Phylogenetic mapping of scale nanostructure diversity in snakes

open access: yesBMC Evolutionary Biology, 2019
Background Many species of snakes exhibit epidermal surface nanostructures that form complex motifs conferring self-cleaning properties, and sometimes structural iridescence, to their skin.

Classical Evolution without Evolution

open access: yesUniverse, 2023
The well-known argument of Page and Wootters demonstrates how to “derive" the usual quantum dynamics of a subsystem in a global state which is an eigenstate of the total Hamiltonian. I show how the same argument can be made in classical physics by using a formalism that closely resembles the quantum one.

The transcriptome landscape of the carcinogenic treatment response in the blind mole rat: insights into cancer resistance mechanisms

open access: yesBMC Genomics, 2019
Background Spalax, the blind mole rat, developed an extraordinary cancer resistance during 40 million years of evolution in a subterranean, hypoxic, thus DNA damaging, habitat.

Evolution of evolution of superbubbles [PDF]

open access: yesInternational Astronomical Union Colloquium, 1997
AbstractIn the first place, I will summarize the evolution of our picture of the ISM over the past several decades in order to see the importance of superbubbles for ISM structure. In accordance with the progress of observations, the picture of the ISM has dramatically changed from the 1960s.

Evolution is Viral: The Theory of Collective Discontinuous Evolution [PDF]

open access: yes, 2010
Herein will be discussed the problems associated with the origin of species according to Darwinist processes of individual mutations. We will argue that individual mutations cannot be the driving force of species origination.

Taxonomic diversity and abundance of enchytraeids (Annelida, Clitellata, Enchytraeida) in the Northern Palaearctic. 1. Asian part [PDF]

open access: yesBiodiversity Data Journal
Enchytraeids, or potworms, are tiny oligochaetes that are distributed worldwide in many terrestrial, freshwater and marine ecosystems. Despite their key role in the functioning of ecosystems, the diversity and abundance of Enchytraeidae are rarely ...

Sampling environmental DNA from trees and soil to detect cryptic arboreal mammals

open access: yesScientific Reports, 2023
Environmental DNA (eDNA) approaches to monitoring biodiversity in terrestrial environments have largely focused on sampling water bodies, potentially limiting the geographic and taxonomic scope of eDNA investigations.

Rapid generation of ecologically relevant behavioral novelty in experimental cichlid hybrids

open access: yesEcology and Evolution, 2020
The East African cichlid radiations are characterized by repeated and rapid diversification into many distinct species with different ecological specializations and by a history of hybridization events between nonsister species.

Governing the Commons: The Evolution of Institutions for Collective Action

open access: yes, 1993
In 1985, the National Academy of Sciences sponsored a conference in Annapolis, Maryland, to discuss common property resource management. This conference was a watershed in the development of the theoretical underpinning of institutional design for ...
