Integrative Conservation, EarlyView.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

PLANTS, PEOPLE, PLANET, EarlyView.Trees in cities provide a great number of benefits to people and nature, but they are challenged by harsh conditions. Trees rely on helpful fungi in their roots to get essential nutrients from the soil, but we do not know which of these fungi are resistant to city landscapes.

PLANTS, PEOPLE, PLANET, EarlyView.Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

The Cinderella tree, Quillaja saponaria – A soap story
PLANTS, PEOPLE, PLANET, EarlyView.Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

PLANTS, PEOPLE, PLANET, EarlyView.Major staple crops are often introduced and cultivated in monocultures. Yams are staple crops native to the majority of low‐ and middle‐income countries and can provide an alternative to introduced staple crops. We showed that lesser yams cultivated together with teak trees (planted at the border of the farm) are more profitable than lesser yam ...

Rare Metals, EarlyView.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Shuitu Baochi Xuebao, 2016 运用分形模型，结合野外调查和室内试验分析汉中市荒草地整治后耕作层土壤颗粒分形特征，探讨土壤颗粒分形维数与土壤质地、粒径组成以及养分含量的关系，建立整治后耕作层土壤分形维数预测函数。结果表明：（1）整治后土壤颗粒分形维数D介于2.55～2.95之间，均值为2.77，标准差为0.134，土壤颗粒分形维数与土壤质地有一定的关系，表现为土壤质地越细，分形维数越大。（2）土壤颗粒分形维数主要是由黏粒含量决定，分形维数与黏粒含量呈显著线正相关（R2=0.978 0）；利用分形维数与土壤黏粒（≤0.002 mm ...

Computer simulation for fractal aggregates on nonlattice substrates(无格点基底表面分形凝聚体的计算机模拟)
Zhejiang Daxue xuebao. Lixue ban, 2000 对具有周期性边界条件的无格点正方形基底表面分形凝聚体的形成进行了计算机模拟。凝聚体由二种大小不同的圆盘组成。结果表明，凝聚体的分形维数几乎与表面覆盖率成正比，其斜率随圆盘的平均直径的增大而减小。当表面覆盖率很小时，分形维数几乎与圆盘的平均直径无关，约为1.45；当表面覆盖率较大时，分形维数随圆盘的平均直径的增大而减小。
