In: Weed Research, 2021, vol. 61, no. 1, p. 1-12

Endozoochory is known as an important mechanism for the spread of weeds. We carried out experiments to assess the fate of seeds of several weed species (Convolvulus arvensis, Cuscuta campestris, Rumex crispus, Hordeum spontaneum and Sorghum halepense) after passing through the gut of sheep and goat. Eighteen animals of both sheep and goat received diet mixed with seeds of the weed species or ...

Draft genome sequence of the virulent Clostridium chauvoei reference strain JF4335

Falquet, Laurent ; Calderon-Copete, Sandra P. ; Frey, Joachim

In: Genome Announcements, 2013, vol. 1, no. 4, p. -

Clostridium chauvoei is the etiological agent of blackleg, a disease of cattle and sheep with high mortality rates, causing severe economic losses in livestock production. Here, we report the draft genome sequence of the virulent C. chauvoei strain JF4335 (2.8 Mbp and 28% G+C content) and the annotation of the genome.

Multi-decadal mass balance series of three Kyrgyz glaciers inferred from modelling constrained with repeated snow line observations

Barandun, Martina ; Huss, Matthias ; Usubaliev, Ryskul ; Azisov, Erlan ; Berthier, Etienne ; Kääb, Andreas ; Bolch, Tobias ; Hoelzle, Martin

In: The Cryosphere, 2018, vol. 12, no. 6, p. 1899–1919

Glacier surface mass balance observations in the Tien Shan and Pamir are relatively sparse and often discontinuous. Nevertheless, glaciers are one of the most important components of the high-mountain cryosphere in the region as they strongly influence water availability in the arid, continental and intensely populated downstream areas. This study provides reliable and continuous surface mass...
