A global assessment of animal community responses to agricultural management. [PDF]

Conserv Biol
Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

Growth and resilience responses of Scots pine to extreme droughts across Europe depend on predrought growth conditions. [PDF]

Glob Chang Biol, 2020
We examined tree growth resilience of Scots pine along a 2,800 km latitudinal gradient from southern Spain to north‐eastern Germany using 615 adult trees from 30 different sites. We found that the resilience of Scots pine to extreme drought decreased in mid‐elevation and low productivity sites from 1980–1999 to 2000–2011 due to more frequent and severe

Seedling Emergence and Phenotypic Response of Common Bean Germplasm to Different Temperatures under Controlled Conditions and in Open Field [PDF]

Frontiers in Plant Science, 2016
Rapid and uniform seed germination and seedling emergence under diverse environmental conditions is a desirable characteristic for crops. Common bean genotypes (Phaseolus vulgaris L.) differ in their low temperature tolerance regarding growth and yield ...

Criteria for use and conservation of trees in pastures based on farmers’ local knowledge in a tropical dry forest zone in Colombia

Tropical Grasslands-Forrajes Tropicales, 2021
Trees are attributed an important role in livestock farms, fulfilling various functions. The study documents the retention of woody species in cattle farms from local and technical knowledge in the upper part of the Magdalena river basin, Colombia.

From the ground up: Patterns and perceptions of herbaceous diversity in organic coffee agroecosystems

Ecological Solutions and Evidence, Volume 3, Issue 3, July–September 2022., 2022
Smallholder farms that transition to organic and biodiverse production are increasingly recognized as strongholds of agrobiodiversity. Yet the emergent herbaceous communities in these organic systems remain understudied, with the functional diversity and management of this stratum relatively unknown.

Is the Impact of Ethylammonium Nitrate on Soil Basal Respiration Modified by Addition of Aluminium Salt to Improve the Performance in Electrochemical Applications?

Chemistry Proceedings, 2021
Interest in the possible use of EAN in electronic devices has increased in recent years. EAN can be used directly as an electrolyte, but its application could potentially be optimized by mixing with a metal salt such as Al(NO3)3.

Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores

Ecological Solutions and Evidence, Volume 3, Issue 2, April–June 2022., 2022
Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the
