Extreme drought impacts have been underestimated in grasslands and shrublands globally por Smith, Melinda D., Wilkins, Kate D., Holdrege, Martin C., Wilfahrt, Peter A., Collins, Scott L., Knapp, Alan K., Sala, Osvaldo E., Dukes, Jeffrey S., Phillips, Richard P., Yahdjian, Laura, Peri, Pablo Luis, Zuo, Xiaoan

“…To overcome these problems and better identify the factors that modulate drought responses, we used a coordinated distributed experiment to quantify the impact of short-term drought on grassland and shrubland ecosystems. With a standardized approach, we imposed a single year of drought at 100 sites on six continents. …”

Dynamics of the soil seed bank over the short-term after bush clearing in a semi-arid shrubland in Springbokvlakte thornveld of South Africa por Mndela, M., Madakadze, I.C., Nherera-Chokuda, F., Dube, Sikhalazo

“…The cleared and their adjacent uncleared microsites were marked in the middle of a large shrubland and were protected from grazing. Soil samples were collected at three depths (0–10, > 10–20 and > 20–30 cm) in April (pre-treatment), August, October, December 2016 and, April and August 2017 in bush cleared and uncleared microsites. …”

Postfire nitrogen balance of Mediterranean shrublands: Direct combustion losses versus gaseous and leaching losses from the postfire soil mineral nitrogen flush por Dannenmann, Michael, Díaz Pinés, Eugenio, Kitzler, B., Karhu, K., Tejedor, J., Ambus, P., Parra, A., Sánchez Martin, L., Resco, V., Ramírez, D., Povoas-Guimaraes, L., Willibald, G., Gasche, R., Zechmeister-Boltenstern, S., Kraus, David, Castaldi, S., Vallejo, A., Rubio, A., Rubio, J.M., Butterbach-Bahl, Klaus

“…Here, we quantified both direct C and N combustion losses as well as postfire gaseous losses (N2O, NO and N2) and N leaching after a high‐intensity experimental fire in an old shrubland in central Spain. Combustion losses of C and N were 9.4 Mg C/ha and 129 kg N/ha, respectively, representing 66% and 58% of initial aboveground vegetation and litter stocks. …”

Foraging niche separation of social wasps in an invaded area: Implications for their management por Masciocchi, Maite, Unelius, Carl Rikard, Buteler, Micaela

“…We found that V. germanica wasps prefer to forage at ground level regardless of the resource, while V. vulgaris prefers protein resources at the shrubland level given a choice between a protein bait at ground or at shrubland level. …”

Seasonal variation in mosquito abundance and environmental predictors in semi-pastoral southern Kenya: implications for endemic Rift Valley fever por Gerken, Keli N., Olubowa, Richard R., Chiuya, Tatenda, Korir, Max, Fèvre, Eric M., Stringer, A., Morse, A., Baylis, M.

“…Traps placed at households in cropland areas hosted significantly more mosquitoes overall and were associated with more Anopheles spp., predominantly Anopheles gambiae (Kruskal–Wallis χ2 = 6.9, df = 2, P = 0.03), while those in shrubland areas had more Aedes aegypti (Kruskal–Wallis χ2 = 11.9, df = 2, P = 0.002). …”

Influences of succession and erosion on bird communities in a South American highland wooded landscape por Bellis, Laura Marisa, Pidgeon, Anna Michle, Alcántara, Camilo, Dardanelli, Sebastian, Radeloff, Volker C.

“…Bird communities in Polylepis forests included approximately twice as many species and double the abundance than those in shrublands. Species composition strongly differed between the two growth forms as well, birds that use the ground vegetation to nest and forage were less abundant in shrubland patches, air foragers were also less abundant in shrubland patches. …”
