Globally consistent climate sensitivity of natural disturbances across boreal and temperate forest ecosystems [PDF]

open access: yesEcography, Volume 43, Issue 7, Page 967-978, July 2020., 2020
Disturbance regimes are changing in forests across the world in response to global climate change. Despite the profound impacts of disturbances on ecosystem services and biodiversity, assessments of disturbances at the global scale remain scarce. Here, we analyzed natural disturbances in boreal and temperate forest ecosystems for the period 2001–2014 ...

Co-limitation towards lower latitudes shapes global forest diversity gradients [PDF]

open access: yes, 2022
The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain LDG, but rigorous tests of the ...

Coarse woody debris density and carbon concentration by decay classes in mixed montane wet tropical forests

open access: yesBiotropica, Volume 54, Issue 3, Page 635-644, May 2022., 2022
Wood density and carbon concentration across decay classes of coarse woody debris were estimated for Asian montane tropical mixed forests. Abstract The role of coarse woody debris (CWD) in the global carbon (C) cycle is growing under increasing tree mortality driven by climate variability and disturbances.

Validation of transfer functions predicting Cd and Pb free metal ion activity in soil solution as a function of soil characteristics and reactive metal content. [PDF]

open access: yes, 2007
According to recent insight, the toxicity of metals in soils is better related to the free metal ion (FMI) activity in the soil solution than to the total metal concentration in soil.

Age estimation and body size of the Parsley Frog, Pelodytes caucasicus Boulenger, 1896 from Lake Borçka Karagöl, Turkey [PDF]

open access: yes, 2023
In this study, we described age structure, body size, body mass and the relationships among these parameters for a population of P. caucasicus from Lake Borçka Karagöl, Artvin, Turkey. The mean SVL with standard error was 45.87 mm ± 0.55 (range: 39.98-50.

Threats from urban expansion, agricultural transformation and forest loss on global conservation priority areas [PDF]

open access: yes, 2017
Including threats in spatial conservation prioritization helps identify areas for conservation actions where biodiversity is at imminent risk of extinction. At the global level, an important limitation when identifying spatial priorities for conservation

Farmer Field Schools for Improving Farming Practices and Farmer Outcomes: A Systematic Review

open access: yesCampbell Systematic Reviews, Volume 10, Issue 1, Page i-335, 2014., 2014
This Campbell systematic review examines the effectiveness of farmer field schools in improving intermediate outcomes (such as knowledge and pesticide use) and final outcomes (such as agricultural yields, incomes and empowerment) in low‐ and middle‐income countries (LMICs), as well as implementation factors associated with programme success and failure.
