During my research this year, I found a wild strawberry genotype that I tested and found resistance genes to the most aggressive strain in my Neopestalotiopsis collection. The most frequently seen wild species is Fragaria vesca, which has 14 chromosomes and is considered diploid; however, the most economically important plant is F. x ananassa, which is octaploid, harboring 56 chromosomes. It is the result of hybridizing two wild octaploid species (F. virginiana x F. chiloensis); however, there are also tetraploid, hexaploid and decaploid species (Hancock et al., 1991; Hummer et al. 2010).

Are maldanids from deep-sea reduced habitats closely related? Implications of a new wood-fall species of Nicomache from the South China Sea - Frontiers in Marine Science: A new wood-fall-associated maldanid discovered at a depth of 2,321 m in the South China Sea is here morphologically and molecularly described as Nicomache tigilli sp. nov. The new species is characterized as having 21 chaetigers, a prostomium rounded anterior, an arched cephalic keel, anterior ends of nuchal grooves curved outwards, 3–6 acicular spines on chaetigers 1–3, notopodia with simply long and narrow capillary chaetae, and an anal funnel with triangular, unequal-sized anal cirri. Our molecular analyses of the genus Nicomache, encompassing COI, 16S, 18S, and 28S genes support establishing the new species, which appear phylogenetically closely related to the other species of the genus from reduced habitats.

New study sheds light on the lasting impact of fire on soil in North-East Mediterranean ecosystems. Burned areas show significant changes in chemical and physical properties, with distinct effects on different plant communities. https://lnkd.in/dEv6SKTq #FireEcology #SoilHealth

In a testament to my tenacity and wonderful support system, the final chapter of my dissertation was published! We used members of the Jewelflower species with varying affinity to serpentine soils to characterize the rhizoplane (a subset of the rhizosphere) and observed conserved shifts of the associated bacterial community in response to water stress. https://lnkd.in/g3S9yxhZ

Bacteriophages (phages) rely on bacterial-feeding nematodes for transport in soil, showing that nematodes can carry phages through complex habitats. The study found that nematodes can transport phages externally or internally without the need for host bacteria. This discovery enhances our understanding of virus transmission in soil and reveals new interactions that impact soil ecosystems. https://buff.ly/3YzVfSK

Definition of: Community, Population, Ecosystem and Biosphere The biosphere is the zone of air, land and water where organisms exist. It is commonly known as the global sum of all ecosystems and consists of several layers including the atmosphere, the lithosphere and the hydrosphere. Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community. Ecosystem is system that includes all living organisms (biotic factors) in an area as well as its physical environment (abiotic factors) functioning together as a unit. Supplement. An ecosystem is made up of plants, animals, microorganisms, soil, rocks, minerals, water sources and the local atmosphere interacting with one another . The biosphere is the zone of air, land and water where organisms exist. It is commonly known as the global sum of all ecosystems and consists of several layers including the atmosphere, the lithosphere and the hydrosphere.
