Shell characterization of the youngest valid species of the European Eocene genus Neochelys (Pleurodira, Podocnemididae): The Spanish Bartonian Neochelys salmanticensis

The Anatomical Record, Volume 308, Issue 6, Page 1553-1572, June 2025.
Abstract The freshwater pleurodiran turtle Neochelys is the best‐represented member of Podocnemididae in the European record, being known by eight Eocene species. The youngest of them is the Bartonian (middle Eocene) Neochelys salmanticensis, from the Duero Basin (Salamanca Province, Central Spain).

A bothremydid turtle (Pleurodira) from the middle Cenomanian of Vale de Figueira (Belas, Portugal)

The Anatomical Record, Volume 308, Issue 6, Page 1573-1579, June 2025.
Abstract An unpublished turtle shell from the middle Cenomanian of Vale de Figueira, near Belas (Lisbon District, Portugal), is recognized by us as collected in 1880 under the direction of Carlos Ribeiro. No turtle remains from that region had so far been figured, described or discussed from a systematic point of view.

Differential xylem phytohormone export from dry and wet roots during partial rootzone drying is independent of shoot‐to‐root transport in soybean

Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.
Abstract Different phytohormones can act as root‐to‐shoot signalling molecules in response to soil drying. Recent findings suggest that root ABA levels are predominantly leaf‐sourced and not locally synthesized, thus, ABA exported from the roots in the xylem is mostly recycled from the shoot.
