Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges
Angewandte Chemie International Edition, EarlyView.Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

The determination of par levels from absorption coefficient profiles at 490 nm
Ciencias Marinas, 1999 A model is presented that allows the prediction of percent photosynthetically available radiation (PAR) levels from measured profiles of the absorption coefficient at 490 nm in the Gulf of California. Percent PAR levels depend on the diffuse attenuation

Atmospheric input and concentration of dissolved iron in the surface layer of the Gulf of California
Ciencias Marinas, 2009 A survey was conducted to determine the atmospheric input of particulate iron (Fep) and the factors and processes controlling the concentration and distribution of dissolved iron (Fed) in surface water (200 m) of the central Gulf of California ...

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece
The Anatomical Record, EarlyView.The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Hydraulic Jump in the Gulf of California
Open Journal of Marine Science, 2012 Acoustic Doppler current profiles and water density profiles were measured over the 280 m deep continental slope of the Gulf of California to elucidate the bathymetric effect on zooplankton distribution. These measurements were combined with water velocity and density simulations from the Regional Ocean Model System with and without the influence of ...

The Anatomical Record, EarlyView.Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
