Ecology and Evolution, Volume 11, Issue 2, Page 714-734, January 2021., 2021 Extended maternal care past age 1 was common in Steller sea lions, but ranged geographically (e.g., 0.54–0.86 were weaned at age 1); where offspring were smallest, weaning was later. Earlier weaning and larger offspring were associated with reduced adult female survival but were unrelated to population trends, suggesting this trait may be optimized for

Augmented generation of protein fragments during wakefulness as the molecular cause of sleep: A hypothesis [PDF]
, 2012 Despite extensive understanding of sleep regulation, the molecular-level cause and function of sleep are unknown. I suggest that they originate in individual neurons and stem from increased production of protein fragments during wakefulness.

The biology and evolution of music: A comparative perspective [PDF]
, 2006 Studies of the biology of music (as of language) are highly interdisciplinary and demand the integration of diverse strands of evidence. In this paper, I present a comparative perspective on the biology and evolution of music, stressing the value of ...

Development of body mass and sexual size dimorphism in Danish red foxes (Vulpes vulpes) [PDF]
, 2018 In this study, we examine the development of body mass and sexual size dimorphism (SSD) in 178 juvenile wild Danish red foxes from 99 litters using piecewise analyses of regression lines for age versus weight.

The Dynamic Proliferation of CanSINEs Mirrors the Complex Evolution of Feliforms [PDF]
, 2014 Background: Repetitive short interspersed elements (SINEs) are retrotransposons ubiquitous in mammalian genomes and are highly informative markers to identify species and phylogenetic associations. Of these, SINEs unique to the order Carnivora (CanSINEs)

New C‐Terminal Conserved Regions of Tafazzin, a Catalyst of Cardiolipin Remodeling
Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019 Cardiolipin interacts with many proteins of the mitochondrial inner membrane and, together with cytochrome C and creatine kinase, activates them. It can be considered as an integrating factor for components of the mitochondrial respiratory chain, which provides for an efficient transfer of electrons and protons.

A framework for integrating thermal biology into fragmentation research
Ecology Letters, Volume 19, Issue 4, Page 361-374, April 2016., 2016 Abstract Habitat fragmentation changes thermal conditions in remnant patches, and thermal conditions strongly influence organism morphology, distribution, and activity patterns. However, few studies explore temperature as a mechanism driving ecological responses to fragmentation. Here we offer a conceptual framework that integrates thermal biology into
