rangr: An R package for mechanistic, spatially explicit simulation of species range dynamics

Methods in Ecology and Evolution
Global change driven by human activities is causing profound shifts in species distributions. Understanding the mechanisms that influence these dynamics is crucial for biodiversity management.

Flexible males, proactive females: increased boldness/exploration damping with time in male but not female colonists

Royal Society Open Science
Individuals colonizing new areas during range expansion encounter challenging and unfamiliar environments, suggesting that colonists should differ in behavioural traits from residents of source populations.

Significance of colour polymorphism in mountain populations of abundant leaf beetles (Coleoptera, Chrysomelidae)

Pirineos: Revista de Ecología de Montaña, 2001
[fr] Les Scarabées des feuilles deviennent spécialement communs, présentent de nombreuses espèces et sans doute peuvent jouer un rôle important sur le cycle de biomasse et le flux d'énergie des écosystèmes alpiens.

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Cultural turnover among Galápagos sperm whales [PDF]

Royal Society Open Science, 2016
While populations may wax and wane, it is rare for an entire population to be replaced by a completely different set of individuals. We document the large-scale relocation of cultural groups of sperm whale off the Galápagos Islands, in which two ...

High genetic diversity in the remnant island population of hihi and the genetic consequences of re-introduction [PDF]

, 2010
The maintenance of genetic diversity is thought to be fundamental for the conservation of threatened species. It is therefore important to understand how genetic diversity is affected by the re-introduction of threatened species.

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice

Advanced Science, EarlyView.
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.

Body Temperature Differences Between Green And Brown Grasshoppers Do Not Result From Thermal Physiology or Thermal Preferences

Ecology and Evolution
Colour polymorphisms correspond to the co‐occurrence of several distinct colour morphs that vary in hue and/or brightness, independently of sex, age or any other state‐dependent modifiers.

Dissecting the Ecological Structure of Health and Disease in the Global Gut Microbiome

Advanced Science, EarlyView.
We introduce Wiredancer, a framework that identifies three continuous ecological factors of the gut microbiota. These factors exhibit distinct patterns across health and disease, jointly capturing disrupted ecological stability and offering a new perspective for precision diagnostics and therapeutic strategies.

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.
