Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

open access: yesJournal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

open access: yesJournal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Multidecadal Changes in the Flow Velocity and Mass Balance of the Hailuogou Glacier in Mount Gongga, Southeastern Tibetan Plateau

open access: yesRemote Sensing
Maritime glaciers in the southeastern Tibetan Plateau (TP) have experienced important changes in mass and dynamics over the past decades, challenging the regional water supply and glacier-related hazards. However, knowledge about long-term variations in the surface velocity and mass balance of maritime glaciers remains incomplete due to the lack of ...

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

open access: yesNew Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Annual and Seasonal Variations in Glacier Velocity, and Surging Glaciers in the West Kunlun Mountain

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Monitoring glacier velocity is crucial for revealing glacier dynamics and clarifying the responses of glaciers to climate change. The West Kunlun mountain (WKM) is at the center of the Karakoram Anomaly; however, insufficient systematic studies have been

Brief communication: Potential of satellite optical imagery to monitor glacier surface flow velocity variability in the tropical Andes

open access: yesThe Cryosphere
Abstract. We present an analysis of glacier dynamics in mountain ranges of the tropical Andes of southern Peru and Bolivia using satellite data from 2013 to 2022. Despite the challenges posed by small glaciers (width<500 m), low velocities (<100myr-1), and high cloudiness during the monsoon, we map annually aggregated surface velocities and ...

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Increasing Respiration Weakens the Carbon Sink Over Two Decades in a Temperate Deciduous Forest

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Using a 20‐year eddy covariance record from a temperate deciduous forest, we show that net carbon uptake declined over two decades. Both the trend and interannual variability in net carbon exchange were respiration driven, with warming winters and increasing late‐summer diffuse light driving the trend in respiration.

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 760-776, September 2026.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.
