  1. The common #daisy, #Bellis #perennis (#Asteraceae), was originally native to the #Mediterranean region, Western Asia, and North Africa. It arrived in Central Europe through early human activity and is therefore named an #archaeophyte. A. Rathore et al. (2024) identified two #begomoviruses from it for the first time using PCR and full-length DNA analysis.

  2. The #microbial #diversity of #dynamic #ecosystems can today be assessed using more efficient methods. M. F. Peña-Valencia et al. (2026) identified potential #polyethyleneterephthalate (#PET)-degrading #enzymes from #mangrove #soil using #AI, #3D #structuralanalysis and #metagenomics. Some of these enzymes could be assigned to the bacterial genus #Microbulbifer.

  3. Common #ivy #Hedera #helix (#Araliaceae) exhibits either a #creeping or #climbing #stem, named stem #dimorphism, as well as different leaf shapes (#heterophylly). The #species is #native to western, central, and southern #Europe, extending as far as Sweden and Turkey. Elsewhere it appears as #neophyte. Its evolutionary roots lie in Tertiary tropical forests.

  13. @setiinstitute A great total view towards Europa is visible here.#Jupiter's #moon is subject to multiple #scientificinterests. One of them is represented by the NASA #EuropaClipper #Mission that launched in October 14, 2024. The #spaceprobe has different purposes. Besides the superficial ice crust it i.a. collects information about the #subsurface #ocean. Europa is one candidate for possible #extraterrestriallife.

  14. The #fumewort #Corydalis #solida (#Papaveraceae) grows to a height of 10 to 20 cm and blooms in #CentralEurope from April to May. The species is widespread throughout #Eurasia and is characterized i.a by a particularly #firm root #tuber. M. Kılıc et al. (2019) describe the in vitro #anticholinesteraseactivity and "fractions from tubers with #neuroprotectivepotential".

It is distributed from the #NicobarIslands to New Guinea, migrates in orderly flocks between islands, often is a #grounddweller, but breeds in #treenests. N. Alexandre et al.

  20. RE: flipboard.com/@sciencealert/sc

    Unlike #Earth, our #moon is subjected to a constant #bombardment by #meteorites of all sizes, due in part to the lack of a comparable #atmosphere. However, it is rare for larger craters to be discovered immediately after an #impact. Thanks to NASA's #LunarReconnaissanceOrbiter Camera, a larger impact in late spring 2024 could be described in more detail.

  21. The London #plane (#Platanus × #hispanica) is frequently planted in major German cities due to its tolerance of urban climates, as seen here in park Rehberge, Berlin. Photos show the #fruit, a spherical cluster of nut-like achenes with wind dispersal. According to S. Zhang et al. (2019), three #FULlike #genes, PlacFL1/2/3, regulate flowering, #flowerdevelopment, and #dormancy.

  34. Lichens indicate airquality and climateconditions. I found the #species below in #Jungfernheide #forest #Berlin. While #Parmelia #sulcata requires light, but is flexible, #Hypotrachyna #afrorevoluta needs warm, nitrogen-poor #environments and clean air. The latter is rareer in #Germany, but spreading eastward based on #globalwarming. D. Masson (2004) found it on #treetrunks and #branches.

  35. RE: mastodon.green/@plazi_species/

    #Endemic #species are always interesting from different perspectives, e.g. from an #evolutionary and #ecological point of view. This also applies to #skinks of the genus
    #Madascincus, being with several known species endemic to #Madagascar.
    A. Miralles et al. (2026) described based on #multilocus #phylogenetics and #morphology two #newspecies:
    M. #irery and M.
    #minotaurus, with restricted distributions to limited areas of Madagascar only.

  36. #Freshwater #lakes,like #Flughafensee #Berlin, play a complex #role in #globalwarming. Their #sediments are important #carbonsinks. However, they also release #CO2/#methane through microorganism activities. Furthermore, #lakeswarmup faster than surrounding air. L. Huang et al.(2024) address this and predict #shifts in #aquaticspecies #distributions and rearrangements of #freshwaterhabitats.

  37. RE: fediscience.org/@PLOSBiology/1

    Close #relationships, e.g. cryptic species complexes, can lead to species being almost indistinguishable from one another. However, close relationships can also lead to #distinct #differences, as K. Tomihara et al. (2026) investigated at the molecular genetic level in the sister species of #silkmoths #Bombyx #mori and #Bombyx #mandarina. According to their findings, a conserved #Wnt family #genecluster is of particular importance, being associated with #morphologicaldivergence.

    About the #nuclear #porecomplex (#NPC) #protein #Nup107 regulating broader #neuroendocrine functions in #fly larval #brains. The authors J. Kawadkar et al. (2026) in experiments reduced the Nup107 protein that enables #moleculetransfer between nucleus and cellular cytoplasma in #fruitflies using suitable genetic tools. According to the authors, there is a wider context between the protein and larval #developmentalprocesses based on the #steroidhormone #ecdysone.
