DEBBIES Dataset to study Life Histories across Ectotherms

open access: yesScientific Data
Demographic models are used to explore how life history traits structure life history strategies across species. This study presents the DEBBIES dataset that contains estimates of eight life history traits (length at birth, puberty and maximum length ...

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

open access: yesJournal 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 ...

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Cleaner wrasse failed in early testing stages of both visual and spatial working memory paradigms

open access: yesAnimal Cognition
Working memory (WM), an attention-based short-term storage system responsible for the manipulation and integration of past knowledge with present information for goal-directed behavior, is a key executive function and a principal predictor of general ...

Too hot for comfort: Elevated temperatures influence gene expression and exceed thermal tolerance of bigmouth shiners, Ericymba dorsalis

open access: yesJournal of Fish Biology, EarlyView.
Abstract Environmental and associated ecosystem change may affect the persistence of fish species based on their ability to adapt to changing conditions, including decreasing flows and rising water temperatures. Exceeding the thermal tolerances of stream fish will likely result in a loss of ability to maintain metabolic processes.

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

open access: yesJournal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Rapid postfire color shift in a Mediterranean lizard

open access: yesJournal of Zoology, EarlyView.
We quantified dorsal luminosity and color composition of Psammodromus algirus in burned and adjacent unburned habitats at different times since fire. Lizards inhabiting recently burned areas displayed lighter dorsal coloration, particularly during the early stages of postfire succession, with the effect being more pronounced in larger individuals ...

Variation in herbivore defense strategies among plant species differing in elevational distribution and the role of temperature in defense

open access: yesNew Phytologist, EarlyView.
Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.
