Phylogenomics recovers multiple origins of portable case-making in caddisflies (Insecta: Trichoptera), the world's most common underwater architects

This study uses phylogenomic data to reconstruct the evolutionary history of caddisflies, finding that portable case-making evolved independently in three lineages.

Trophic flexibility and hydrology structure alpine stream food webs: Implications for a fading cryosphere

The paper examines food web structure in alpine streams with different hydrologic sources, finding that subterranean ice-fed streams support unique diets and may provide critical habitat for cold-water species under climate change.

Warming undermines emergence success in a threatened alpine stonefly: a multi-trait perspective on vulnerability to climate change

The study shows that despite short-term thermal tolerance, the stonefly Lednia tumana cannot complete its life cycle at temperatures below its nymphs' CTmax, revealing vulnerabilities not captured by CTmax alone.

Summer dynamics of microbial diversity on a mountain glacier

The paper studies microbial diversity changes on a glacier over a summer melt season, finding temporal shifts in eukaryotes and algae but stability in bacteria.

Community science for enigmatic ecosystems: Using eBird to assess avian biodiversity on glaciers and snowfields

This study uses eBird community science data to assess avian biodiversity on glaciers and snowfields, finding 46 species with four specialists, and highlights the value of community science for studying remote ecosystems.

A novel camera trap design for studying wildlife in mountain glacier ecosystems yields new insight for glacier biodiversity in the Pacific Northwest, USA

This study tests a novel camera trap design for glacier ecosystems and documents wildlife and human activity in a mountain glacier in the Pacific Northwest.

Lessons from 20 years of plant genome sequencing: an unprecedented resource in need of more diverse representation

The paper reviews 20 years of plant genome sequencing, highlighting improvements in quality, taxonomic gaps, and geographic disparities in research contributions.

The biogeographic history of eelpouts and related fishes: linking phylogeny, environmental change, and patterns of dispersal in a globally distributed fish group

This study reconstructs the biogeographic history of eelpouts and related fishes using phylogenetic analysis and biogeographic modeling to link evolutionary patterns with ocean cooling events.

Geography is more important than life history in the recent diversification of the tiger salamander complex

The paper uses genetic data to show geographic isolation, not life history strategies, drives divergence in the tiger salamander complex.

Cold tolerance of mountain stoneflies (Plecoptera: Nemouridae) from the high Rocky Mountains

This study examines cold tolerance in high-elevation stoneflies from the Rocky Mountains, finding species-specific variations in supercooling points and ice enclosure survival.

Rolling stones gather moss: Movement and longevity of moss balls on an Alaskan glacier

The paper tracks movement and longevity of glacier moss balls on Root Glacier, finding they move 2.5 cm/day and persist over 6 years, with formation linked to a specific albedo stripe downwind of a nunatuk.

Headwaters fed by subterranean ice: potential climate refugia for mountain stream communities?

The paper investigates macroinvertebrate communities in alpine streams fed by different hydrological sources, finding that subterranean ice-fed streams may serve as climate refugia.

Mountain stoneflies may tolerate warming streams: evidence from organismal physiology and gene expression

This study assesses thermal tolerance in mountain stoneflies using physiological and gene expression data, finding their critical thermal maxima exceed natural stream temperatures.

To composite or replicate: how sampling method and protocol differences alter stream bioassessment metrics

This study compares how different sampling methods and sample handling protocols affect aquatic invertebrate bioassessment metrics in the Niobrara River.

Long-distance dispersal, ice sheet dynamics, and mountaintop isolation underlie the genetic structure of glacier ice worms

This study uses genome-scale data to show that ice worm populations are genetically distinct due to ice sheet dynamics and long-distance dispersal mediated by birds.
