The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

SREQP: A Solar Radiation Extraction and Query Platform for the Production and Consumption of Linked Data from Weather Stations Sensors

Journal of Sensors, Volume 2016, Issue 1, 2016., 2016
Nowadays, solar radiation information is provided from sensors installed in different geographic locations and platforms of meteorological agencies. However, common formats such as PDF files and HTML documents to provide solar radiation information do not offer semantics in their content, and they may pose problems to integrate and fuse data from ...

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

Efecto de la radiación ultravioleta sobre los ecosistemas acuáticos [PDF]

, 1998
Hasta hace poco tiempo se consideraba que la radiación ultravioleta carecía de importancia como factor ambiental en los ecosistemas acuáticos, ya que se suponía que se absorbía totalmente en los primeros centímetros de la columna de agua.

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.
