Imperfect transparency and camouflage in glass frogs [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Camouflage patterns prevent detection and/or recognition by matching the background, disrupting edges, or mimicking particular background features. In variable habitats, however, a single pattern cannot match all available sites all of the time, and efficacy may therefore be reduced.

Frog tongue acts as muscle-powered adhesive tape [PDF]

open access: yesRoyal Society Open Science, 2015
Frogs are well known to capture fast-moving prey by flicking their sticky tongues out of the mouth. This tongue projection behaviour happens extremely fast which makes frog tongues a biological high-speed adhesive system.

First record of Vitreorana ritae (Anura, Centrolenidae) for southern Amazonia inferred from molecular, reproductive and acoustic evidence

open access: yesCaldasia, 2020
Frogs of the family Centrolenidae are adapted to live at high altitudes, and so it is not surprising that their greatest diversity is in the Andes mountain range.

Influence of open and closed windows on the vertical spread characteristics of fire

open access: yesEmergency Management Science and Technology, 2022
In order to systematically explain the spreading mechanism of vertical fire, Pyrosim software with fire dynamic modules is used to simulate the fire spreading characteristics in a five-storey residential apartment building.

Egg Clutch Survival under Prolonged Paternal Care in a Glass Frog, Hyalinobatrachium talamancae

open access: yesCopeia, 2020
Previous studies have reported egg attendance as the most common protective behavior among the Neotropical frog family Centrolenidae. However, research on the effect of parental care and other factors thought to affect offspring survival is still missing for a great number of species.

When the going gets rough – studying the effect of surface roughness on the adhesive abilities of tree frogs [PDF]

open access: yes, 2016
Tree frogs need to adhere to surfaces of various roughnesses in their natural habitats; these include bark, leaves and rocks. Rough surfaces can alter the effectiveness of their toe pads, due to factors such as a change of real contact area and abrasion

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

open access: yesJournal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.
