Abstract:
... The desiccation tolerance of the intertidal seagrass Zostera japonica has been demonstrated in a number of studies; however, the factors limiting expansion of intertidal seagrass species into subtidal zones remain controversial. We transplanted Z. japonica shoots from the intermediate intertidal zone into the plots with and without Z. marina shoots in both the lower intertidal and shallow subtidal ...

Abstract:
... With their imposing grandeur, the small number of very tall tree species attract a disproportionate amount of scientific study. We right this bias by focusing here on the shorter trees, which often grow in the shade of the giants and many other places besides. That tall trees are so restricted in distribution indicates that there are far more habitats available for small trees. We discuss some lea ...

Abstract:
... The desiccation tolerant (DT) fern species Crepidomanes inopinatum and Loxogramme abyssinica often grow together in the understory of KwaZulu-Natal Afromontane forests. Crepidomanes inopinatum is a “filmy” fern that dries rapidly because it lacks a cuticle; by contrast L. abyssinica possesses a cuticle, and therefore dries slowly. It was predicted that because C. inopinatum dries quickly, this spe ...

Climate change has compromised global cereal production, particularly in semiarid regions where small changes in rainfall and temperature or excessive heat can have large effects on crop productivity. Central Asia is particularly vulnerable to climate change, but the understanding of the impacts of climate change on yields is incomplete for this region. We used fixed-effect panel regressions to qu ...

To gain insights into the role of πₜₗₚ for drought resistance of temperate perennial gras ...
