Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Data from: The effects of spatial scale and isoscape on consumer isotopic niche width

, 2017
1. The mean and variance of ecological variables are dependent on sampling attributes such as the coverage of environmental heterogeneity (sampling extent) and spatial scale.

Trait convergence under warming: drought tolerance, not thermal limits, mediates native–invader dynamics in alpine ecosystems

Oikos, EarlyView.
Climate warming and plant invasions jointly alter alpine ecosystems, but the mechanisms underlying these interactions remain unclear. A key to predicting ecosystem vulnerability is whether native and invasive species can sustain performance as conditions warm.

Seasonal variation in trophic structure and community niche dynamics of an Arctic coastal community of marine vertebrates

Arctic Science
Temporal variation in food web structure is widespread among highly seasonal environments, such as the Arctic, and is driven by changes in resource availability.

Does behaviour determine isotopic niche width?

, 2022
We are using a novel combination of acoustic telemetry and stable isotope analysis ( that provide the necessary tools for a better understanding of behaviour and spatial movement in an aggregation of Raja undulata Lacepède 1802 within a ...

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Evolution of photoperiod insensitivity drove the westward expansion of broomcorn millet

PLANTS, PEOPLE, PLANET, EarlyView.
This research highlights how ancient farming communities adapted crops to challenging environments, enabling the spread of agriculture across Eurasia. By demonstrating that broomcorn millet evolved reduced sensitivity to day‐length, the study explains how this crop could support food production in regions with short growing seasons and long summer days.

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...
