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

Insulin or insulin-like studies on unicellular organisms: a review

open access: yesBrazilian Archives of Biology and Technology, 2004
This paper presents a review of studies about insulin and insulin-like substances in prokaryotes, eukaryotes and fungi have been published over the last two decades, constituting an updating of our previous review (1988) which included references to ...

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.

Invertebrate biomechanics [PDF]

open access: yesCurrent Biology, 2017
Invertebrate biomechanics focuses on mechanical analyses of non-vertebrate animals, which at root is no different in aim and technique from vertebrate biomechanics, or for that matter the biomechanics of plants and fungi. But invertebrates are special - they are fabulously diverse in form, habitat, and ecology and manage this without the use of hard ...

Seasonal invertebrate communities in multiple use jarrah forests. Implications for conservation and management [PDF]

open access: yes, 2004
The response of ground-dwelling jarrah forest invertebrates to logging (but not a post-harvest burning) was examined in the Kingston, Warrup and Winnejup forest blocks, approximately 25 km north-east of Manjimup in the south-west of Western Australia ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

open access: yesAdvanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

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.
