Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

Is interlocked grain an adaptive trait for tropical tree species in rainforest? [PDF]

, 2009
Many trees in tropical rain forest exhibit interlocked grain. This phenomenon was observed, using a splitting method, on 10 trees from different genera in French Guiana. There were rather strong variations between and within trees. Different indexes were

Catherine de' Medici and the Forest of Orleans: Queenly Participation in Early Modern French Forest Management

Renaissance Studies, EarlyView.
Abstract This essay demonstrates how a gender‐informed, more‐than‐human lens can provide new ways to analyse how the role of a queen in forestry management was conceptualised by sixteenth‐century professional men. It explores these ideas as they are presented in a work published by Guillaume Martin, Lieutenant General of the forests and waterways of ...

H_2 formation and excitation in the Stephan's Quintet galaxy-wide collision [PDF]

, 2009
Context. The Spitzer Space Telescope has detected a powerful (L_(H_2) ~ 10^(41) erg s^(-1)) mid-infrared H_2 emission towards the galaxy-wide collision in the Stephan's Quintet (henceforth SQ) galaxy group. This discovery was followed by the detection of

Efficient ortho-para conversion of H2 on interstellar grain surfaces

, 2016
Context: Fast surface conversion between ortho- and para-H2 has been observed in laboratory studies, and this mechanism has been proposed to play a role in the control of the ortho-para ratio in the interstellar medium.
