Oxygen is a better predictor of macroinvertebrate richness than temperature—a systematic review

open access: yesEnvironmental Research Letters, 2021
Despite ongoing loss of diversity in freshwater ecosystems, and despite mitigation measures to halt this loss, it is still not clear what ecological drivers underlies lotic biodiversity.

Does Handling for Public Talks in Zoos Affect the Behaviour of Captive Mexican Red-Kneed Spiders Brachypelma hamorii?

open access: yesJournal of Zoological and Botanical Gardens, 2022
Zoos include invertebrates in visitor interaction sessions to educate and spread conservation messages to the public. Yet, the welfare implications of these encounters on invertebrates are unstudied.

Combined Effects of Ziziphus jujuba, Dimocarpus longan, and Lactuca sativa on Sleep-Related Behaviors through GABAergic Signaling

open access: yesFoods, 2023
We aimed to analyze the increase in the sleep-promoting effects based on the mixed ratio of botanical extracts, Ziziphus jujuba seeds, Dimocarpus longan fruits, and Lactuca sativa leaves, using animal models. Behavioral analyses, including an analysis of

Can aggregate quarry silt lagoons provide resources for wading birds? [PDF]

open access: yes, 2017
Wading birds have declined across Europe as the intensification of lowland agriculture has resulted in the loss and degradation of wetland areas. Lowland aggregate extraction sites that incorporate areas of fine, waste sediments deposited in silt lagoons

Vertebrate and Invertebrate Animal and New In Vitro Models for Studying Neisseria Biology

open access: yesPathogens, 2023
The history of Neisseria research has involved the use of a wide variety of vertebrate and invertebrate animal models, from insects to humans. In this review, we itemise these models and describe how they have made significant contributions to ...

Benthic and interstitial habitats of a lentic spring as invertebrate refuges during supra-seasonal drought [PDF]

open access: yes, 2013
Instream refuges are places where invertebrates persist during disturbances due to reduced adverse impacts. During droughts, low flows may be accompanied by elevated temperatures, and potential refuges including subsurface sediments and spring-fed ...

Peptide Cotransmitters as Dynamic, Intrinsic Modulators of Network Activity

open access: yesFrontiers in Neural Circuits, 2018
Neurons can contain both neuropeptides and “classic” small molecule transmitters. Much progress has been made in studies designed to determine the functional significance of this arrangement in experiments conducted in invertebrates and in the vertebrate

Higher Network Activity Induced by Tactile Compared to Electrical Stimulation of Leech Mechanoreceptors

open access: yesFrontiers in Physiology, 2018
The tiny ensemble of neurons in the leech ganglion can discriminate the locations of touch stimuli on the skin as precisely as a human fingertip. The leech uses this ability to locally bend the body-wall away from the stimulus. It is assumed that a three-

The invertebrate Caenorhabditis elegans biosynthesizes ascorbate. [PDF]

open access: yes, 2015
l-Ascorbate, commonly known as vitamin C, serves as an antioxidant and cofactor essential for many biological processes. Distinct ascorbate biosynthetic pathways have been established for animals and plants, but little is known about the presence or ...
