Contrasting effects of rhizosphere and sediment microbiota on seagrass performance in response to a simulated marine heatwave

Journal of Ecology, EarlyView.
We experimentally disrupted below‐ground microbial communities to test their role in the growth and survival of the seagrass Zostera muelleri under two marine heatwave scenarios. Seagrass leaf growth declined with rhizosphere microbiome disruption across all temperature and sediment conditions.

Integrative taxonomy of the Ceratozamia mexicana Brongn. (Zamiaceae) species complex from a phylogeographic perspective

Plant Species Biology, EarlyView.
Recent research has ignited a renewed interest in Ceratozamia cycads, unveiling their remarkable diversity. While previous studies primarily focused on morphology, this investigation employs a multidisciplinary approach, integrating phylogenetics, morphology, and ecological niches. Our methods identify seven distinct lineages as separate species.

Comparison of genetic and phenotypic variations in disjunct populations of highly polyploid Betula davurica in the Japanese Archipelago with continental populations in a region of northeast Asia

Plant Species Biology, EarlyView.
Betula davurica is widely distributed in continental regions of northeast Asia but is disjunctly distributed in the Japanese Archipelago. Disjunct Honshu populations are genetically divergent from continental populations in a continuously distributed region in Primorye although disjunct Hokkaido populations are not divergent. These disjunct populations

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

Insect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Multi‐omics reveal the gut microbiota‐mediated severe foraging environment adaption of small wild ruminants in the Three‐River‐Source National Park, China

Integrative Zoology, EarlyView.
This research reveals the gut microbiota‐mediated severe foraging environment adaptation of wild small ruminants in the Three‐River‐Source National Park. Unlike Tibetan sheep (TS), blue sheep (PN and Tibetan antelope (TA) often grazed low‐quality herbage in a wildness environment, and the higher microbial diversity and resilient network characteristics

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO2 vent of Ischia, Italy

Integrative Zoology, EarlyView.
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...
