Genetic diversity in the traditional cultivars and wild ancestor of near-threatened Japanese iris (Iris ensata Thunb.)NARA Subscribed
Wild relatives of cultivars are crucial sources of genetic variation for further enhancement, yet they face potential threats due to contemporary environmental changes. Iris ensata var. spontanea , a wild progenitor of the Japanese iris cultivars ( I. ensata var. ensata ), is extensively cultivated in Japanese gardens, is distributed across mesic meadows and wetlands in Japan and East Asia. This species is currently threatened...
Glaciers host ecosystems comprised of biodiverse and active microbiota. Among glacial ecosystems, less is known about the ecology of ice caps since most studies focus on valley glaciers or ice sheet margins. Previously we detailed the microbiota of one such high Arctic ice cap, focusing on cryoconite as a microbe‐mineral aggregate formed by cyanobacteria. Here, we employ metabolomics at the scale of an entire ice cap to reveal...
An urgent need for COP27: confronting converging crisesNARA Subscribed
The last 12 months have provided further evidence of the potential for cascading ecological and socio-political crises that were warned of 12 months ago. Then a consensus statement from the Regional Action on Climate Change Symposium warned: “the Earth’s climatic, ecological, and human systems are converging towards a crisis that threatens to engulf global civilization within the lifetimes of children now living.” Since then,...

Taxon interactions control the distributions of cryoconite bacteria colonizing a High Arctic ice capNARA Subscribed
Microbial colonization of glacial ice surfaces incurs feedbacks which affect the melting rate of the ice surface. Ecosystems formed as microbe–mineral aggregates termed cryoconite locally reduce ice surface albedo and represent foci of biodiversity and biogeochemical cycling. Consequently, greater understanding the ecological processes in the formation of functional cryoconite ecosystems upon glacier surfaces is sought. Here,...
Genetic variants of K udoa septempunctata ( M yxozoa: M ultivalvulida), a flounder parasite causing foodborne diseaseNARA Subscribed
Foodborne disease outbreaks caused by raw olive flounders ( Paralichthys olivaceus ) parasitized with Kudoa septempunctata have been reported in Japan. Origins of olive flounders consumed in Japan vary, being either domestic or imported, and aquaculture‐raised or natural. Although it is unknown whether different sources are associated with different outcomes, it is desirable to identify whether this is the case by determining...
Mass flowering of the tropical tree S horea beccariana was preceded by expression changes in flowering and drought‐responsive genesNARA Subscribed
Community‐level mass flowering, known as general flowering, which occurs in S outh‐ E ast A sia at supra‐annual irregular intervals, is considered a particularly spectacular phenomenon in tropical ecology. Recent studies have proposed several proximate factors inducing general flowering, such as drought and falls in minimum temperature. However, limited empirical data on the developmental and physiological processes have been...
