Taxonomy and species richness estimates for the genus Caulerpa have proven challenging due to the difficulty of assessing morphological species limits. In the present study we evaluate the taxonomy of the genus and assess ...

The authors presents 77 species new to science, distributed from Mexico, through Central and South America, as far as Argentina. They are distributed in Colombia (33), Peru (27), Ecuador (15), Costa Rica (5), Brazil (3), ...

Mating behavior in Centruroides margaritatus, as in other scorpion species, includes a series of rapid rocking or shaking movements of the male (“juddering”). It has been suggested that substrate vibrations are generated ...

The mammalian Y Chromosome sequence, critical for studying male fertility and dispersal, is enriched in repeats and palindromes, and thus, is the most difficult component of the genome to assemble. Previously, expensive ...

Long-term monitoring and phenological patterns of microbial communities are rare in the scientific literature. Myxomycetes have life cycle characteristics that allow both to be documented. The present study summarizes ...

Adult females of Helvibis longicauda accumulated tiny pieces of vegetation in the mesh of their webs. The amount of debris accumulated was much greater in webs of spiders with either egg sacs, spiderlings or juveniles than ...

Se aportan los datos necesarios para validar la publicación del nombre orquidáceo Kefersteinia retanae por G. Gerlach en 1994.

Herbivores can gain indirect access to recalcitrant carbon present in plant cell walls through symbiotic associations with lignocellulolytic microbes. A paradigmatic example is the leaf-cutter ant (Tribe: Attini), which ...

We studied the adsorption ability and tolerance of the thermophilic filamentous cyanobacteria Letolyngbya 7M towards Paraquat and Bromacil. Adsorption isotherms at pH = 7.0 showed an adsorption capacity of 24.4 mg/g and ...

A new species of Specklinia from the Cordillera de Talamanca in southern Costa Rica and western Panama is described and illustrated. Specklinia absurda most closely resembles Specklinia fuegi. It differs from that species ...
