Physiological and Agronomic Responses of Four Rice Varieties to Drought in the Rainforest

open access: yesNotulae Scientia Biologicae, 2018
The present investigation tested the hypothesis that there would be variation in physiological responses to water deficit among rice varieties from different production ecologies, with contrasting tolerance to water deficit under repeated cycle of soil ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

A micro-perspective on variation and universals [PDF]

open access: yes, 2017
This paper approaches the questions raised in the workshop description surrounding universals and variation from the perspective of microvariation. Throughout this document we frequently refer to van Craenenbroeck and van Koppen (2016) (henceforth VCVK),

Smooth-car mixed models for spatial count data [PDF]

open access: yes, 2008
Penalized splines (P-splines) and individual random effects are used for the analysis of spatial count data. P-splines are represented as mixed models to give a unified approach to the model estimation procedure.

Body-Size Change in a Rodent Is Affected by Environmental Warming and Population-Specific Thermoneutral Zone

open access: yesAnimals
Rodent body size often exhibits a diversity of temperature–size patterns among and within species, which might be caused by differential thermoneutral zones (TNZs) and experienced extents of warming.
