Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

open access: yesConservation Biology, EarlyView.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Analiza tendencji rozwoju przewozów ładunków na śródlądowych drogach wodnych w Polsce

open access: yesPrace Naukowe Uniwersytetu Ekonomicznego we Wrocławiu, 2019
Examples from European countries show that the transport function of inland waterways is significant. In Poland, outlays on inland waterways are too small in relation to the needs.

An integrated approach to balance freshwater connectivity restoration and invasion risk

open access: yesConservation Biology, EarlyView.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

A bibliometric analysis of the development of autonomous ships in inland waterway transport

open access: yesFrontiers in Marine Science
Inland waterway transport (IWT) plays a critical role in global logistics, offering large-capacity, long-distance transport at a lower cost. Recently, the advent of autonomous ships has promised to revolutionize efficiency and sustainability within the ...

Assessment of ecosystem status in Mozambique and implications for environmental planning

open access: yesConservation Science and Practice, EarlyView.
We assess Mozambique's terrestrial ecosystems using the IUCN Red List of Ecosystems framework, showing that more than half of Mozambique's ecosystems are threatened, with impacts primarily concentrated in temperate subhumid grasslands and pyric tussock savannas.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

The prediction of wake wash in the towing tank [PDF]

open access: yes, 2008
The wash or ship-generated waves from high speed craft has become a common subject in research and development of marine transportation. Since some time now the wake wash of high speed craft has become a problem in particular on inland or confined ...

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany

open access: yesInsect Conservation and Diversity, EarlyView.
Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.
