Diferenciación morfométrica de los géneros Poblana, Chirostoma y Menidia (Osteichthyes: Atherinopsidae) [PDF]

, 2021
Background: The recent origin of the genera Chirostoma and Poblana, and the scarce morphological differentiation between them, have made it difficult to define their taxonomic validity, in addition to the fact that both genera share a common ancestor ...

Identifying microbial life in rocks: Insights from population morphometry

Geobiology, Volume 18, Issue 3, Page 282-305, May 2020., 2020
Abstract The identification of cellular life in the rock record is problematic, since microbial life forms, and particularly bacteria, lack sufficient morphologic complexity to be effectively distinguished from certain abiogenic features in rocks. Examples include organic pore‐fillings, hydrocarbon‐containing fluid inclusions, organic coatings on ...

Microbialite response to an anthropogenic salinity gradient in Great Salt Lake, Utah. [PDF]

, 2017
A railroad causeway across Great Salt Lake, Utah (GSL), has restricted water flow since its construction in 1959, resulting in a more saline North Arm (NA; 24%-31% salinity) and a less saline South Arm (SA; 11%-14% salinity).

Bacterial Diversity in the Hyperalkaline Allas Springs (Cyprus), a Natural Analogue for Cementitious Radioactive Waste Repository [PDF]

, 2016
The biogeochemical gradients that will develop across the interface between a highly alkaline cementitious geological disposal facility for intermediate level radioactive waste and the geosphere are poorly understood.

Profundal benthic invertebrates in an oligotrophic tropical lake: different strategies for coping with anoxia

Journal of Limnology, 2014
The deep benthic communities of tropical lakes are poorly understood with respect to their composition, abundance, biomass and regulatory factors. Whereas the hypolimnia of temperate oligotrophic lakes remain oxygenated, the higher temperatures in ...

Estimation of the eddy diffusivity coefficient in a warm monomictic tropical Lake

Journal of Limnology, 2016
We used a two-year dataset (1998-1999) of monthly temperature profiles from Lake Alchichica, Mexico to estimate values of the vertical coefficient of eddy diffusivity.
