Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

American Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Clay minerals and elemental composition of smectites in the marine sediment from the southwest Ross Sea and implication for their provenance and sediment input changes after the last glacial period

Geoscience Letters
Smectite in detrital sediments can be composed of various proportions of Al, Mg, and Fe, indicating the sediment sources derived from the bedrock or from the sedimentary strata. Comparing the elemental composition of smectites can help to define sediment

Dispersal and establishment both limit colonization during primary succession on a glacier foreland [PDF]

, 2009
Plant colonization can be limited by lack of seeds or by factors that reduce establishment. The role of seed limitation in community assembly is being increasingly recognized, but in early primary succession, establishment failure is still considered ...

Greenlandic water bears reveal a new morphological trait of external head sensory organs

Scientific Reports
Tardigrades are microscopic panarthropods renowned for their ability to undergo cryptobiosis. While integrative taxonomy of tardigrades has been intensively applied in the description of tardigrade species over the past two decades, many details of their

The Morteratsch Glacier [PDF]

Nature, 1881
During my stay in the Engadine this summer I took the opportunity of making a few observations relative to the movement of the Morteratsch Glacier, which may be of interest to some of your readers. These observations were taken inside the artificial cave of the above glacier in preference to the surface, as I thereby obtained a more direct measurement ...

Design of a Sustainable Polysaccharide‐Lignocellulosic‐Mineral Granular Biocomposite Sorbent for Methylene Blue Removal

Journal of Applied Polymer Science, EarlyView.
This manuscript describes the preparation of four types of spent coffee ground‐based adsorbents. Herein, the influence of the alkali pre‐treatment step (different NaOH concentrations) as well as the effect of crosslinking with epichlorohydrin is described.
