Hearing in the Juvenile Green Sea Turtle (Chelonia mydas): A Comparison of Underwater and Aerial Hearing Using Auditory Evoked Potentials

open access: yes, 2016
Sea turtles spend much of their life in aquatic environments, but critical portions of their life cycle, such as nesting and hatching, occur in terrestrial environments, suggesting that it may be important for them to detect sounds in both air and water.

Assessing spatial variability and efficacy of surrogate species at an ecosystem scale

open access: yesConservation Biology, EarlyView.
Abstract Preserving biodiversity is a central goal of conservation, but, in practice, monitoring biodiversity often involves assessing population trends for one or a handful of species that are presumed proxies for biodiversity. Despite the popularity of surrogate species strategies, the links between biodiversity and surrogate species are rarely ...

Ezh2 Regulates Early Astrocyte Morphogenesis and Influences the Coverage of Astrocytic Endfeet on the Vasculature

open access: yesCell Proliferation, EarlyView.
Ezh2‐deficient astrocytes showed morphologically more slender but sparse dendrites, resulting in reduced endfoot coverage and also causing disruption of the blood–brain barrier. ABSTRACT Astrocytes are crucial for central nervous system (CNS) development and function, with their differentiation being stringently controlled by epigenetic mechanisms ...

Ultrasonic songs and stridulum anatomy of Asiophlugis crystal predatory katydids (Tettigonioidea: Meconematinae: Phlugidini) [PDF]

open access: yes, 2020
The behavioural ecology of ultrasonic-singing katydids is not well understood, and the general bioacoustics, barely known for a few Neotropical Meconematinae, tends to be overlooked for species from Southeast Asia.

Automated bioacoustics: methods in ecology and conservation and their potential for animal welfare monitoring

open access: yesJournal of the Royal Society Interface, 2019
Vocalizations carry emotional, physiological and individual information. This suggests that they may serve as potentially useful indicators for inferring animal welfare.

The Free‐Range Rock Cavy (Kerodon rupestris) Communicates the Urgency of a Threat Using Different Alarm Calls

open access: yesEthology, EarlyView.
Rock cavy alarm calls are finely modulated by threat proximity. ABSTRACT This study examines whether rock cavies (Kerodon rupestris), which are social rodents, modulate their alarm calls in response to various threat contexts. Conducted across four sample areas within two study sites in the Brazilian Caatinga region, alarm calls were collected using ...

Artificial light alters spatial and temporal habitat use by a crepuscular aerial insectivore

open access: yesIbis, EarlyView.
Artificial light is increasing worldwide, and has biological effects from molecular to ecosystem levels, which may be particularly severe for crepuscular and nocturnal animals. We investigated how artificial light affected spatial and temporal patterns of habitat use by Common Nighthawks Chordeiles minor in the southern Grassland and northern Boreal ...

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Temporally-aware algorithms for the classification of anuran sounds [PDF]

open access: yes, 2018
Several authors have shown that the sounds of anurans can be used as an indicator of climate change. Hence, the recording, storage and further processing of a huge number of anuran sounds, distributed over time and space, are required in order to ...
