Evolutionary morphology of the lizard chemosensory system

open access: yesScientific Reports, 2017
Foraging mode plays a pivotal role in traditional reconstructions of squamate evolution. Transitions between modes are said to spark concerted changes in the morphology, physiology, behaviour, and life history of lizards.

Intrauterine growth restriction and its impact on intestinal morphophysiology throughout postnatal development in pigs

open access: yesScientific Reports, 2022
Intrauterine growth restriction (IUGR) compromises fetal development, leading to low birth weight, and predisposes to gastrointestinal disorders. Pigs that suffered IUGR present poor postnatal development, resulting in great economic losses to the ...

Small regions as key sources of traditional knowledge: a quantitative ethnobotanical survey in the central Balkans

open access: yesJournal of Ethnobiology and Ethnomedicine, 2022
Background Starting from the idea that unexplored areas may yield new and different ethnobotanical information, we performed a survey of traditional uses of plants in two neighboring districts situated in east Serbia (Bor and Aleksinac), both lacking in ...

Linking eye design with host symbiont relationships in pontoniine shrimps (crustacea, decapoda, palaemonidae) [PDF]

open access: yes, 2014
Symbiosis is prevalent in the marine environment with many studies examining the effects of such interactions between host and symbiont. Pontoniine shrimps are a group whose ecology is characterised by symbiotic interactions.

Progressive tracking: a novel procedure to facilitate manual digitization of videos

open access: yesBiology Open, 2020
Digitization of video recordings often requires the laborious procedure of manually clicking points of interest on individual video frames. Here, we present progressive tracking, a procedure that facilitates manual digitization of markerless videos.

On the methodology of feeding ecology in fish [PDF]

open access: yes, 2016
Feeding ecology explains predator’s preference to some preys over others in their habitat and their competitions thereof. The subject, as a functional and applied biology, is highly neglected, and in case of fish, a uniform and consistent ...

Environment-dependent prey capture in the Atlantic mudskipper (Periophthalmus barbarus)

open access: yesBiology Open, 2016
Few vertebrates capture prey in both the aquatic and the terrestrial environment due to the conflicting biophysical demands of feeding in water versus air.

Of hummingbirds and helicopters: Hovering costs, competitive ability, and foraging strategies [PDF]

open access: yes, 2004
Wing morphology and flight kinematics profoundly influence foraging costs and the overall behavioral ecology of hummingbirds. By analogy with helicopters, previous energetic studies have applied the momentum theory of aircraft propellers to estimate ...
