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 ...

The intrinsic B-mode polarisation of the cosmic microwave background [PDF]

, 2014
. We estimate the B-polarisation induced in the Cosmic Microwave Background by the non-linear evolution of density perturbations. Using the second-order Boltzmann code SONG, our analysis incorporates, for the first time, all physical effects at ...

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 ...

Exploiting general-purpose background knowledge for automated schema matching [PDF]

, 2022
The schema matching task is an integral part of the data integration process. It is usually the first step in integrating data. Schema matching is typically very complex and time-consuming.

Seasonal plasticity in anti‐predatory strategies: Matching of color and color preference for effective crypsis

Evolution Letters, 2019
Effective anti‐predatory strategies typically require matching appearance and behavior in prey, and there are many compelling examples of behavioral repertoires that enhance the effectiveness of morphological defenses. When protective adult morphology is

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

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.

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

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.
