The ongoing biodiversity disappearance on islands worldwide is alarming. Without an accurate biodiversity assessment, it is impossible to stop the loss of the world’s islands irreplaceable natural heritage. To assess b...

A catadioptric lens structure, also known as pancake lens, has been widely used in virtual reality (VR) displays to reduce the formfactor. However, the utilization of a half mirror (HM) to fold the optical path thrice le...

Some arguments currently used to support breed conservation are examined. The central point is that we cannot conserve all breeds because we do not have financial resources enough to keep everything (mainly in developing...

The current-voltage characteristics of a thin long platinum wire in air with acetone or ethanol small admixtures were obtained. Using the quadratic dependence of platinum resistance on temperature, the temperature-curren...

Abstract The Eocene–Oligocene transition was the crucial turning point when Earth’s climate shifted to its current icehouse state. Understanding how the marine biosphere responded during this transition is not well-c...

Few-mode and multi-core fibers are proposed and demonstrated for contactless vital signs monitoring in this paper. In-line optical fiber interferometers using few-mode and multi-core fibers are designed and offset splici...

Octodontoidea is the most species-rich cladeamong hystricomorph rodents. Based on a combined parsimonyanalysis of morphological and molecular data of extinctand extant species, we analyze the history of SouthAmerican oct...

Creativity and innovation in ludruk need to be done because this traditional art is already on the verge of extinction. The lack of regeneration of interested young people and changes in people's tastes are the dominant ...

ABSTRACT For different dyes like methyl green, methyl orange, methyl red, malachite green, crystal violate, safranin, and methylene blue. We calculated their optical constants like wavelengths of maximum absorption, mol...

Intense training refers to training mediated by emotionally arousing experiences, such as aversive conditioning motivated by relatively high intensities of foot-shock, which produces a strong memory that is highly resist...

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...

Recent studies of the Middle and Upper Paleolithic in the northwestern Caucasus are focused on the research of relations between natural (climate and environment) and social (behavior and adaptations) factors that govern...

El Carpinterito Ocráceo (Picumnus nebulosus) se considera cercano a la amenaza en el orden internacional y amenazado en Argentina. En Argentina cuenta con pocos registros en las riberas del río Uruguay, en el extremo n...

The new charge-transfer complexes (CT) of eleven Schiff1 bases molecules as n-electron donors with the acceptor 1,4-naphthoquinone were studied spectrophotometrically in chloroform solution. The physical constants (a,b,C...

ABSTRACT Amphibians are excellent bioindicators because they are sensitive to chemical pollution and can indicate ecosystem changes due to the presence of or exposure to chemical compounds. Here we report evidence of the...

Anthropogenic climate change is one of the main threats to global biodiversity, with amphibians being among the most vulnerable vertebrate groups. In this context, the IUCN currently lists 69 species of Neotropical glass...

Through phylogenetic reconstruction this work analyzes the diversification of lanceolate points of the South Central Andes which began in the early Holocene and spanned the entire mid- Holocene. Based on a regional-scale...

Plants constitute the foundation of life on Earth, providing oxygen, food, and ecosystem services essential for human well-being. At the same time, they are among the most threatened components of biodiversity, with curr...

apria himalayana Griff. f. albovinosa Banziger & Hansen (Rafflesiaceae) is rare and endemic to northeastern Thailand, Vietnam, and Manipur, with a short flowering season ranging from late October to late November, due to...

Not all species are likely to be equally affected by habitat fragmentation; thus, we evaluated theeffects of size of forest remnants on trophically linked communities of plants, leaf-mining insects, and theirparasitoids....

As the key element for optical systems, polarization controllers with versatile functionalities are highly desired. Here, a CMOS-compatible polarization switch is proposed and realized by using a Mach–Zehnder interfero...

We compiled and analysed 16 historical photographic records of the Jaguar Panthera onca in the state of Santa Catarina before 1985, most of which have not been published in scientific literature. These records obtained f...

The Beijing–Tianjin–Hebei region of China features a unique topographic structure. Influenced by synoptic-scale systems, the region’s atmospheric strata over the plains are distinct. This study utilizes ground aero...

Rapid climatic changes and increasing human influence at high elevations around the world will have profound impacts on mountain biodiversity. However, forecasts from statistical models (e.g. species distribution models)...
