(Taylor & Francis, 2020)The understanding of closed-shell interactions has become of tremendous relevance in the ever-growing field of supramolecular chemistry. Here, we present a theoretical study in which we characterised the intermolecular ...
-
(Elsevier, 2020)This review deals with the problem of designing safer solvents for chemical transformation and chemical processes. These materials generically defined as neoteric solvents include the well known ionic liquids (ILs) and ...
-
(American Physical Society, 2020)The existence of nonvanishing Bohm potentials, in the Madelung-Bohm version of the Schrodinger equation, allows for the construction of particular solutions for states of quantum particles interacting with nontrivial ...
-
(Nature, 2020)The southern coastline of South America is a remarkable area to evaluate how Quaternary glacial processes impacted the demography of the near-shore marine biota. Here we present new phylogeographic analyses in the pulmonate ...
-
(Wiley-VCH Verlag, 2019)Atrazine is a pesticide used to control broadleaf weeds, however its wide distribution and its high persistence in the soil and in surface waters has resulted in a public and environmental health problem. Present results ...
-
(Natl Inst R&D Materials Physics, 2020)CuIrSnS4, CuIrSnSe4 and CuIrSnS2Se2 were synthetized by a solid-state reaction at 700 degrees C. Powder X-ray diffraction patterns were consistent with normal spinel-type structure. Scanning electron microscopy (SEM-EDS) ...
-
(Taylor and Francis, 2020)Gomortega keuleis an endangered tree species, the single extant species of a monotypic family. It is safeguarded only in one protected area. Its recruitment and germination are low, possibly in part because rodents prey ...
-
(Springer Netherlands, 2019)Land has traditionally been spared to protect biodiversity; however, this approach has not succeeded by itself and requires a complementary strategy in human-dominated landscapes: land-sharing. Human–wildlife conflicts are ...
-
(American Chemical Society, 2020)Reduction of carbonyl moieties to the corresponding alcohol using simply hydrazine hydrate has been considerably unfeasible until now due to the well-known condensation reaction. However, herein, we report that using an ...
-
(Springer, 2021)The lack of winter cold is a severe limitation for the cultivation of grapevines (Vitis vinifera L) in areas with warm winter climates. This phenomenon is currently becoming quite important due to global warming, which ...
-
(American Geophysical Union, 2020)Sea surface temperature (SST) is used to infer past changes in the state of the climate system. Here we use a combination of newly generated and published organic paleothermometer records, together with novel high-resolution ...
-
(MS Editions, 2020)Triatoma infestans (Klug) is the principal vector of Chagas disease in Bolivia and neighboring countries. The objective of this study was to determine the chemical composition of the EO of the Chilean laurel, Laurelia ...
-
(Springer, 2020)Alchisme grossa is a treehopper species showing maternal care until at least the third nymphal instar. A secondary female treehopper has frequently been observed near a family (primary female guarding its egg clutch). ...
-
(Taylor & Francis, 2020)Larvae of Leptus hringuri parasitizing families (adult female + offspring) of the treehopper Alchisme grossa on two host-plants, Brugmansia suaveolens (BS) and Solanum ursinum (SU), were studied. The effect of microenvironmental ...
-
(Allen Press, 2020)Understanding animals' daily activity patterns such as foraging and resting is key to the effective conservation of individuals, populations, and species. Expanding habitat usage by humans today is likely one of the major ...
-
(Geoscienceworld, 2020)New detrital zircon U-Pb geochronology data from the Cenozoic Magallanes-Austral Basin in Argentina and Chile similar to 51 degrees S establish a revised chronostratigraphy of Paleocene-Miocene foreland synorogenic strata ...
-
(Springer, 2017-06)Nomadic pastoralism and transhumance are ancient human adaptations to the movements of large herbivores, which themselves migrate to follow favorable environmental conditions. Free-ranging livestock production has been ...
-
(Universidad de Concepción, Chile, 2020)Ripartites tricholoma collected in the Nature Reserve Altos de Cantillana, near Santiago is described as a first record of this fungal genus and species for Chile. This is a contribution to the knowledge of fungal diversity ...
-
(PEERJ, 2020)Carotenoids are essential components of the photosynthetic antenna and reaction center complexes, being also responsible for antioxidant defense, coloration, and many other functions in multiple plant tissues. In tomato, ...
-
(Elsevier, 2020)Point counts are widely used to assess bird diversity. However, this method has some limitations and can be affected by observer bias. For this reason, it is commonly complemented with other methods (e.g., mist-nets, sound ...
