Why are so few island bryophytes endemic?

ABSTRACT: Endemism, a hallmark of island biodiversity, reaches its lowest levels among bryophytes compared with other land plants. Whether this pattern reflects low diversification rates, and why, or whether it is a result of loss of endemicity due to extinctions or subsequent continental (back-)colonization, is examined here through a review of available evidence in the Macaronesian flora. Significant genetic ...

Subterranean environments contribute to three-quarters of classified ecosystem ...

ABSTRACT: Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well-being. Subterranean ecosystems are integral to major biogeochemical cycles, sustain diverse surface habi...

New occurrence data of bryophytes and lichens from São Jorge Island (Azores, Ma...

ABSTRACT: The Azorean Archipelago hosts an exceptionally rich cryptogamic flora, although several islands remain comparatively understudied. To address this gap, the present study presents records of bryophytes and lichens from São Jorge Island (SJO), based on opportunistic collections made during a MOVECLIM – Azores project expedition, from 29 July to 2 August 2014. Sampling was based on direct observation of ...

MOVECLIM–AZORES: plot based vascular plant cover along elevational gradients (2...

ABSTRACT: In the scope of the MOVECLIM project, in 2013, we surveyed vascular plants and their ground cover in native or better-preserved vegetation patches, following an elevational transect, on four Azorean islands (São Miguel, Terceira, Pico and Flores). Using a standardised, plot-based protocol, permanent 10 m × 10 m plots were established at approximately 200 m elevation steps, each plot subdivided into fo...

Monitoring of potential invasive arthropod species in Azores Islands (Corvo, Fl...

ABSTRACT: Arthropods provide essential ecosystem services, yet multiple lines of evidence indicate widespread declines driven by habitat loss (degradation, fragmentation and reduction), biological invasions and climate change. Oceanic islands are particularly vulnerable to invasive alien species because of their isolation, small area and sensitivity to novel predators, competitors and pathogens. In the Azores, ...

Integrating plot-based methods for monitoring biodiversity in island habitats u...

Oceanic island native forests have become highly fragmented and yet host a disproportionate share of endemic arthropod diversity. Long-term monitoring and conservation planning are often limited by the scarcity of standardised, plot-based datasets for key indicator taxonomic groups, such as the megadiverse beetles (Coleoptera). Under the scope of the projects EU-NETBIOME grant 0003/2011, FCT MACDIV – FCT-PTDC/B...

Desvendar a complexidade das florestas: como o LiDAR e os drones estão a transf...

As florestas estão entre os ecossistemas mais complexos e vitais da Terra. Ao manter a biodiversidade, as florestas asseguram a resiliência e a estabilidade dos ecossistemas, oferecendo serviços essenciais. Desempenham também um papel fundamental na regulação do clima global através do seu papel no ciclo do carbono.

Diversity and Distribution of Bryophytes Along an Altitudinal Gradient on Flore...

ABSTRACT: Altitudinal gradients offer powerful natural frameworks to investigate how environmental factors shape biodiversity, especially on young oceanic volcanic islands where short spatial distances encompass sharp climatic transitions. This study documents bryophyte diversity and examines how elevation, substrate, and environmental variables influence the structure of bryophyte communities on Flores Island ...

Discovering the allure of forests: Exploring adolescent queries in nature-rich ...

ABSTRACT: This study explores adolescents’ inherent curiosity about nature through the production of self-generated questions during a field visit to a nature-rich environment, followed by descriptive-interpretative analysis using focus groups. Utilizing cultural probes and content-free question tokens, we collected 164 valid questions produced by 36 adolescents during the field session. Biotic elements, like s...
