Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

A Normalization-Calibration Model for Multi-Source Ground-Based FPAR Observations in Mountainous Forests

Remote Sensing
The fraction of absorbed photosynthetically active radiation (FPAR) is a key physiological variable for characterizing vegetation structure and associated matter and energy exchange processes.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Validation of the vertical canopy cover profile products derived from GEDI over selected forest sites

Science of Remote Sensing
Canopy cover (CC) quantifies the proportion of canopy materials projected vertically onto the ground surface. CC is a crucial canopy structural variable and is commonly used in many ecological and climatic models.

AlpIce‐1: a database of geochronological and geomorphological constraints on Alps‐wide palaeoglacier fluctuations between the Last Glacial Maximum and the Holocene

Boreas, EarlyView.
The AlpIce‐1 database is the first compilation of published geomorphological and geochronological markers constraining build‐up, culmination and decay of glaciers from the Last Glacial Maximum through the Holocene across the entire European Alps. AlpIce‐1 integrates more than 4200 surface‐exposure and radiocarbon ages, homogenized, quality controlled ...

High‐Gloss SVBRDF Capture Using Bounce Light

Computer Graphics Forum, EarlyView.
Abstract Reflectance capture aims at the visual reproduction of an object under varying illumination. Past works differ substantially in their experimental overhead, from single‐ or few‐image approaches, that employ significant (often learned) priors at the expense of biased reconstructions, to more accurate approaches that tend to be time‐consuming ...

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

Ibis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...
