Seasonal Assembly of Nectar Microbial Communities Across Angiosperm Plant Species: Assessing Contributions of Climate and Plant Traits

Ecology Letters, Volume 28, Issue 1, January 2025.
Plant–microbe associations are influenced by dispersal, host plant filtering, microbial interactions and abiotic conditions. We inoculated a synthetic community of nectar‐inhabiting microbes into 31 diverse plant species, excluding pollinators, and monitored community trajectory.

Cytotoxic and antiherpetic activity of phloroglucinol derivatives from Mallotus japonicus (Euphorbiaceae).

Chemical and Pharmaceutical Bulletin, 1990
The phloroglucinol derivatives isolated from Mallotus japonicus Muell. Arg. (Euphorbiaceae) and their derivatives were evaluated for their capacity to produce cytotoxicity in HeLa cells and to inhibit the replication of herpes simplex virus type 1 (HSV-1).

Biodiversity as an index of regime shift in the eastern Bering Sea [PDF]

, 2006
Data collected from an annual groundf ish survey of the eastern Bering Sea shelf from 1975 to 2002 were used to estimate biomass and biodiversity indexes for two fish guilds: f latfish and roundfish.

Seed rain into upland plant communities in Hong Kong, China [PDF]

, 2006
Hong Kong is an extreme example of tropical landscape degradation, with no substantial remnants of the original forest cover and a highly impoverished disperser fauna.

Tocopherol(Toc) and sterol composition and concentration in Mallotus japonicus seeds.

Journal of the agricultural chemical society of Japan, 1988
Mallotus japonicus seeds were separated to cotyledons and seed coat. The lipid content in the whole seed was 45.2%; the cotyledon lipid content was higher than the seed coat content. The main components of seed Toc were α-, γ- and δ-Toc. δ-Toc was found at a higher level in the seed -coat than in the cotyledon.

Shifting spawning phenology in Hudson River American Shad

Marine and Coastal Fisheries, Volume 16, Issue 5, October 2024.
Abstract Objective The objectives of this study were to investigate potential shift in the phenology of spawning for the Hudson River American Shad Alosa sapidissima and to identify factors contributing to the decline of the Hudson River shad population. Methods This study utilized American Shad eggs collected from the Long River Ichthyoplankton Survey.

Evolution of secondary metabolites, morphological structures and associated gene expression patterns in galls induced by four closely related aphid species on a host plant species

Molecular Ecology, Volume 33, Issue 16, August 2024.
Abstract Gall‐forming insects induce various types of galls on their host plants by altering gene expression in host plant organs, and recent studies have been conducted for gene expression in galls. However, the evolutionary trajectories of gene expression patterns and the resulting phenotypes have not yet been studied using multiple related species ...

Genetic–environment associations explain genetic differentiation and variation between western and eastern North Pacific rhinoceros auklet (Cerorhinca monocerata) breeding colonies

Ecology and Evolution, Volume 14, Issue 7, July 2024.
Examining adaptive genetic variation of key indicator species, like seabirds, provides greater insights into the forces that drive evolution in marine systems. Here we examined a ddRAD dataset of 19,213 SNPs for 99 rhinoceros auklets (Cerorhinca monocerata) from five west Pacific and 10 east Pacific breeding colonies.

Understanding the power requirements of autonomous underwater systems, Part I: An analytical model for optimum swimming speeds and cost of transport [PDF]

, 2017
Many marine species exhibit capabilities that would be desirable for manmade systems operating in the maritime environment. However, without detracting from the potential, if bioinspiration is to prove beneficial, it is important to have a consistent set

Pest categorisation of Ceroplastes rubens

EFSA Journal, Volume 22, Issue 7, July 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to conduct a pest categorisation of Ceroplastes rubens Maskell (Hemiptera: Coccidae), following the commodity risk assessments of Acer palmatum plants grafted on A. davidii and Pinus parviflora bonsai plants grafted on P. thunbergii from China, in which C.
