Effects of different types of leisure activities on working memory across the adult lifespan.

The aim of the present study was to contrast the potential influence of five independent types of leisure activities (physical, mental, social, cultural, and passive) on working memory in a lifespan sample and in specific stages of adulthood (young, middle-aged, and older adults). A sample of 1652 healthy adults between 21 and 80 years of age participated in the study. Leisure activities were assessed through a lifestyle questionnaire created for the study.

Is the invasive Caprella scaura Templeton, 1836 displacing its resident congener Caprella equilibra Say, 1818 in marinas of the South Iberian Peninsula? A long-term spatio-temporal approach.

Although marine invasions are increasingly a matter of concern, the impact of invasive species in the ecosystem and their ability to replace native taxa is still little understood. Data from 2011 to 2021 in marinas of the Southern Iberian Peninsula supported that the invasive amphipod Caprella scaura is replacing the resident Caprella equilibra over time. Six marinas where C.

Facilitation of macrofaunal assemblages in marinas by the habitat-forming invader Amathia verticillata (Bryozoa: Gymnolaemata) across a spatiotemporal scale.

Widespread habitat-forming invaders inhabiting marinas, such as the spaghetti bryozoan Amathia verticillata, allow exploring facilitation processes across spatiotemporal contexts. Here we investigate the role of this bryozoan as habitat for native and exotic macrofaunal assemblages across different ecoregions of Western Mediterranean and East Atlantic coasts, and a monthly variation over a year. While only 7 (all peracarid crustaceans) of the 54 associated species were NIS, they dominated macrofaunal assemblages in terms of abundance, raising the potential for invasional meltdown.

Estuarine versus coastal marinas: Influence of the habitat on the settlement of non-indigenous peracarids on the polychaete Sabella spallanzanii (Gmelin, 1791).

Recreational marinas are key points for the introduction and secondary spread of non-indigenous species (NIS). However, little is known about the influence of the habitat surrounding the marina on NIS communities. To explore this issue, we compared peracarid assemblages associated to the widespread ecosystem engineer Sabella spallanzanii in lower estuarine marinas (with oceanic salinity) and coastal marinas of the south of the Iberian Peninsula.

Metamemory Mediates the Effects of Age on Episodic and Working Memory across the Adult Lifespan.

Background: Previous studies have examined the direct relationship between metamemory and memory performance in young and older adults, but the results of these studies have been inconsistent. Therefore, we examined whether metamemory mediates the effects of age on memory performance.

Methods: We examined episodic memory and working memory through computerized tasks performed by a lifespan sample of 1554 healthy adults.
