Data from: The Automated Root Exudate System (ARES): a method to apply solutes at regular intervals to soils in the field

1) Root exudation is a key component of nutrient and carbon dynamics in terrestrial ecosystems. Exudation rates vary widely by plant species and environmental conditions but our understanding of how root exudates affect soil functioning is incomplete, in part because there are few viable methods to manipulate root exudates in situ. To address this, we devised the Automated Root Exudate System (ARES), which simulates increased root exudation by applying small amounts of labile solutes at...

Data from: Tree functional diversity affects litter decomposition and arthropod community composition in a tropical forest

Benita C. Laird-Hopkins, Laëtitia M. Bréchet, Biancolini C. Trujillo & Emma J. Sayer
Disturbance can alter tree species and functional diversity in tropical forests, which in turn could affect carbon and nutrient cycling via the decomposition of plant litter. However, the influence of tropical tree diversity on forest floor organisms and the processes they mediate are far from clear. We investigated the influence of different litter mixtures on arthropod communities and decomposition processes in a 60-year-old lowland tropical forest in Panama, Central America. We used litter mixtures representing...

Data from: Mauritius on fire: tracking historical human impacts on biodiversity loss

Fire was rare on Mauritius prior to human arrival (AD 1598); subsequently three phases of elevated fire activity occurred: c. 1630-1747, 1787-1833, and 1950-modern. Elevated fire frequency coincided with periods of high human impact evidenced from the historical record, and is linked to the extinction of island endemics.

Data from: Tropical forest restoration: fast resilience of plant biomass contrasts with slow recovery of stable soil C stocks

Faming Wang, Yongzhen Ding, Emma Sayer, Qinlu Li, Bi Zou, Qifeng Mo, Yingwen Li, Xiaoliang Lu, Jianwu Tang, Weixing Zhu, Zhian Li & Emma J. Sayer
1. Due to intensifying human disturbance, over half of the world’s tropical forests are reforested or afforested secondary forests or plantations. Understanding the resilience of carbon (C) stocks in these forests, and estimating the extent to which they can provide equivalent carbon (C) sequestration and stabilization to the old growth forest they replace, is critical for the global C balance. 2. In this study, we combined estimates of biomass C stocks with a detailed assessment...

Data from: Escitalopram and NHT normalized stress-induced anhedonia and molecular neuroadaptations in a mouse model of depression

Anhedonia is defined as a diminished ability to obtain pleasure from otherwise positive stimuli. Anxiety and mood disorders have been previously associated with dysregulation of the reward system, with anhedonia as a core element of major depressive disorder (MDD). The aim of the present study was to investigate whether stress-induced anhedonia could be prevented by treatments with escitalopram or novel herbal treatment (NHT) in an animal model of depression. Unpredictable chronic mild stress (UCMS) was...

Data from: The sentinel behaviour of Arabian babbler floaters

Roni Ostreiher & Aviad Heifetz
The sentinel behaviour of 38 Arabian babbler adult floaters, who lived alone within a territory belonging to a foreign group, was studied and compared with their own sentinel behaviour in the past, when they were group members. All floaters acted as sentinels and uttered ‘alarm calls’. This suggests that sentinel activity is due at least, in part, to selfish motives. Floaters sentinelled less than they did as group members, with the decrease in sentinel activity...

Data from: Does functional soil microbial diversity contribute to explain within-site plant β-diversity in an alpine grassland and a dehesa meadow in Spain?

Yoseph N. Araya, Maik Bartelheimer, Cipriano J. Valle, Rosa M. Crujeiras & Gonzalo García-Baquero
Questions Once effects of hydrological and chemical soil properties have been accounted for, does soil microbial diversity contribute to explain change in plant community structure (i.e. within-site β-diversity)? If so, at what spatial scale does microbial diversity operate? Location La Mina in Moscosa Farm, Salamanca, western Spain (dehesa community) and Laguna Larga in the Urbión Peaks, Soria, central-northern Spain (alpine grassland). Methods The abundance of vascular plant species, soil Gram-negative microbial functional types and soil...

Data from: Shoot growth of woody trees and shrubs is predicted by maximum plant height and associated traits

Sean M. Gleason, Andrea E.A. Stephens, Wade C. Tozer, Chris J. Blackman, Don W. Butler, Yvonne Chang, Alicia M. Cook, Julia Cooke, Claire A. Laws, Julieta A. Rosell, Stephanie A. Stuart, Mark Westoby & Andrea E. A. Stephens
1. The rate of elongation and thickening of individual branches (shoots) varies across plant species. This variation is important for the outcome of competition and other plant-plant interactions. Here we compared rates of shoot growth across 44 species from tropical, warm temperate, and cool temperate forests of eastern Australia. 2. Shoot growth rate was found to correlate with a suite of traits including the potential height of the species, xylem-specific conductivity, leaf size, leaf area...
