Morphology of the First Zoeal Stage of the Shrimp Typton distinctus Chace, 1972: The Second for the Genus Typton O.G. Costa, 1844 After 100 Years

open access: yesActa Zoologica, EarlyView.
ABSTRACT The marine shrimp of the genus Typton are widely distributed, known to be associated with sessile organisms such as sponges. Information about this genus is limited, highlighting the scarcity of important features in its biology, including larval forms.

Excitatory local interneurons enhance tuning of sensory information.

open access: yesPLoS Computational Biology, 2012
Neurons in the insect antennal lobe represent odors as spatiotemporal patterns of activity that unfold over multiple time scales. As these patterns unspool they decrease the overlap between odor representations and thereby increase the ability of the ...

Laboratory Biology, Immature and Adult Morphology of Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae), Parasitoids of Drosophila Flies

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study investigates the laboratory biology and morphology of the parasitoid Trichopria drosophilae, which targets Drosophila flies, including the invasive Drosophila suzukii. Key findings include a detailed description of the parasitoid's egg, three larval instars, and pupal stage, as well as unique behaviors such as siblicide and encapsulation in ...

Synaptic organization of the Drosophila antennal lobe and its regulation by the Teneurins

open access: yeseLife, 2014
Understanding information flow through neuronal circuits requires knowledge of their synaptic organization. In this study, we utilized fluorescent pre- and postsynaptic markers to map synaptic organization in the Drosophila antennal lobe, the first ...

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

open access: yesJournal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

open access: yesNew Phytologist, EarlyView.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Fast and robust learning by reinforcement signals: explorations in the insect brain [PDF]

open access: yes, 2009
We propose a model for pattern recognition in the insect brain. Departing from a well-known body of knowledge about the insect brain, we investigate which of the potentially present features may be useful to learn input patterns rapidly and in a stable ...
