Cold adaptation drives variability in needle structure and anatomy in Pinus sylvestris L. along a 1,900 km temperate-boreal transect

Occupancy of cold habitats by evergreen species requires structural modification of photosynthetic organs for stress resistance and longevity. Such modifications have been described at interspecific level, while intraspecific variation has been underexplored. To identify structural and anatomical traits that may be adaptive in cold environments, we studied intraspecific variability of needles of S

In search of academic legitimacy : The current state of scholarship on graffiti and street art

Much has changed since the 1960s when the first scholarship on contemporary graffiti appeared. The current paper is an attempt to outline and contextualize a number of recurrent challenges facing researchers of graffiti and street art, as well as developments that have taken place in this scholarly field. The aim of creating this outline is to assist in increasing the amount, and improving the qua

Lead-Free, Air-Stable All-Inorganic Cesium Bismuth Halide Perovskite Nanocrystals

Lead-based perovskite nanocrystals (NCs) have outstanding optical properties and cheap synthesis conferring them a tremendous potential in the field of optoelectronic devices. However, two critical problems are still unresolved and hindering their commercial applications: one is the fact of being lead-based and the other is the poor stability. Lead-free all-inorganic perovskite Cs3Bi2X9 (X=Cl, Br,

Ultrasensitive and Fast All-Inorganic Perovskite-Based Photodetector via Fast Carrier Diffusion

Low trap-state density, high carrier mobility, and efficient charge carrier collection are key parameters for photodetectors with high sensitivity and fast response time. This study demonstrates a simple solution growth method to prepare CsPbBr3 microcrystals (MCs) with low trap-state density. Time-dependent photoluminescence study with one-photon excitation (OPE) and two-photon excitation (TPE) i

Local adaptation studies and conservation : Parasite-host interactions between the endangered freshwater mussel Unio crassus and its host fish

Parasite-host interactions can involve strong reciprocal selection pressure, and may lead to locally adapted specializations. The highly threatened unionoid mussels are temporary parasites on fish, but local adaptation has not yet been investigated for many species. Patterns of local adaptation of one of Europe's most threatened unionoids, the thick-shelled river mussel (Unio crassus) were investi

Classifying multi-model wheat yield impact response surfaces showing sensitivity to temperature and precipitation change

Crop growth simulation models can differ greatly in their treatment of key processes and hence in their response to environmental conditions. Here, we used an ensemble of 26 process-based wheat models applied at sites across a European transect to compare their sensitivity to changes in temperature (-2 to +9°C) and precipitation (-50 to +50%). Model results were analysed by plotting them as impact

A future for the past of spectacular desert vernacular

Desert vernacular architecture is a product of a sustainable building cycle. Desert local inhabitants inherited the traditional way of building from their ancestors developed and then transferred knowledge from one generation to another. This building and cultural cycle is about to disappear in many desert vernacular settlements of the world. Global ambitions and socio-economic developments are so
