Effects of clouds on the radiative heat exchange in the atmosphere.

Geofísica Internacional, 1975
Las nubes son los principales reguladores del flujo radiativo. A su vez las nubes mismas están sujetas a efectos directos e indirectos de la radiación. Los efectos directos se producen mediante absorción y emisión de radiación por las nubes.

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

It is cool to be clear: Transparency induces a thermal cost in clearwing butterflies

Functional Ecology, Volume 39, Issue 9, Page 2452-2464, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In butterflies, wing transparency raises the question of potential costs for vital functions, such as thermoregulation. The thermal melanism hypothesis posits that darker colorations enable higher absorption of solar radiation, leading to the prediction that such ...

Spatiotemporal Dynamics of Non‐Ecological Speciation in Rubyspot Damselflies (Hetaerina spp.)

Molecular Ecology, Volume 34, Issue 12, June 2025.
ABSTRACT Non‐ecological speciation is a common mode of speciation, which occurs when allopatric lineages diverge in the absence of pronounced ecological differences. Yet, relative to other speciation mechanisms, non‐ecological speciation remains understudied.

Latitudinal variation rate of geomagnetic cutoff rigidity in the active Chilean convergent margin [PDF]

Annales Geophysicae, 2018
We present a different view of secular variation of the Earth's magnetic field, through the variations in the threshold rigidity known as the variation rate of geomagnetic cutoff rigidity (VRc).

Ultraviolet radiation protection factors of livestock shade cloths for free‐range pigs

Veterinary Dermatology, Volume 35, Issue 6, Page 641-651, December 2024.
Background – Protection from solar ultraviolet radiation (UVR) is paramount in light‐skinned pig breeds such as Yorkshire or Landrace to avoid sunburn. Objectives – Determination of the UVR exposure of a pig and the sun protection abilities of shade cloths with different shade rates.

IRRADIACIÓN SIMULTANEA DE CAMPOS CONTIGUOS CON HACES DE FOTONES

Anales (Asociación Física Argentina), 2013
Se analiza la uniformidad de dosis en todo el volumen de tratamiento cuando éste se irradia con un haz de fotones único o con haces contiguos. Los parámetros considerados son: energía del haz, distancia-fuente-superficie, tamaño del campo, incidencia ...

Meristic co‐evolution and genomic co‐localization of lateral line scales and vertebrae in Central American cichlid fishes

Ecology and Evolution, Volume 14, Issue 9, September 2024.
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...

Strong phylogenetic signal and models of trait evolution evidence phylogenetic niche conservatism for seagrasses

Journal of Ecology, Volume 112, Issue 3, Page 446-460, March 2024.
Our study highlights the relevance of evolution from common ancestors and shared history underpinning large seagrass phylogenetic structuring. Abstract Phylogenetic signal (PS) is the propensity of closely related species to resemble each other. PS has been tested across clades of terrestrial plants; however, insight for seagrasses is still lacking ...
