High levels of species' extirpation in an urban environment-A case study from Berlin, Germany, covering 1700-2023. [PDF]

Ecol Evol
Our study compiled and analysed spatio‐temporal species' extirpation on a broad taxonomic coverage at the city scale. We revealed high number of extirpations, which are in the twenty‐firstcentury already comparable with previous centuries, and showed that cities might be suitable systems for studying species' extirpation processes due to their small ...

Integrating freshwater biodiversity data sources: Key challenges and opportunities

Freshwater Biology, Volume 68, Issue 9, Page 1479-1488, September 2023., 2023
Abstract In order to better quantify spatial and temporal patterns in freshwater biodiversity, and potential underlying drivers of change, we must utilise the increasingly broad range of data available on freshwater ecosystems. Statistical advances in the field of integrated modelling provide new opportunities to further our understanding through the ...

Pleistocene environments, climate, and human activity in Britain during Marine Isotope Stage 7: insights from Oak Tree Fields, Cerney Wick, Gloucestershire

Journal of Quaternary Science, Volume 38, Issue 6, Page 840-865, August 2023., 2023
ABSTRACT Investigations at Oak Tree Fields, Cerney Wick, Gloucestershire, in western England have revealed a sequence of fluvial deposits dating from Marine Oxygen Isotope Stage (MIS) 7 to 5. At the base of the sequence, a series of gravel and sand facies were deposited, initially as part of a meandering river.

Anticipating where are unknown aquatic insects in Europe to improve biodiversity conservation

Diversity and Distributions, Volume 29, Issue 8, Page 1021-1034, August 2023., 2023
Abstract Aim Understanding biodiversity patterns is crucial for prioritizing future conservation efforts and reducing the current rates of biodiversity loss. However, a large proportion of species remain undescribed (i.e. unknown biodiversity), hindering our ability to conduct this task.

Are patterns of sampling effort and completeness of inventories congruent? A test using databases for five insect taxa in the Iberian Peninsula

Insect Conservation and Diversity, Volume 15, Issue 4, Page 406-415, July 2022., 2022
The congruence in the spatial distribution of the sampling effort for five insect groups (butterflies, caddisflies, dung beetles, moths, and aquatic beetles) in the Iberian Peninsula was assessed. A general lack of reliable inventories is the rule as well as a general low geographical congruence in the completeness patterns of the different taxa. After

Diversity and Seasonality of Aquatic Beetles (Coleoptera) in Three Localities of the State of Tlaxcala, Central Mexico

Hydrobiology, 2023
Aquatic beetle diversity was compared between three study sites in the state of Tlaxcala, central Mexico: Stream 1 (San Ambrosio), stream 2 (San Tadeo), and a lake (Acuitlapilco). Sampling took place bimonthly during an annual cycle.
