Field monitoring and genetic diversity of the large copper butterfly Lycaena dispar (Lepidoptera: Lycaenidae)

open access: yesJournal of Biological Research
The large copper butterfly Lycaena dispar (Haworth, 1803) (Lepidoptera: Lycaenidae), which is found across Europe and Asia, has been categorized as a near-threatened species (NT) in South Korea from 2012 mainly due to limited distribution.

Deleting species from model food webs [PDF]

open access: yesarXiv, 2004
We use food webs generated by a model to investigate the effects of deleting species on other species in the web and on the web as a whole. The model incorporates a realistic population dynamics, adaptive foragers and other features which allow for the construction of model webs which resemble empirical food webs.

Modeling Siberian ibex (Capra sibirica) occupancy in Ikh Nart Nature Reserve, Mongolia [PDF]

open access: yes, 2016
As the world becomes increasingly populated, humans continue to modify habitats to suit their needs. Mongolia is one of many Asian countries currently undergoing human-induced landscape change, namely in the form of increased grazing pressure on the land

Suppressing Mo‐Species Leaching in MoOx/A‐Ni3S2 Cathode for Stable Anion Exchange Membrane Water Electrolysis at Industrial‐Scale Current Density

open access: yesAdvanced Science, EarlyView.
This work develops a novel and highly efficient MoS2/Ni3S2 catalyst toward hydrogen evolution reaction (HER) for the anion exchange membrane water electrolyzer. During HER, the MoS2 on the electrode surface undergoes an oxidative dissolution and is redeposited as amorphous MoOx.

Mixed‐Dimensional Floating Gate Phototransistors for Mixed‐Modal In‐Sensor Reservoir Computing

open access: yesAdvanced Science, EarlyView.
Designing bio‐inspired multisensory neuromorphic devices holds significant importance for low‐power and high‐efficiency computing. Here, the authors introduce a floating‐gate phototransistor based on the mixed‐dimensional heterostructure of 0D‐CsPbBr3 QDs and 2D‐MoS2 few layers.

Carbon Hollow Fiber Penetration Electrode with Unsaturated Ni‐N2 Coordination for Enhanced CO2 Electroreduction

open access: yesAdvanced Science, EarlyView.
A hierarchical porous carbon hollow fiber anchoring Ni‐N2 structures is developed as a self‐supporting electrode for efficient and stable CO2 conversion to CO. The unique penetration effect of the hollow fiber electrode, combined with the unsaturated Ni‐N2 coordination structure, significantly enhances CO2 electroreduction performance, achieving high ...

Estimating site occupancy for four threatened mammals in southeastern Laos [PDF]

open access: yes, 2014
textThe tropical forests of Indochina harbor a suite of globally threatened tropical mammal species. These species are difficult to detect, and subsequently understudied. Noninvasive camera trapping was used to survey terrestrial mammals from a protected

Modulating the Evolution of Metastable CaO* for the Near‐Theoretical Performance Breakthrough of Ni/CeO2‐CaO in Integrated CO2 Capture and Methanation

open access: yesAdvanced Science, EarlyView.
A low‐temperature hydrogen spillover decomposition strategy is proposed to reveal the influence of the CaCO3 parent conversion process on the properties of nascent CaO. Under the guidance of the advanced synthesis strategy, the properties of calcium‐based dual‐functional materials are maximally exploited.
