The Azorean forest operations and wood industry generate considerable foliage biomass residues that are used for local essential oil (EO) production. However, research on seasonal variation of EO remains scarce. In this study, the EOs from fresh Azorean foliage (Az-CJF) collected in autumn (Aut) and spring (Spr) were obtained via hydrodistillation and investigated for their physical properties, yield, chemical composition, and bioactivities.

Alzheimer's disease (AD), a multifactorial neurodegenerative disorder characterized by severe cognitive impairment, affects millions of people worldwide. However, AD therapy remains limited and mainly symptomatic-focused, with acetylcholinesterase (AChE) inhibitors being the major available drugs. Thus, AD is considered by the WHO as a disorder of public health priority.

Department for Biological Sciences and Pathobiology, Animal Breeding and Genetics, University of Veterinary Medicine Vienna, Vienna 1210, Austria.

Article Synopsis
  • Horses have been shaped by human needs through selective breeding, leading to a very uniform male-specific portion of the Y chromosome (MSY) across modern breeds.
  • The study analyzed 1,517 males from 189 horse breeds, revealing the significant influence of Oriental stallions, especially Arabian and English Thoroughbred, over the past few centuries.
  • Additionally, the research uncovered two major historical waves of horse dissemination, including the "Spanish influence" from the Iberian Peninsula and the spread during the Ottoman Empire's expansion, highlighting the complex ancestry of modern horses.

The knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arrivals to the Archipelago and from addressing specific taxonomic lacunae.

LAQV, REQUIMTE, Laboratory of Applied Chemistry, Department of Chemical Sciences, Faculty of Pharmacy, University of Porto, Rua de Jorge Viterbo Ferreira n° 228, 4050-313, Porto, Portugal.

Styrylchromones (SC) are a group of oxygen-containing heterocyclic compounds, which are characterized by the attachment of a styryl group to the chromone core. SC can be found in nature or can be chemically synthesized in the laboratory. As their presence in nature is scarce, the synthetic origin is the most common.

Increasing water stress is emerging as a global phenomenon, and is anticipated to have a marked impact on forest function. The role of tree functional strategies is pivotal in regulating forest fitness and their ability to cope with water stress. However, how the functional strategies found at the tree or species level scale up to characterise forest communities and their variation across regions is not yet well-established.

CE3C-Centre for Ecology, Evolution and Environmental Changes, Azorean Biodiversity Group, CHANGE-Global Change and Sustainability Institute, School of Agricultural and Environmental Sciences, University of the Azores, Rua Capitão João d'Ávila, Pico da Urze, 9700-042 Angra do Heroísmo, Portugal.

This study investigates the impact of elevated temperatures on arthropod communities in intensively managed pastures on the volcanic island of Terceira, Azores (Portugal), using a functional trait approach. Open Top Chambers (OTCs) were employed to simulate increased temperatures, and the functional traits of ground dwelling arthropods were analyzed along a small elevation gradient (180-400 m) during winter and summer. Key findings include lower abundances of herbivores, coprophagous organisms, detritivores, and fungivores at high elevations in summer, with predators showing a peak at middle elevations.

  • Subterranean ecosystems, which include underground areas and water systems, are at risk from human activities, and there aren't enough protected areas to keep them safe.
  • It's tough to protect these ecosystems because it's hard to figure out exactly where they are and what lives in them, and there aren't enough scientists to study them.
  • To help protect these underground habitats, it's important for different groups to work together and come up with plans, and this guide talks about improving protected areas in Europe for better coverage of subterranean ecosystems.

Social deep-diving odontocetes face the challenge of balancing near-surface proximity to oxygen and group members with foraging in the deep sea. Individuals rely on conspecifics for critical life functions, such as predator defence, but disperse during foraging to feed individually. To understand the role of social acoustic mediation during foraging in deep-diving toothed whales, we investigated the context of social burst-pulse call production in Risso's dolphin () using biologgers.

wood industry generates large amounts of foliage biomass residues. Due to the increasing applications and markets for essential oils (EOs), fresh Azorean foliage (Az-CJF) residues are used for local EO production. Hydrodistillation (HD), a common process for obtaining EOs, also provides the possibility to fractionate them.

In defence of the entity of Macaronesia as a biogeographical region.

Biol Rev Camb Philos Soc

December 2024

School of Geography and the Environment, University of Oxford, South Parks Road, Oxford, OX1 3QY, UK.

Since its coinage ca. 1850 AD by Philip Barker Webb, the biogeographical region of Macaronesia, consisting of the North Atlantic volcanic archipelagos of the Azores, Madeira with the tiny Selvagens, the Canaries and Cabo Verde, and for some authors different continental coastal strips, has been under dispute. Herein, after a brief introduction on the terminology and purpose of regionalism, we recover the origins of the Macaronesia name, concept and geographical adscription, as well as its biogeographical implications and how different authors have positioned themselves, using distinct terrestrial or marine floristic and/or faunistic taxa distributions and relationships for accepting or rejecting the existence of this biogeographical region.
