The History, Present Condition, and Future of the Molluscan Fisheries of North and Central American and Europe: Volume 1, Atlantic and Gulf Coasts [PDF]

open access: yes, 1997
This three-volume monograph represents the first major attempt in over a century to provide, on regional bases, broad surveys of the history, present condition, and future of the important shellfisheries of North and Central America and Europe.

Acoustic indices are not useful for biodiversity research

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Biodiversity assessment using passive acoustic monitoring has historically been challenging due to the limited availability of multi‐species acoustic detectors. In this context, acoustic indices were introduced as an alternative way to represent species diversity in acoustic datasets.

CheckEM: An open‐source toolkit for standardising, cleaning and visualising stereo‐video fish survey data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Effective research and monitoring requires accurate, interoperable and representative data. Stereo‐video based methods are commonly used to survey fish and are rapidly expanding globally due to their cost‐effectiveness, ability to provide accurate body size measurements, non‐destructive approach and capacity to create permanent data records ...

Managing the Threat of Subsidized Predators for a Threatened Shorebird

open access: yesAnimal Conservation, EarlyView.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

open access: yesBoreas, EarlyView.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.

Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

open access: yesConservation Biology, EarlyView.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Unraveling the risk of dredging on river bars for mineral sand mining: an engineering geological approach

open access: yesDiscover Geoscience
Sand mining using dredging technology from channel bars is a common technique worldwide. To minimize adverse effects of dredging, geo-engineering nature of the soil should be evaluated before mining.

Common Law Jurisprudence on Public Vessel Status in the United States: Annotated Cases [PDF]

open access: yes, 2017
This document provides an overview of the facts and disposition of federal cases interpreting whether vessels are “public vessels” under U.S. admiralty law. This document is a supplement to Status of the U.S.

The value of saltbush revegetation for biodiversity in a highly fragmented landscape

open access: yesConservation Science and Practice, EarlyView.
Saltbush revegetation provides limited value for faunal biodiversity. Saltbush has the lowest species richness and diversity of ants, spiders, and birds. Remnant habitats continue to provide the most important habitats for native species. Abstract Secondary salinization is a significant global issue affecting up to 1 billion hectares of land, impacting
