Integrating remote‐sensing and meteorological data to identify key drivers of the potential distribution of a grassland grasshopper

open access: yesEcological Entomology, EarlyView.
An ensemble model achieved excellent accuracy (AUC = 0.973) in predicting the potential distribution of O. decorus asiaticus. Climate (temperature & August precipitation) and vegetation type are the primary drivers defining the species' suitable habitats.

Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

open access: yesJournal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

Population and herbarium genomics provide a comprehensive framework for a revision of Microcoleus (Cyanobacteria)

open access: yesJournal of Phycology, EarlyView.
Abstract Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts—complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset.

Strategies for Legitimizing Regeneration in Supply Chain Fields

open access: yesJournal of Supply Chain Management, EarlyView.
ABSTRACT In view of escalating environmental degradation, regenerative business has been proposed to restore social–ecological systems. However, as regeneration fundamentally departs from mainstream approaches and lacks commonly accepted standards, it suffers from a liability of newness that hampers its broader legitimation and adoption.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

open access: yesNew Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Spatial and temporal variability of CO2 emisions in soils under conventional tillage and no-till farming [PDF]

open access: yes, 2012
Agricultural soils can act as a carbon sink depending on the soil management practices employed. As a result of this functional duality, soil management systems are present in international documents relating to climate change mitigation.
