Effect of N addition on root exudation and associated microbial N transformation under Sibiraea angustata in an alpine shrubland Plant Soil (IF 3.299) Pub Date : 2021-01-15 Wei He, Yuanshuang Yuan, Ziliang Zhang, Juan Xiao, Qing Liu, Raija Laiho, Huajun Yin
Background and aim Root exudates are generally known to play an important role in ecosystem carbon (C) and nitrogen (N) cycling. We aimed to quantify the responses of root exudates to increased N availability in an alpine shrub-dominated ecosystem, and unravel the associated ecological consequences to N cycling. Methods After three consecutive years of N addition at three rates (N0, control; N5, 5

Larger aboveground neighbourhood scales maximise similarity but do not eliminate discrepancies with belowground plant diversity in a Mediterranean shrubland Plant Soil (IF 3.299) Pub Date : 2021-01-15 Angela Illuminati, Jesús López-Angulo, Marcelino de la Cruz, Julia Chacón-Labella, David S. Pescador, Beatriz Pías, Ana M. Sánchez, Adrián Escudero, Silvia Matesanz
Aims An unresolved question in plant ecology is whether diversity of the aboveground and belowground compartments of a plant community is similar at different neighbourhood scales. We investigated how the similarity between both compartments varies with the aboveground sampling grain and if significant discrepancies exist between aboveground and belowground plant diversity at the maximum similarity

Litter and soil characteristics mediate the buffering effect of snow cover on litter decomposition Plant Soil (IF 3.299) Pub Date : 2021-01-15 Sébastien Ibanez, Charles Brun, Annie Millery, Gabin Piton, Lionel Bernard, Jean-Noël Avrillier, Christiane Gallet, Arnaud Foulquier, Jean-Christophe Clément
Aims In cold biomes, snow cover mitigates the harsh winter soil conditions, thereby enhancing overwinter decomposition of organic matter which controls the availability of nutrients for plants and microbial uptake at the beginning of the growing season. Yet, how this buffering effect is modulated by litter traits, soil characteristics and herbivory remains poorly studied. Methods We conducted a litter-bag

Kin bias and male pair-bond status shape male-male relationships in a multilevel primate society Behav. Ecol. Sociobiol. (IF 2.277) Pub Date : 2021-01-15 Federica Dal Pesco, Franziska Trede, Dietmar Zinner, Julia Fischer
Abstract Male-male social relationships in group-living mammals vary from fierce competition to the formation of opportunistic coalitions or the development of long-lasting bonds. We investigated male-male relationships in Guinea baboons (Papio papio), a species characterized by male-male tolerance and affiliation. Guinea baboons live in a multi-level society, with units of one reproductively active
