Novel evidence of interaction between killer whales (Orcinus orca) and juvenile white sharks (Carcharodon carcharias) in the Gulf of California, Mexico

Frontiers in Marine Science
White sharks (Carcharodon carcharias), have only one known natural predator in the ocean, the orca or killer whale (Orcinus orca). While interactions between these coexisting apex predators are known to occur, killer whales are adept at subduing adult ...

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

Journal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Enhancing satellite-based detection of marine fauna using synthetic data

Ecological Informatics
Satellite imagery could offer a powerful, non-invasive tool for large-scale whale population monitoring. However, its effectiveness is constrained by limited annotated training data, the high cost of very high-resolution imagery, and restrictions on data

Running scared: when predators become prey

Ecosphere, 2019
Apex predators play an important role in structuring food webs and are thus key components of healthy, stable ecosystems. While the loss of apex predators has been shown to disrupt ecosystems and trigger trophic cascades, the introduction of novel apex ...

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Contextual Learning of New Meanings for Familiar Words: Perturbation of Original Meanings Occurs Without Deliberate Study

Language Learning, EarlyView.
Abstract The present study investigated learning new meanings of known words from reading, following Hulme et al.’s (2018) study. English speakers read four short stories containing 16 critical words (i.e., familiar word forms assigned invented secondary meanings).

The Painterly Materiality of Clouds in Antony and Cleopatra and Hamlet

Renaissance Studies, EarlyView.
Abstract This article examines the cloud‐gazing scenes in Antony and Cleopatra and Hamlet through the lens of early modern artistic theory and material practices, particularly the art of limning. Building upon existing philosophical and poetic interpretations of Shakespearean clouds as metaphors for ephemerality and memory, the essay argues that the ...

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style

Renaissance Studies, EarlyView.
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral
