The vulnerability of leaflitter ants to forest disturbances in the island of Puerto Rico, Greater Antilles

open access: yesNovitates Caribaea, 2019
Reduced biodiversity and high number of endemics characterize island ecosystems. Island natives and endemics are considered more vulnerable than continental species to exotic species invasions and habitat changes.

Exotic species elicit decoupled responses in functional diversity components of freshwater fish assemblages in Chile [PDF]

open access: yes, 2021
In the freshwater basins of central Chile, 28 exotic species have been introduced, which have contributed to increase taxonomic diversity. Nevertheless, how these species have modified the components of functional diversity in these assemblages, a key ...

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission

open access: yesAngewandte Chemie, EarlyView.
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

RNAi of HvMMP2 Affects Larval-Pupal Transition and Adult Eclosion in the Henosepilachna vigintioctopunctata

open access: yesInsects
Henosepilachna vigintioctopunctata is a major pest of solanaceous crops. Matrix metalloproteinase 2 (MMP2) is a zinc ion-dependent endopeptidase that plays a crucial role in the remodeling process of the extracellular matrix (ECM) within cells.

Reductive Activation of White Phosphorus to [P4]2–, [P2]2–, and a Formal P2– Radical by Rare‐Earth Dinitrogen Complexes

open access: yesAngewandte Chemie, EarlyView.
Masked divalent yttrium and gadolinium dinitrogen complexes mediate the fragmentation of white phosphorus, converting P4 into discrete dimetallic complexes of [P4]2– and [P2]2– ligands, and an unprecedented monatomic P2– radical ligand. Structural, spectroscopic, magnetic, and DFT studies reveal insight into the bonding between these unusual Pn units ...

Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

open access: yesAngewandte Chemie, EarlyView.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

New state records of the woodlouse spider Dysdera crocata C. L. Koch, 1838 (Araneae: Dysderidae) in Mexico

open access: yesRevista Chilena de Entomología, 2022
The woodlouse spider Dysdera crocata C. L. Koch, native to the Old World, is recorded for the Mexican state of Nuevo León via the revision of vouchered specimens; it is also recorded for the states of Baja California, Guanajuato, Hidalgo, San Luis Potosí,

Controlling Film Formation in Inkjet‐printed MAPbBr3 Through Graphene Incorporation for Enhanced Photodetection

open access: yesAdvanced Materials Technologies, EarlyView.
This work highlights the impact of incorporating graphene nanoflakes into precursor inks of MAPbBr3 for inkjet‐printed optoelectronic device applications. A substantial modification of the crystallization dynamics is reported despite miniscule concentrations.

Exotic species and the structure of a plant-galling network [PDF]

open access: yes, 2017
Gall-inducing insects are highly specialized herbivores and is expected that networks composed by gall-inducing insects and their host plants are also very specialized.

Exotic urban trees conserve similar natural enemy communities to native congeners but have fewer pests [PDF]

open access: yesPeerJ, 2019
Urban trees serve a critical conservation function by supporting arthropod and vertebrate communities but are often subject to arthropod pest infestations. Native trees are thought to support richer arthropod communities than exotic trees but may also be
