Loss of top-down biotic interactions changes the relative benefits for obligate mutualists.

Proc Biol Sci 2019 Feb;286(1897):20182501

6 School of Biology, University of Leeds , Leeds LS2 9JT , UK.

The collapse of mutualisms owing to anthropogenic changes is contributing to losses of biodiversity. Top predators can regulate biotic interactions between species at lower trophic levels and may contribute to the stability of such mutualisms, but they are particularly likely to be lost after disturbance of communities. We focused on the mutualism between the fig tree Ficus microcarpa and its host-specific pollinator fig wasp and compared the benefits accrued by the mutualists in natural and translocated areas of distribution.

Release from natural enemies mitigates inbreeding depression in native and invasive populations.

Ecol Evol 2019 Mar 18;9(6):3564-3576. Epub 2019 Feb 18.

Geobotany & Botanical Garden, Institute of Biology Martin-Luther-University Halle-Wittenberg Halle (Saale) Germany.

Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success of plant invasions if introduced populations experience a release from attack by natural enemies relative to their native conspecifics. Here, we investigate whether inbreeding affects plant infestation damage, whether inbreeding depression in growth and reproduction is mitigated by enemy release, and whether this effect is more pronounced in invasive than native plant populations.

Ecol Evol 2019 Mar 1;9(6):3251-3263. Epub 2019 Mar 1.

Department of Forest and Conservation Sciences, Faculty of Forestry The University of British Columbia Vancouver British Columbia Canada.

Genetic structure and major climate factors may contribute to the distribution of genetic diversity of a highly valued oil tree species (yellowhorn). Long-term over utilization along with climate change is affecting the viability of yellowhorn wild populations. To preserve the species known and unknown valuable gene pools, the identification of genetic diversity "hotspots" is a prerequisite for their consideration as in situ conservation high priority.

Increased expression diversity buffers the loss of adaptive potential caused by reduction of genetic diversity in new unfavourable environments.

Biol Lett 2019 Jan;15(1):20180583

1 Key Laboratory of Plant Resources and Beijing Botanical Garden, Institute of Botany, Chinese Academy of Sciences , Beijing 100093 , People's Republic of China.

Mechanisms underlying adaptation to rapid environmental change are issues in evolutionary biology. It is widely accepted that reduction in genetic diversity when suddenly exposed to an unfavourable environment limits the adaptive potential of populations. With growing empirical evidence that expression diversity is likely to increase in the new environment, the role that expression diversity plays in adaptation needs to be theorized. Read More

Superb autorotator: rapid decelerations in impulsively launched samaras.

J R Soc Interface 2019 Jan;16(150):20180456

1 Department of Integrative Biology, University of California , Berkeley, CA 94720 , USA.

Autorotation of botanical samaras, with a consequent reduction in their rate of descent, increases dispersal range in the presence of horizontal winds. Samaras in initial free fall from rest pass through a brief transitional phase prior to reaching their minimum rate of descent and stable autorotation. By contrast, intense wind gusts and elastic recoil of tree branches can produce impulsive samara detachment and accelerate them rapidly through the air. Read More

Microarray Based Functional Analysis of Myricetin and Proteomic Study on Its Anti-Inflammatory Property.

Biomed Res Int 2019 7;2019:3746326. Epub 2019 Mar 7.

Core Research Program 1515, Key Laboratory for Food Science and Biotechnology of Hunan Province, College of Food Science and Technology, Hunan Agricultural University, Changsha 410128, China.

Myricetin has been reported as a promising chemopreventive compound with multiple biofunctions. To evaluate its influence on gene expressions in genome-wide set and further investigate its anti-inflammatory property, the present study performed Gene Ontology and Ingenuity Pathway Analysis (IPA) to describe the basic gene expression characteristics by myricetin treatment in HepG2 cells, confirmed its multi-biofunction by real-time fluorescent quantitative PCR (RT-qPCR), and further verified its anti-inflammatory property by Western blotting and bio-plex-based cytokines assay. The IPA data showed that 337 gene expressions (48% of the top molecules) are disturbed over 2-fold, and the most possible biofunctions of myricetin are the effect on "cardiovascular disease, metabolic disease, and lipid metabolism," via regulation of 28 molecules with statistic score of 46.
