Marine invertebrates as proxies for early kelp use along the western coast of South America

Frontiers in Earth Science, 2023
Coastal societies have lived at the seaward edge of the Atacama Desert since at least 12,000 years ago. Kelp forest ecosystems provide evidence for important subsistence activity along the entire Chilean coast through fishing and gathering. Despite their

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.

The Effect of Differential Flow Speeds and Kelp Morphology on Membranipora membranacea Settlement

, 2021
Kelp provides important habitats for a large variety of organisms such as epiphytic bryozoans. The relationship between the bryozoan and their kelp substrate is influenced by biological, chemical, and physical factors.

Seasonal and inter-annual dynamics of a Macrocystis pyrifera forest in Concepcion Bay, Chile

Ecological Informatics
Kelp forest are foundation species that deliver key ecosystem services for coastal habitats. Chile is one of the largest exporters of kelp biomass, which relies on the harvesting of wild populations.

The value of ecosystem services in global marine kelp forests

Nature Communications, 2023
While marine kelp forests have provided valuable ecosystem services for millennia, the global ecological and economic value of those services is largely unresolved.

Games and gamification projects in the Australian public sector

Australian Journal of Public Administration, EarlyView.
Abstract This article surveys the arrival of gameful government into Australian public sector practice. Gameful government is a shorthand, descriptive term denoting the interpenetration of (video)games, and design elements and thinking from them, into public sector work.

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Variation in Population Structure and Standing Stocks of Kelp Along Multiple Environmental Gradients and Implications for Ecosystem Services

Frontiers in Marine Science, 2021
There is an increasing focus on ecosystem services provided by macroalgae worldwide, many which depend on its structural and morphological characteristics.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Assessing the role of natural kelp forests in modifying seawater chemistry

Scientific Reports
Climate change is causing widespread impacts on seawater pH through ocean acidification (OA). Kelp forests, in some locations can buffer the effects of OA through photosynthesis.
