Species of Lobophora (Dictyotales) are distributed throughout the subtropical and tropical seas worldwide. Recent analyses have revealed high species diversity in regions previously presumed to host only a single species, such as the Bismarck Sea, Eastern Pacific, Western Atlantic, Mediterranean Sea, and Greater Caribbean. Here, samples from Veracr...

Seaweed has a variety or biological activities, including antibacterial, antioxidant, antidiabetic, and anti-inflammatory ones. Mexico has great macroalgae diversity, with nearly 1700 species; therefore, in this research two seaweeds from Mexico, Sargassum buxifolium and Padina gymnospora, were investigated for their antibacterial, antidiabetic, an...

Fortalecer el sistema de monitoreo marino para el apoyo de la toma de decisiones y la aplicación de las políticas públicas para los mares mexicanos, la pesca sustentable y la conectividad ecológica y el manejo integrado del paisaje marino.

The endemic Cladophoraceae of Lake Baikal are a group with high species richness, monophyly, and apparently recent speciation, making them ideal for the study of the genetic structure of an alga in this large freshwater environment. We analysed the population genetics of Chaetomorpha (= Ch.) moniliformis, Cladophora (= Cl.) compacta and Cl. kursano...

Ancient lakes are centres of biological diversification that hold many examples of adaptive radiation and species flocks. The recently discovered species flock of Cladophoraceae in Lake Baikal is a group of green algae that exhibit low genetic divergence in ribosomal markers (LSU, SSU, and ITS), but wide morphological differentiation. Microsatellit...

Ancient lakes are centres of adaptive radiation and speciation. The Cladophoraceae endemic to ancient Lake Baikal is a morphologically diverse group nested within Rhizoclonium that may represent a case of sympatric speciation. Recent research using ribosomal DNA markers indicates that these taxa form a monophyletic group but was not able to resolve...

Lake Baikal, the oldest lake in the world, is home to spectacular biodiversity and extraordinary levels of endemism. While many of the animal species flocks from Lake Baikal are famous examples of evolutionary radiations, the lake also includes a wide diversity of endemic algae that are not well investigated with regards to molecular‐biological tax...

Molecular-assisted alpha taxonomy has provided novel ways of exploring biodiversity, and is of great help in taxa where morphology alone is not sufficient to ensure accurate species recognition or delimit species boundaries. Here, we use this approach to assess the taxonomy of Padina Adanson (Dictyotales, Phaeophyceae), a common brown algal genus i...

We present results of the study on benthic marine algae in eight localities from the coast of Campeche, Mexico. The results indicate the presence of 211 taxa of marine algae with Rhodophyta having the greatest diversity with 102 taxa, followed by Chlorophyta with 66 taxa, six varieties and four forms, Heterokontophyta with 19 species and finally Cy...
