Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]

, 2014
Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems.

Catalyst Layer Modifications for Enhanced Performance of Fluorine‐Free Proton Exchange Membrane Fuel Cells

Advanced Energy and Sustainability Research, EarlyView.
Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.

Safe from sunburn: The divergent diel pattern of a Hydrophis sea snake

Ecology and Evolution, 2022
Diel activity patterns are an important aspect of wildlife ecology and evolution and provide valuable information for conservation and monitoring, yet for many species, activity patterns remain unstudied and may be presumed to mirror related taxa.

Diel foraging and shelter use of large juvenile brown trout (Salmo trutta) under food satiation

Knowledge and Management of Aquatic Ecosystems, 2012
The diel partitioning of juvenile brown trout Salmo trutta foraging behaviour is controlled by a number of factors including predation risk, competition, temperature and food availability.

Fine-scale differences in diel activity among nocturnal freshwater planarias (Platyhelminthes: Tricladida)

Journal of Circadian Rhythms, 2011
Background Although most freshwater planarias are well known photonegative organisms, their diel rhythms have never been quantified. Differences in daily activity rhythms may be particularly important for temperate-climate, freshwater planarias, which ...

Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin [PDF]

, 2014
Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Diel distribution and feeding habits of Neomysis mirabilis under seasonal sea ice in a subarctic lagoon of northern Japan

Aquatic Biology, 2015
We investigated the diel distribution and feeding habits of the mysid Neomysis mirabilis under seasonal sea ice in a subarctic lagoon of northern Japan. Although large individuals (>11 mm total length) were present in the eelgrass beds regardless of the ...
