Small, Volume 18, Issue 35, September 1, 2022., 2022 Marine calcifiers are widely believed to be impaired by ocean acidification, but this concept has been increasingly challenged by recent evidence. This systematic review and meta‐analysis of nearly 1000 studies reveal that many calcifiers are indeed more resistant to ocean acidification than initially thought, which can result from the positive effects

Journal of the World Aquaculture Society, Volume 52, Issue 6, Page 1290-1311, December 2021., 2021 Abstract Chondracanthus chamissoi is part of the diet of coastal people from Peru and is exported dehydrated to Asian countries for direct consumption. Although it is considered endemic to Peru and Chile, its range has extended to distant regions, such as Korea, Japan, and France. Using morphological and molecular approaches, we examined specimens from

Origin of Low-26Al/27Al Corundum/Hibonite Inclusions in Meteorites
The Astrophysical Journal, 2023 Most meteoritic calcium-rich, aluminum-rich inclusions formed from a reservoir with ^26 Al/ ^27 Al ≈ 5 × 10 ^−5 , but some record lower ${({}^{26}\mathrm{Al}/{}^{27}\mathrm{Al})}_{0}$ , demanding they sampled a reservoir without live ^26 Al.

Ecology and Evolution, Volume 10, Issue 19, Page 10463-10480, October 2020., 2020 Hypogeococcus pungens is a species complex native to South America. Some of its members are cactophilic, and one of them has been reported as a pest threatening cactus diversity in the Caribbean and North America. Using a combination of genome‐wide SNPs and mtDNA, we found that the complex comprises at least five different species, each strongly ...

Resistance, resilience, and vulnerability of social‐ecological systems to hurricanes in Puerto Rico
Ecosphere, Volume 11, Issue 10, October 2020., 2020 Abstract Subject to hurricane disturbance for millennia, natural ecosystems of Puerto Rico exhibit clear patterns of resistance (e.g., many tree species have little immediate storm‐related mortality) and resilience (e.g., leaf litterfall and stream chemistry returned to pre‐hurricane levels in as little as five years).
