Natural History and Environmental Patterns in the El Yali Coastal Wetland, Central Chile

Alsodes pehuenche, an endemic anuran that inhabits the Andes of Argentina and Chile, is considered “Critically Endangered” due to its restricted geographical distribution and multiple potential threats that affect it. This study is about the natural history of A. pehuenche and the physicochemical characteristics of a breeding site located in the Maule mountain range of central Chile. Moreover, the finding of its clutches in Chilean territory is reported here for the first time. Finally, a description of the number and morphology of these eggs is provided.

Moral Stance

Abstract The natural history of our moral stance told here in this commentary reveals the close nexus of morality and basic social-cognitive capacities. Big mysteries about morality thus transform into smaller and more manageable ones. Here, I raise questions regarding the conceptual, ontogenetic, and evolutionary relations of the moral stance to the intentional and group stances and to shared intentionality.

Biochemical Difference

In the eye lens emerging molecular and structural patterns apparently cohabit with the remnants of the past. The lens in a rather puzzling fashion sums up its own natural history and even transient steps of the differentiation are memorized. A prototype of this situation is well outlined by the study of the lenticular intercellular junctions. These membrane domains exhibit structural, biochemical and perhaps functional polymorphism reflecting throughout life the multiple steps of the differentiation of the epithelium into fibers and of the ageing process of the lenticular cells.The most striking biochemical difference between the membrane derived from the epithelium and from the fibers respectively, concerns the presence of the 26,000 molecular weight polypeptide (MP26) in the latter membranes.
