Post-Fire Predation Risk in the Black Cicada Tibicina quadrisignata

Fire
The background modification of ecosystems affected by fire can cause black or dark colours in animals to become adaptive, providing better protection against visually oriented predators.

3D Reconstruction Cost Function Algorithm Based on Stereo Matching in the Background of Digital Museums

IEEE Access, 2023
Stereo matching plays an important role in 3D reconstruction in the context of digital museums. At present, it has problems such as occlusion, weak texture, and discontinuous disparity, which restrict the development of binocular vision.

The influence of illumination and cast shadows on prey detectability by predators

Royal Society Open Science
Many species use camouflage to dissimulate their true form and avoid detection or recognition. In natural habitats, the three-dimensional structure of an organism’s body can present challenges for camouflage, as overhead illumination creates luminance ...

Differential frequency of autotomy in two colour morphs of the grasshopper Atractomorpha lata (Orthoptera: Pyrgomorphidae) on dense and sparse grass substrates

European Journal of Entomology
Background colour matching is considered highly effective in preventing the detection of an animal by visual predators. In a grasshopper species with green-brown polymorphism, a green morph on grass and a brown morph on bare ground or dead litter may be ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...

Scorpionfish adjust skin pattern contrast on different backgrounds

Ecology and Evolution
The two scorpionfish species Scorpaena maderensis and S. porcus are well camouflaged ambush predators that rapidly change body colouration to adjust to background colour in less than 1 min.

Generalist camouflage can be more successful than microhabitat specialisation in natural environments

BMC Ecology and Evolution, 2021
Background Crypsis by background-matching is a critical form of anti-predator defence for animals exposed to visual predators, but achieving effective camouflage in patchy and variable natural environments is not straightforward.

Measurable Residual Disease Monitoring During Treatment for Pediatric Acute Myeloid Leukemia in First Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...
