A total of 103 specimens of Hoplias intermedius (Günther, 1864) and 86 specimens of H. malabaricus (Bloch, 1794) from the upper São Francisco River, State of Minas Gerais were collected between April 2011 and August 20...

Abstract This study used information about Procamallanus (Spirocamallanus) inopinatus Travassos, Artigas & Pereira, 1928 that had been published over a period of more than 90 years to investigate the infection and distri...

Identifying the determinants of tree species composition among contrasting altitudinal tropical forest types will improve our understanding of the main factors and processes controlling tree species' distributions and pa...

Annonaceae is a pantropical plant family that is an important component in Neotropical forests, yet its diversity, distribution and conservation status in Mexico has not been comprehensively synthesized. This study provi...

Se presentan los resultados del análisis de los restos faunísticos recuperados en el sitio arqueológico Los Conitos (valle de Potrerillos, Mendoza, Argentina). El sitio posee dataciones absolutas que definen las ocupa...

Drepanopus forcipatus and Calanus australis are key planktonic copepods on the southern Patagonian shelf. Their feeding and reproductive patterns and population status were investigated during late summer, when environme...

Abstract More than 1.450 marine fish species are commercialized as ornamental fish and approximately 90% of these are wild-caught. Rainford's butterflyfish, Chaetodon rainfordi (McCulloch, 1923), is endemic to the wester...

Abstract Conservation of long-lived marine species depends on understanding how individuals use habitats as they grow. Yet management often relies on size- or place-based stage classifications that overlook behavioral pl...

CO2/H2-mediated toluene methylation over metal oxide–zeolite bifunctional catalyst offers a sustainable route for para-xylene (PX) synthesis, yet how zeolite morphology and acidity synergistically govern this coupled p...

Context. Many low-redshift active galactic nuclei harbor a supermassive black hole accreting matter at low or medium rates. At such rates, the accretion flow usually consists of a cold optically thick disk, plus a hot, l...

The rodent Oligoryzomys longicaudatus (Bennett, 1832) (Rodentia, Cricetidae) inhabits southern forests of Argentina and Chile, a region severely affected by glaciations during the Pleistocene-Holocene periods. We evaluat...

Drosophila koepferae and Drosophila buzzatii are closely related cactophilic species with overlapping distributions in Andean regions. Both species exploit necrotic tissues, and whereas the former breeds and feeds mostly...

The study reports photographic evidence of range extension for three avian species: Western Tragopan Tragopan melanocephalus (Gray, 1829), Tibetan Snowcock Tetraogallus tibetanus (Gould, 1854), and Tibetan Sandgrouse Syr...

Using single-shot velocity map imaging technique, explosion imaging of different ion species ejected from 50 nm SiO2 nanoparticles are obtained excitedly by strong near-infrared and ultraviolet femtosecond laser fields....

Monitoring species abundance and distribution is a prerequisite when assessing species status and population viability, a difficult task to achieve for large herbivores at ecologically meaningful scales. Co-occurrence pa...

Formaldehyde (HCHO) is a ubiquitous atmospheric constituent, originating from primary emissions (natural and anthropogenic) and secondary production via the oxidation of volatile organic compounds (VOCs). In addition to ...

Abstract The unambiguous identification of individual chromosomes is fundamental to studying genome organisation and evolution. Sheepgrass (Leymus chinensis (Trin.) Tzvel), a perennial tetraploid grass closely related to...

La historia geológica y climática del noroeste Argentino presenta fuertes cambios producto de los constantes procesos orogénicos y climáticos ocurridos durante el Neógeno y períodos glaciares e interglaciares del C...
