    #Sicklealfalfa #Medicago sativa L.subsp. #falcata is considered a #subspecies of lucerne, but is sometimes also seen as own #species of the M. sativa-#complex. It is native to #Eurasia and prefers deep, lime-rich #soils, here on Mount #Teufelsberg #Berlin with #Chorthippus cf.#mollis. K. Kaljund & V. Jaaska (2010) found a high genetic #diversity even in smaller #isolatedpopulations due to plant's biology, i.a.#autotetraploidy.

    Below a #grasshopper nymph of the #Chorthippus #biguttulus #group, including closely related European #species C. biguttulus, C. brunneus, and C. mollis. They cannot be clearly differed #morphologically, only by their #songs. B. Gottsberger & F. Mayer (2019) studied mechanisms of #speciesboundarystabilization between C. brunneus/C. biguttulus, which can #hybridize. But hybrids exhibit #songpreferences of C. biguttulus females.
