Competitive exclusion, not predation, likely drove the decline in native fish diversity following carnivorous fish introductions to Lake Titicaca in the mid‐20th century

Journal of Fish Biology, EarlyView.
Abstract Lake Titicaca is a continental centre for ichthyological biodiversity, with over 90% of native species being endemic. However, these species face significant threats from invasive species, particularly from invasive salmonids and invasive Argentine pejerrey.

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Thermal history, collisional history, and structure of the CK‐chondrite parent body

Meteoritics &Planetary Science, EarlyView.
Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.

Thermal history of an amoeboid olivine aggregate in the early solar nebula

Meteoritics &Planetary Science, EarlyView.
Abstract Carbonaceous chondrites commonly contain amoeboid olivine aggregates (AOAs). Here, we investigated an AOA in the CR chondrite Y‐793261. This AOA contains an unstable assemblage of forsterite and quartz. We found a rare occurrence of enstatite and quantitatively discuss its formation process.

Extending the limits of algal growth and stress resilience – the desert alga Chlorella ohadii as an emerging model

New Phytologist, EarlyView.
Multiple facets of Chlorella ohadii biological properties and potential as a research model and biotechnology platform. Summary Since its isolation from the sand dunes of the Negev Desert over a decade ago, the unicellular green alga Chlorella ohadii has turned into a reference organism for studying photosynthesis, metabolism, and abiotic stress ...

Integrated Metabolomics and Selection Signal Analysis Provide Insights Into the Selection for Flavonol Biosynthesis Associated With Lettuce Quality Improvement

Plant Biotechnology Journal, EarlyView.
ABSTRACT Lettuce is a critical leafy vegetable consumed worldwide and is a substantial dietary source of health‐promoting compounds. Exploring changes in metabolism during lettuce domestication under artificial selection conditions is important to facilitate further breeding and cultivation for quality improvement.
