Oikos, EarlyView.Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Journal of Animal Reproduction and Biotechnology, 2015 Cryopreservation of boar semen is continually researched in reproductive technologies and genetic resource banking in breed conservation. For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of ...

On the Persistence of Homogeneous Matter [PDF]
, 2004 Some recent philosophical debate about persistence has focussed on an argument against perdurantism that discusses rotating perfectly homogeneous discs (the `rotating discs argument'; RDA). The argument has been mostly discussed by metaphysicians, though

Oikos, EarlyView.Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...

Tyrosinase inhibitory components from Aloe vera and their antiviral activity
Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 A new compound, 9-dihydroxyl-2'-O-(Z)-cinnamoyl-7-methoxy-aloesin (1), and eight known compounds (2–9) were isolated from Aloe vera. Their structures were elucidated using 1D/2D nuclear magnetic resonance and mass spectra. Compound 9 exhibited reversible

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin
People and Nature, EarlyView.Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.

Reversible Nanocomposites With Carbon Nanotubes as the Diene in the Diels–Alder Reaction
Polymer Composites, EarlyView.Scheme of the reversible nanocomposites through DA and rDA reactions with participation of carbon nanotubes. ABSTRACT Carbon nanotubes (CNTs) often require surface functionalization to facilitate uniform distribution and address issues related to aggregation. Due to the sp2 hybridized carbon atoms on their surface, CNTs readily participate in the Diels–
