The food of coarse fish [PDF]

open access: yes, 1940
Remarkably little has been published on the feeding habits of the non-salmonid fishes of British fresh waters. The following report briefly summarizes the results obtained from the examination of the stomach contents of some 2,700 fish, belonging to 19 ...

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Vyhodnotenie malakofauny z náplavov Neresnice (stredné Slovensko) [PDF]

open access: yesMalacologica Bohemoslovaca, 2011
Sampling of flood debris deposits can be useful method in insufficiently surveyed areas. This sampling method also allows us to detect the presence of rare and endangered species in the study area.

Interactions between shorebirds and benthic invertebrates at Culbin Sands lagoon, NE Scotland: effects of avian predation on their prey community density and structure [PDF]

open access: yes, 2007
In the North Sea, during autumn-winter, intertidal flats often receive a massive influx of migratory shorebirds (wildfowl, waders and seabirds), which utilise the high prey densities that are available.

Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Malakofauna PR Hemže-Mýtkov [PDF]

open access: yesMalacologica Bohemoslovaca, 2009
Altogether, 78 mollusc species were recorded in the Hemže-Mýtkov Nature Reserve (East Bohemia, Czech Republic) during 2005–06. This locality harbours 32% of the total mollusc fauna of the Czech Republic at only 29 ha.

Characterization of the Myostracum Layers in Molluscs Reveals a Conservative Shell Structure

open access: yesFrontiers in Marine Science, 2022
Molluscs produce rigid shells to protect their soft bodies from predators and physiochemical violations. The soft tissues attach to shells via the myostracum layer (also called adductor muscle scar, AMS) which bears tremendous contract force and is of ...

Metals in the shell of Bathymodiolus azoricus from a hydrothermal vent site on the Mid-Atlantic Ridge [PDF]

open access: yes, 2007
Specimens of the mussel Bathymodiolus azoricus were collected from Menez Gwen, a relatively shallow (850 m) hydrothermal vent field on the Mid-Atlantic Ridge. Each bivalve shell (n = 21) was individually cleaned by selective chemical.
