ACCESS TO URBAN COOL AND GREEN SPACES FOR OLD ADULTS IN GOTHENBURG – A GIS-BASED ANALYSIS OF RADIANT HEAT
(2023-01-19)Old adults are particularly vulnerable against heat stress. Considering the ageing society and the projected increase of heat events, planning for heat-resilient urban environments for old adults will become increasingly ... -
ARCTIC MYCORRHIZAL INTERACTIONS UNDER CLIMATE CHANGE
(2022-07-06)The Arctic is experiencing climate change at an extreme rate, affecting both the rates of plant growth and nutrient cycling. Due to the changes in temperature, but also in nutrient cycling, with increased nutrient ... -
ARCTIC PLANT COMMUNITIES RISE WITH TEMPERATURE Plant functional traits as a tool to predict global climate change
(2022-07-06)Global warming occurs at a rate at least three-fold in the arctic regions compared to the rest of the world. Here, plant community functional traits were assessed in response to experimental warming in three arctic areas ... -
ÄLDRE EKARS TILLVÄXT - Naturvård, föryngring och inventeringsmetoder
(2022-07-06)Ekar (Quercus sp) utgör en viktig del av den svenska biologiska mångfalden då mer är 2000 arter kan anknytas till äldre ekars bark, krona och håligheter. Eken var betydligt vanligare förr, men skogsbruket och förändrad ... -
Återhämtning efter värmestress – vid vilka förutsättningar är återhämtningen som mest effektiv hos den tropiska trädarten Maesa lanceolata
(2022-12-02)Global uppvärmning är ett faktum, därmed blir värmeextremer allt vanligare. Den stigande temperaturen utsätter växter i tropiska klimat för värmestress, som kan skada fotosystem II och därmed inaktivera fotosyntesen. För ... -
Can cellular osmolarity be used as a predictor for drought tolerance in common bean?
(2022-08-16)Common bean, Phaseolus vulgaris, is a protein and nutrient rich food source grown around the world. Rwanda has one of the highest per capita consumption rates in the world. With climate change threatening food security, ... -
CAN LEAF LEVEL GAS EXCHANGE BE USED AS A PREDICTOR FOR DROUGHT TOLERANCE IN COMMON BEAN (PHASEOLUS VULGARIS)?
(2022-08-16)This study aimed to examine drought tolerance among a variety of landraces of the species Phaseolus vulgaris to discover whether leaf level gas exchange can be used as a predictor for drought tolerance. Beans of different ... -
Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities
(2023-01-26)Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological ... -
Differences in velocity between the sexes and stages of courtship in a dance fly
(2022-02-17)Dance flies (Diptera: Empididae: Empidinae) are famous for their elaborate mating behaviour, which can be broken down to three distinct stages in adults: hunting, swarming, and mating. In many species, males hunt for prey ... -
EFFECT OF ENDOCRINE DISRUPTING MIXTURES AND CHEMICALS ON THE OXYGEN CONSUMPTION RATE OF ZEBRAFISH LARVAE
(2022-08-08)Chemicals affecting the endocrine system, so called endocrine disrupting chemicals (EDC’s), have been steadily increasing in the environment over the last 40 years. EDCs are harmful chemicals since they can act through ... -
Effect of suspended sediment on embryos and larvae of the cold‐water coral Lophelia pertusa
(2022-09-13)The cold-water coral Lophelia pertusa (syn. Desmophyllum pertusum) provides importanthabitats in deep-sea ecosystems, allowing for a biodiversity similar to that of tropical coral reefs. Anthropogenic activities like ... -
Effects of marine contaminant mixtures on the copepod genus Pseudocalanus. How ambient contaminant mixtures affect mortality, food intake and fecal pellet production.
(2022-10-27)Chemicals are present in almost every part of human society and their benefits to our everyday life are undeniable. Besides those benefits, chemicals are known to cause harm to both human health and the environment. ... -
En jämförelse av användningsområden och kemisk sammansättning av skal från blåmusslor och stillahavsostron
(2022-07-06)Invasiva stillahavsostron har etablerats i stora bestånd i svenska vatten under de senaste 16 åren. Ett förslag till hantering av dessa skulle vara bortrensning från områden där de orsakar problem, vilket skulle resultera ... -
En kartläggning av användningsområden för kött från stillahavsostron
(2022-07-06)Den invasiva arten stillahavsostron (Magallana gigas) har etablerats längs med svenska västkusten sedan år 2007 och därmed är det relevant att se över förvaltningen av dem. Ett tillvägagångssätt skulle vara att avlägsna ... -
Endophytic fungi in living trees - are communities affected more by tree species, tree age, or geographic origin?
(2022-08-16)Endophytic fungi are ubiquitous in living vascular plants and have been identified in most terrestrial environments. The endophytes may have various ecological roles such as commensals, symbionts and latent invaders. Woody ... -
