Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Resource Availability and Use in Restored, Unmanaged, and Aquaculture Mangrove Ecosystems in Indonesia

Resources
Mangrove ecosystems are some of the most productive on our planet but have declined globally by 30–50%. Many species rely on mangrove habitats; thus, their conversion to aquaculture farms has led to noticeable losses in commodities such as wild fish ...

Towards an anthropology of acquisition: ‘How did you get that?’ Vers une anthropologie de l'acquisition : « Où as‐tu trouvé ça ? »

Journal of the Royal Anthropological Institute, EarlyView.
The production‐distribution‐consumption triad has structured how anthropologists understand exchange for roughly a century. This article argues for expanding this triad to include an explicit focus on acquisition – the systems, processes, and practices of acquiring.

Secondary periodicities of microbursts of TeV gamma rays from the Crab pulsar [PDF]

Observations were made during the past several years on the Crab pulsar using the Ooty atmospheric Cerenkov array with the aim of detecting possible emission of ultra high energy gamma rays by the pulsar.

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

Insect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

TeV radiation from the Crab nebula and other matters [PDF]

The detection of the Crab Nebula via the Cherenkov imaging technique places TeV astronomy on a secure observational footing. The motivation for TeV observations, a discussion of the atmospheric Cherenkov technique, the experimental details of the Crab ...

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

Integrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Gamma radiation from the Crab and Vela pulsars [PDF]

The young pulsars in Crab and Vela were observed as very efficient emitters of high energy gamma radiation. While their radiation in the radio, optical, and x ray range was always known to differ considerably, the gamma ray emission on a superficial ...
