Are the effects of an invasive crayfish on lake littoral macroinvertebrate communities consistent over time?

Knowledge and Management of Aquatic Ecosystems, 2016
Management of invasive species requires assessment of their effects on recipient ecosystems. However, impact assessment of invasive species commonly lacks a long-term perspective which can potentially lead to false conclusions.

Offspring Defensive Investment Covaries With Brood Value in a Female Cobweb Spider

Integrative Zoology, EarlyView.
We performed a thorough field investigation on the web architectures of Campanicola campanulata to research its cobweb architecture variation under the condition of whether it carried egg sacs, in order to test the theory of its brood value. Our results demonstrate that retreat construction in female cobweb spiders is modulated by brood value.

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

Fisheries Management and Ecology, EarlyView.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

Dispersal and coexistence of two non-native crayfish species (Pacifastacus leniusculus and Procambarus clarkii) in NE Portugal over a 10-year period

Knowledge and Management of Aquatic Ecosystems, 2011
NE Portugal is one of the most isolated and low populated regions of Western Europe. Recently, two American crayfish species reached this area: signal crayfish Pacifastacus leniusculus coming from Spain and red swamp crayfish Procambarus clarkii in its ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Acute toxicity of two pyrethroid insecticides for five non-indigenous crayfish species in Europe

Veterinární Medicína, 2019
Pyrethroid insecticides are highly toxic to many aquatic organisms. The aim of this study was to evaluate the toxicity of the commercial products Cyperkill 25 EC (active compound 250 g/l cypermethrin) and Decis Mega (active compound 50 g/l deltamethrin ...

Maturation of spinal motor control through developmental changes in ion currents

The Journal of Physiology, EarlyView.
Abstract figure legend Ion channels of spinal neurons have been shown to change during development in a wide range of species. These changes occur at specific stages of development. An important developmental process is the maturation of motor control by which the body acquires new movements or refines movements already present.

Characteristics and movement patterns of a recently established invasive Pacifastacus leniusculus population in the river Mura, Croatia

Knowledge and Management of Aquatic Ecosystems, 2011
The presence of the signal crayfish, Pacifastacus leniusculus, in waterbodies of Europe is of high concern due to its potentially major ecological impact on invaded ecosystems and native crayfish.
