Loss or duplication of key regulatory genes coincides with environmental adaptation of the stomatal complex in Nymphaea colorata and Kalanchoe laxiflora

Horticulture Research, 2018
How plants breathe in different environments Researchers in China have shown how plants adapted to different environments by altering the structure of pores used for gas and water exchange, known as stomata.

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Flavonoids from the flowers of Nymphaea alba L.

Acta Societatis Botanicorum Poloniae, 2014
Ten flavonoids were obtained from the flowers of Nymphaea alba L. Their structures were determined mainly on the basis of spectral analyses (UV, 'H NMR, MS). The following aglycons were isolated: quercetin, kaempferol, isokaempferide and apigenin as well

Taxonomic and functional diversity of noctuoid moths in a Mediterranean coastal area: implications for dune conservation in a long‐term ecological research eLTER site

Insect Science, EarlyView.
This study investigates the taxonomic and functional diversity of noctuoid moths in a protected coastal dune system in Central Italy, revealing strong ecological associations between moth assemblages and dune zonation. Differences in species composition and trait attributes, along with the presence of habitat‐exclusive species, highlight the role of ...

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

Integrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes

Methods in Ecology and Evolution, EarlyView.
Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

Bioaccumulation, sources and health risk assessment of polycyclic aromatic hydrocarbons in Lilium davidii var. unicolor.

PLoS ONE
Dietary uptake is the main pathway of exposure to polycyclic aromatic hydrocarbons (PAHs). However, there is no data regarding the pollution and health risks posed by PAHs in Lilium davidii var. unicolor. We measured the concentrations of 16 PAHs in lily
