Pollinators are under threat. A meta-analysis reveals that the combination of agrochemicals, parasites and malnutrition has a cumulative negative effect on bees, and that pesticide–pesticide interacti...
When trouble looms, the fish-scale geckos of Madagascar resort to what might seem like an extreme form of self-defense — tearing out of their own skin. Their unusually large, overlapping scales flake...
Astronomers using the super-sharp radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, lea...
The trial was conducted to evaluate the effects of sea buckthorn leaves (SBL) on meat flavor in broilers during heat stress. A total 360 one-day-old Arbor Acre (AA) broilers (male) were randomly allot...
A transversely holomorphic foliation on a compact complex manifold, exhibits a compact stable leaf if and only if the set of compact leaves is not a zero measure subset of the manifold.
Abstract: Let R be an o-minimal expansion of the real field. We introduce a class of Hausdorff limits, the T-infinity limits over R, that do not in general fall under the scope of Marker and Steinhorn...
The main aim of this study was to assess the free lipid composition of plant community in a Chinese peatland. Twelve plant species from the Dajiuhu Peatland were analyzed for the compositions of n-al...
Molecular composition and compound-specific carbon and hydrogen stable isotope ratios of n-alkanes are presented for leaves of grass, reeds and trees from five regions extending between latitudes 22°...
We define leaves and trajectories for schemes endowed with a vector field. With the help of these tools, we are able to give a geometrical interpretation and to generalize several results and constru...
We prove the Poisson geometric version of the Local Reeb Stability (from foliation theory) and of the Slice Theorem (from equivariant geometry),which is also a generalization of Conn’s linearization t...
In this paper, we provide algorithms to rank and unrank certain degree-restricted classes of Cayley trees. Speci cally, we consider classes of trees that have a given set of leaves or that have a xe...
The leaves are packed in the buds, occupying the whole bud volume. They can do so being flat, enrolled, or folded, in different ways. This <lling law>>, underestimated before, has many consequences...
Platanus tree leaves were successfully used as a novel sorbent for removing of methylene blue (MB) dye from aqueous solutions. A 23 full factorial design was performed for screening of the main factor...
该文对薇甘菊及其所在群落内19种植物(草本和木本)的叶片透射率、反射率和光合特征指标进行了测定, 结果表明:薇甘菊与其它植物透射和反射图谱的变化趋势都比较相近, 在各个光学特征指标与光合相关指标的相互关系中, 薇甘菊并没有表现出区别于同一群落内其它植物的特征。从平均值来看, 200-800 nm下叶片反射率和透射率由大到小依次为: 薇甘菊>草本植物>木本植物, 薇甘菊各光学植被指标(SR680、S...
From the leaves of Chloroxylon swietenia DC., 5 known secondary metabolites, namely 6, 8-diprenylumbelliferone (1), bergaptan (2), isopimpinellin (3), tritriacontanol (4), and isoquercetrin (5), were ...
