Map and Archival Evidence of the Historical Avulsion of the Brahmaputra River

The Geographical Journal, EarlyView.
Short Abstract One of the world's great rivers, the Brahmaputra, avulsed—changed course—significantly sometime between the dates of 1765 and 1830. These are the dates of surveys by James Rennell (grey) and Richard Wilcox (black), both under the direction of the East India Company; no other surveys between these dates can refine the estimate of the ...

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

Insect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

Journal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...
