DNA-based monitoring of biodiversity has revolutionised our ability to describe communities and rapidly assess anthropogenic impacts on biodiversity. Currently established molecular methods for biomonitoring rely heavily on classic metabarcoding utilising short reads, mostly through Illumina data. However, increasingly more studies use long-read sequencing technologies, such as Oxford Nanopore [...]
Herbarium specimens reveal long-term decline in pollination services since in the 1970s
Published: 2025-08-22
Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Environmental Monitoring, Natural Resources and Conservation, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
Anthropogenic change has resulted in pollinator decline and altered plant-pollinator interactions. This may drive widespread declines in pollination and reproductive success of plants, yet few datasets allow us to track changes in pollination services over time. Herbaria provide a unique opportunity to assess pollination services across broad spatial and temporal scales, and the associated [...]

I introduce the methodology of my nonproliferation research with quantum electrodynamics with the negative image equivalence with Charge-Coupled Devices. With the minimalist evidence gathering approach, I argue for a cosmologically relevant perspective in climate change that keeps an eye on the thermonuclear environment of outer space. I give a pilot narrative on the transcultural communication [...]
Characterising the structural complexity across major habitats of Tenerife, Spain
Published: 2025-06-13
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring, Life Sciences
Understanding biodiversity changes across ecosystems requires the consideration of various biodiversity dimensions, such as habitat structural complexity – the degree of heterogeneity in the distribution of plant material in three-dimensional space. Yet, its inclusion in long-term biodiversity monitoring on oceanic islands remains limited. Terrestrial laser scanning (TLS) can be used to quantify [...]
Mapping disturbance across California’s rapidly changing forests

Subjects: Environmental Monitoring, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability
Disturbances shape assemblages and spatial patterns of flora and fauna across the globe, and accurate disturbance mapping can aid conservation science and decision-making. However, mapping and differentiating among disturbance types using remote sensing is challenging, especially in forests with hidden subcanopy disturbances. On federal lands in the western US, wildfire, drought, and fuels [...]
National-scale datasets systematically underestimate vegetation recovery in Australian carbon farming projects
Published: 2025-06-11
