Preservation biases in the fossil record distort species ecological niche and distribution models

Ecography, Volume 2026, Issue 3, March 2026.
Ecological niche models (ENMs) increasingly leverage the fossil record to understand species' environmental associations and predict their geographic distributions. However, fossils do not occur uniformly through time and space, which can compromise the robustness of ENMs and thus affect ecological conclusions. Here, we assessed how preservation biases

The Neolithic Site of Piano dei Cardoni in the Island of Ustica (Italy): Minero‐Petrographic and Chemical Characterization of the Ceramic Finds and Clayey Raw Materials

Geoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

Shell‐Dense Island Off Culasawani, Vanua Levu Island, Fiji: Midden or Muddle?

Geoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT Investigations of a 3000 m2 shell‐dense island surrounded by mangroves off the coast of Culasawani, a very lightly inhabited part of northern Vanua Levu Island in Fiji, suggest it is likely to be a ‘midden island’ rather than a (tsunami) wave deposit.

Dust Deposition and Loess Accretion in New Zealand's South Island: Examining Links between Cold‐Climate Processes and Dust Production

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
We compared temporal variability in dust and loess accretion in New Zealand's South Island with glacial activity in the central Southern Alps, considered the main mechanism of silt production, in (i) a proximal loess deposit at Barrhill, Rakaia River and (ii) a distal dust record from a peat mire in Central Otago.

Rangitīkei River Terraces Formed During the Otira Glaciation: Lithostratigraphic Type Sections, Review and Conceptual Model

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Rangitīkei Valley in the lower North Island of New Zealand contains flights of river terraces that are influenced by changes in sediment supply, stream power and base level associated with Quaternary climate events over the last ∼350 thousand years.
