ABSTRACT Freshwater mussels are in decline worldwide, and their conservation is limited by a lack of understanding of species ecology and biology, particularly in the southern hemisphere. Hyridella narracanensis is a threatened species which is co‐distributed with a more abundant congener, H. drapeta.

Gaia: Complex systems prediction for time to adapt to climate shocks
Abstract Earth's climate has undergone significant fluctuations in the geologic past, while the sun's radiation continues to increase, yet has always returned to conditions highly favorable to life. Thus, the biosphere overall appears able to cancel effects of external trends as well as provide negative feedback to internal fluctuations.

CONTRIBUTION TO THE THEORY OF CELL COLLAPSE IN WOOD: INVESTIGATIONS WITH EUCALYPTUS REGNANS
Total collapse is considered as the sum of "liquid tension collapse" and "stress collapse". An equation is derived giving total collapse as a linear function of wood temperature and, to a smaller extent, of collapse-free shrinkage.

Abstract Termites are important ecosystem engineers in many ecosystems globally. Hence, surveys of termite species composition, abundance and activity can be important for understanding ecosystem function—especially in biomes where they tend to be abundant, such as tropical savannas. However, comprehensively surveying termites can be challenging due to

Weak link or strong foundation? Vulnerability of fine root networks and stems to xylem embolism
Summary Resolving the position of roots in the whole‐plant hierarchy of drought‐induced xylem embolism resistance is fundamental for predicting when species become isolated from soil water resources. Published research generally suggests that roots are the most vulnerable organ of the plant vascular system, although estimates vary significantly ...
