Sneaking into a Hotspot of Biodiversity: Coverage and Integrity of a Rhodolith Bed in the Strait of Sicily (Central Mediterranean Sea)

2022

Habitat mapping, physical characteristics and benthic community of a rhodolith bed in the Pelagie Islands (Strait of Sicily, Mediterranean Sea) were studied through Multi–Beam Echo–Sounder (MBES), Remotely Operated Vehicle (ROV) and grab samples. The geomorphological analysis revealed an articulated and wide rhodolith bed; video inspections highlighted a bed with high coverage, few sandy patches and with a prevalence of the boxwork morphotype. A total of 207 taxa with 876 specimens were identified, and Polychaeta was the dominant taxon. Linguimaera caesaris, a Lessepsian benthic amphipod, was recorded in all sampling sites, and its presence represents an input to deepen the benthic assembla…

Effects of forest-fuel harvesting on the diversity of dead wood and epixylic macrolichens in clear-cuts

2016

Energiapuuta käytetään yhä enemmän uusiutuvan energian lähteenä. Energiapuun korjuussa hakkuutähteitä eli kantoja, oksia ja latvuksia kerätään päätehakkuun ja harvennuksen yhteydessä hakkuualoilta. Tämä vähentää erityisesti pienikokoisen lahopuun ja kantojen määrää. Lahopuu on tärkeä resurssi boreaalisissa metsissä, mutta sen määrä talousmetsissä on alhainen luonnonmetsiin verrattuna. Määrän väheneminen edelleen energiapuun korjuun seurauksena voi johtaa lahopuusta riippuvaisen monimuotoisuuden vähenemiseen, minkä vuoksi on tärkeää tutkia energiapuun korjuun monimuotoisuusvaikutuksia. Teoriat pinta-alan ja habitaatin heterogeenisyyden vaikutuksesta lajimäärään ovat yksiä tärkeimmistä lajimä…

Predicting valuable forest habitats using an indicator species for biodiversity

2020

Intensive management of boreal forests impairs forest biodiversity and species of old-growth forest. Effective measures to support biodiversity require detection of locations valuable for conservation. We applied species distribution models (SDMs) to a species of mature forest, the northern goshawk (Accipiter gentilis, goshawk), that is often associated with hotspots of forest biodiversity. We located optimal sites for the goshawk on a landscape scale, assessed their state under intensified logging operations and identified characteristics of goshawks' nesting sites in boreal forests. Optimal sites for the goshawk covered only 3.4% of the boreal landscape and were mostly located outside pro…

Do large‐scale associations in birds imply biotic interactions or environmental filtering?

2023

Aim There has been a wide interest in the effect of biotic interactions on species' occurrences and abundances at large spatial scales, coupled with a vast development of the statistical methods to study them. Still, evidence for whether the effects of within-trophic-level biotic interactions (e.g. competition and heterospecific attraction) are discernible beyond local scales remains inconsistent. Here, we present a novel hypothesis-testing framework based on joint dynamic species distribution models and functional trait similarity to dissect between environmental filtering and biotic interactions. Location France and Finland. Taxon Birds. Methods We estimated species-to-species association…

Comparison of methods to model species habitat networks for decision-making in nature conservation : the case of the wildcat in southern Belgium

2020

Facing the loss of biodiversity caused by landscape fragmentation, implementation of ecological networks to connect habitats is an important biodiversity conservation issue. It is necessary to develop easily reproducible methods to identify and prioritize actions to maintain or restore ecological corridors. To date, several competing methods are used with recurrent debate on which is best and if expert-based approaches can replace data-driven models. We compared three methods: knowledge-driven (expert based), data-driven (based on species distribution model), and a mixed approach. We quantified their differences in habitat and corridor mapping, and prioritizations of landscape elements in t…

Smartphone usage among older adults

2021

Abstract Problematic smartphone usage, associated with impaired daily functioning, has gained increased attention among researchers. However, extant research is focusing on adolescents and younger adults. This paper investigates smartphone usage among older adults, of which less is known. To do so, we conducted a cross-sectional survey of 154 smartphone users (60+ years) in Norway using structural equation modeling (PLS-SEM). We examined the contributing roles of loneliness, habit, social influence, emotional gain, fear of missing out, self-control, and problematic smartphone usage. We further investigated how older adults engage with their smartphones. Our findings suggest that older adult…

A habit is a regularity in automatic responding to a specific situation. Classical learning psychology explains the emergence of habits by an extended learning history during which the response becomes associated to the situation (learning of stimulus-response associations) as a function of practice ("law of exercise") and/or reinforcement ("law of effect"). In this paper, we propose the "law of recency" as another route to habit acquisition that draws on episodic memory models of automatic response regulation. According to this account, habitual responding results from (a) storing stimulus-response episodes in memory, and (b) retrieving these episodes when encountering the stimulus again. …

Jóvenes transitando a la educación posobligatoria: el reflejo de la injusticia hermenéutica en sus discursos

2020

Los factores que influyen en las elecciones de los jóvenes a la hora de transitar de la etapa educativa obligatoria a la posobligatoria han sido ampliamente estudiados. La confluencia de factores estructurales y de agencia en las transiciones escolares ha sido probada. Sin embargo, estos resultados no necesariamente reflejan la conciencia que los jóvenes tienen de dichos condicionantes, así como la medida en que consideran que estos les afectan. Sostiene Miranda Fricker (2017) que cuando una grieta en los recursos de interpretación colectivos hace que una o varias personas se encuentren en posición de desventaja con respecto a la comprensión de sus propias experiencias sociales, está tenien…

Current agri-environmental policies dismiss varied perceptions and discourses on management of traditional rural biotopes

2017

Abstract Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners’ decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist’s, profit-oriented farmer…
