Escherichia Species Diversity Across Pristine and Impacted Catchments: Evidence for Avian Sources of Escherichia marmotae in Aotearoa/New Zealand

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Escherichia spp. were obtained from pristine and impacted environments to define community structure and assess potential human health risks. E. coli was more prevalent from sites affected by livestock or human activities, whereas non‐E. coli Escherichia spp. were more prevalent in avian faeces and native forest with fewer faecal sources.

Pioneer's Anomaly and the Solar Quadrupole Moment

open access: yes, 2005

The implications of fire management in the Andean paramo: A preliminary assessment using satellite remote sensing [PDF]

open access: yes, 2015
The upper ranges of the northern Andes are characterized by unique Neotropical, high altitude ecosystems known as paramos. These tundra-like grasslands are widely recognized by the scientific community for their biodiversity and their important ecosystem

New derivation of the Lagrangian of a perfect fluid with a barotropic equation of state [PDF]

open access: yes, 2012
In this paper we give a simple proof that when the particle number is conserved, the Lagrangian of a barotropic perfect fluid is $\mathcal{L}_m=-\rho [c^2 +\int P(\rho)/\rho^2 d\rho]$, where $\rho$ is the \textit{rest mass} density and $P(\rho)$ is the ...

Inferring possible population divergence in Espeletia pycnophylla (Asteraceae) through morphometric and paleogeographic approaches

open access: yesRevista de Biología Tropical, 2010
The phenotypic structure within and between plant populations is generally influenced by their distribution patterns in space and time; therefore, the study of their divergence is a central issue for the understanding of their microevolutive processes ...

First record of the rain frog Pristimantis myersi (Goin & Cochran, 1963) (Anura, Craugastoridae) for Ecuador [PDF]

open access: yesCheck List, 2015
Pristimantis myersi is a small Andean frog that inhabits paramos, sub-paramos and upper Andean forests at elevations between 2,900–3,275 m. It is known from about a dozen localities in the southern end of the Cordillera Central of the Colombian Andes ...

Nonminimal torsion-matter coupling extension of f(T) gravity

open access: yes, 2014
We construct an extension of f(T) gravity with the inclusion of a non-minimal torsion-matter coupling in the action. The resulting theory is a novel gravitational modification, since it is different from both f(T) gravity, as well as from the non-minimal
