Modern botanists have revisited sites examined by Alexander von Humboldt. Have modern advances made the German polymath's work irrelevant?

Why is active carbon storage being ignored by modelers?
Active carbon pools need to be included for accurate simulation of plant growth patterns under fluctuating environments.

Modelling perennial grass phenology
Predicting phenology can provide insight into better management.
Why are there no Arctic mangroves?
Research from Japan reveals that mangroves can't cope with cold feet.
Daffodils and Snowdrops react differently to warming seasons
Daffodils and Snowdrops need the right temperatures in a few seasons to germinate. Will a changing climate cause problems?
Thermal Ecology to become a hot topic
We might think of flowers in terms of their colour and scent, but what about their temperature? A new review in Annals of Botany looks at the thermal ecology of flowers. In the paper Casper van der Kooi and colleagues...

Conserved thermal performance curves across the geographic range of a gametophytic fern
Species-level responses to environmental change depend on the collective responses of their constituent populations and the degree to which these populations are specialized to local conditions. Thermal tolerance limits...

Seed dormancy regulates germination response to smoke and temperature in a rhizomatous evergreen perennial
Seed dormancy status regulates the response of seeds to environmental cues that can trigger germination. Anigozanthos flavidus (Haemodoraceae) produces seeds with morphophysiological dormancy that are known to germinate...
Stomatal conductance and elevated CO2
Studies have indicated that plant stomatal conductance (gs) decreases in response to elevated atmospheric CO2, a phenomenon of significance for the global hydrological cycle. However, gs increases across certain CO2...

Thresholds for the onset of xylogenesis in juniper
A mismatch between the thresholds of temperature and moisture for the onset of xylogenesis may increase forest vulnerability in semi-arid areas under forecasted warmer and drier conditions.
Thermal acclimation of photosynthesis and dark respiration in white spruce
The results showed moderate thermal acclimation of respiration and no evidence for thermal acclimation of photosynthesis or local genetic adaptation for traits related to thermal acclimation.
Grass florets bet-hedge against unpredictable rainfall in arid landscapes
Seed germination in the arid zone is a high-risk event. For grasses specifically, the ancillary bracts of the floret surrounding the seed have been associated with innate dormancy mechanisms, resulting in infrequent...
Fusarium wilt of cucumber plants is not caused by water shortage
Although leaf wilt occurred in both water stress and FOC infection, the physiological responses were different, especially in leaf spatial distribution.
Snow addition and warming impacts on arctic leaf anatomy and gas exchange
Climatic changes can result in modified leaf anatomy and gas exchange in arctic plants. In a one-year-old field experiment in Greenland, Schollert et al. investigate the effects of increased snow depth and warming on...
