Consumer resilience suppresses the recovery of overgrazed ecosystems
Abstract Many heterotroph species perish when faced with severe food limitation; others can persist, adapt, and thrive. Sea urchins are emblematic of this paradox: they can overgraze kelp forests to form barren habitats, but can then survive for decades in these nutritionally depauperate seascapes.

Abstract Human activities are increasingly driving the co‐occurrence of multiple ecological stressors, resulting in interactive and cumulative impacts that can reshape ecosystem dynamics and accelerate population declines of climate‐sensitive species. Here, we use over two decades of rocky intertidal monitoring data from 17 sites spanning over 1200 km ...

A synergistic dual‐modulation strategy integrates Ni activation via stepwise electronic regulation and La‐induced stabilization during electrochemical reconstruction. The hierarchical LaFe–CoCH/NF precursor transforms into a robust La/NiCoFeOOH interface, delivering optimized electronic structure, high turnover frequency (TOF400 = 1.23 s⁻¹), and ...

Lithic Miniaturization Provides a Signature of an MIS4‐3 Southern Dispersal of Homo sapiens
ABSTRACT Fossil and artefactual evidence shows Homo sapiens in Eurasia well before 75 ka. However, genetic evidence suggests all extant non‐African populations derive almost all of their ancestry from a dispersal that only diverged in the last 60–50 ka. In northern Eurasia, the Upper Paleolithic with its laminar blade knapping provides an archeological

Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance
Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...
