1. Thermal adaptation along a latitudinal gradient in damselflies

    Författare :Viktor Nilsson-Örtman; Frank Johansson; Karl Gotthard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Growth rate; metabolic theory of ecology; universal temperature dependence; environmental gradients; thermal performance; thermal sensitivity; environmental variability; optimality theory; life history; acclimation; size structure; competition; cannibalism; intraguild predation;

    Sammanfattning : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.

  2. 2. Thermal plasticity and limitations in tropical trees

    Författare :Maria Wittemann; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acclimation; African tropical forest; chlorophyll fluorescence; climate change; drought; hydraulic; montane; photosynthesis; respiration; successional strategies; temperature; tropical trees; warming;

    Sammanfattning : Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate close to their thermal limits because of a historically and seasonally stable environment. LÄS MER

  3. 3. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

    Författare :Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER

  4. 4. Thermal tolerance in teleost fish –importance of cardiac oxygen supply, ATP production and autonomic control

    Författare :Andreas Ekström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acclimation; coronary; CTmax; enzyme; global warming; heart; mitochondria;

    Sammanfattning : Temperature tolerance is a key determinant of the resilience and adaptability of fish facing a warmer and more thermally variable future with climate change. Yet, the underlying physiological mechanisms determining the critical thermal maximum (CTmax) are poorly understood. LÄS MER

  5. 5. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea

    Författare :Friederike Ermold; Anssi Laurila; Jukka Jokela; Kerstin Johannesson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; thermal adaptation; evolution; Baltic Sea; Biotest Basin; ecological interactions; biological invasions; phenotypic plasticity; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. LÄS MER
