- Evolution of neuropeptide signalling systems
Summary: A review of the revolutionary advances in our knowledge of the evolution of neuropeptide signalling systems that have been enabled by comparative genomics and neuropeptide receptor deorphanisation.
- The long and the short of it – a perspective on peptidergic regulation of circuits and behaviour
Summary: Neuropeptides are the largest class of neuromodulators in nervous systems. Here we review the general principles and mechanistic insights that have emerged from studies of various animal models and discuss some of the outstanding major challenges.
- New techniques, applications and perspectives in neuropeptide research
Summary: This Review discusses a range of molecular aspects of neuropeptide biology and integrates techniques, model organisms and applications, highlighting new perspectives enabled by technical advancements in neuropeptide research.
RESEARCH ARTICLES
- Reducing gravity takes the bounce out of running
Highlighted Article: During running, humans take higher leaps in normal gravity than in reduced gravity, in order to optimally balance the competing costs of stance and leg-swing work.
- Honey bee (Apis mellifera) sociability and nestmate affiliation are dependent on the social environment experienced post-eclosion
Summary: Sociability and nestmate affiliation in honey bees are influenced by social experience and exposure to the hive environment in early adult life.
- Directionality of nose-emitted echolocation calls from bats without a nose leaf (Plecotus auritus)
Summary: Nose-emitting bats without an obvious means of emitting a narrow bio-sonar beam still emit a highly directional beam, potentially by emitting sound through the mouth as well as the nostrils.
- Exposure to CO2 influences metabolism, calcification and gene expression of the thecosome pteropod Limacina retroversa
Summary: Severity and duration of CO2 exposure influence calcification and respiration differentially in Limacina retroversa, as shown by organismal and gene expression responses, while captivity interactively influences respiration and gene expression.
- Eating when ill is risky: immune defense impairs food detoxification in the caterpillar Manduca sexta
Editors' Choice: Appetite loss during illness occurs in all animals. It may be an important protection against food toxins. Mobilizing immune defense depresses the ability to detoxify food (as shown in caterpillars).
- Visual associative learning in wood ants
Summary: Ants form an associative memory of a visual cue paired with a reward through classical conditioning. This allows visual associative learning to be studied in fixed rather than free-moving ants.
- GABAA receptors activate fish feeding behaviour via two distinct functional pathways
Summary: Behavioural tests combined with cellular and molecular electrophysiology clarify molecular mechanisms that control fish feeding, revealing two partially competitive mechanisms originating from the same neural receptor.
- Conversion efficiency of α-linolenic acid to omega-3 highly unsaturated fatty acids in aerial insectivore chicks
Highlighted Article: A stable-isotope-labeled tracer reveals the mechanism for omega-3 highly unsaturated fatty acid (HUFA) limitation in a wild avian insectivore, showing that HUFAs are an ecologically essential nutrient.
- Ontogeny and morphometrics of the gills and swim bladder of air-breathing striped catfish Pangasianodon hypophthalmus
Summary: The paradox of how an active tropical fish can meet its oxygen requirements using gills with an apparently small surface area is explained.

Take part in the changing face of peer review
Hans Hoppeler, Editor-in-Chief, and Michaela Handel, Managing Editor, discuss the changing face of peer review in their editorial. From inclusivity in peer review and cross-referee commenting to how we’re reducing our carbon footprint, researchers are also invited to give their opinions on transparent peer review.
Seven things that shaped preLights in 2019
As 2020 gets well and truly underway, join us as we look back at seven things that shaped preLights in 2019. From launching preLists to getting nominated for an award, it was an exciting year!
Koalas climb like apes but bound like marsupials
New research by Joshua Gaschk, Celine Frère and Christofer Clemente shows that koalas bound like other marsupials when they are on the ground but they move like apes when they're climbing through branches.
An interview with Sandy Kawano
Sandy Kawano talks in her Conversation about Rick Blob helping her to find her inner palaeontologist and the tough decision she had to make when her dream job came up at George Washington University.
The stalk-eyed fly as a model for aggression – is there a conserved role for 5-HT between vertebrates and invertebrates?
In their new Commentary, Swallow et al. propose that the role of 5-HT in modulating invertebrate aggression is more nuanced that previously appreciated.
