Leucism in Akodon affinis (Allen, 1912) (Rodentia: Cricetidae) [PDF]
Therya, 2017 Leucism is a condition where animals show a loss of pigments on certain parts of their skin, without affecting soft tissue, a condition that has been poorly reported for Neotropical rodents. Therefore, our goal was to report leucism for Akodon affinis, an endemic species from Colombia, and to analyze the pattern of leucism prevalence in different ...

Anomalous coloration in European pine marten Martes martes in Elba Island, Central Italy
Ecology and Evolution, 2022 Evidence of abnormal coloration in wild animals provides useful information to better understand its adaptive function and its impact on survival. For this reason, we need to know the frequency and distribution of these abnormal phenotypes in wild ...

Leucism and albinism in the rear-fanged snakes Tachymenis chilensis chilensis (Schlegel, 1837) and Tachymenis chilensis coronellina Werner, 1898 (Serpentes, Dipsadidae) [PDF]
Herpetozoa, 2021 Herein, we report the first observation of two different coloration patterns in Chilean snakes. Based on the alteration of wild coloration patterns, a juvenile specimen of Tachymenis chilensis coronellina Werner, 1898 was diagnosed with albinism and a ...

Camera trap records of leucistic Eurasian badgers (Meles meles) in central Norway
Ecology and Evolution, 2021 Coat coloration plays an important role in communication, camouflage, and sexual selection in animals. Genetic mutations can lead to anomalous colorations such as melanism and leucism, where animals appear, respectively, darker or lighter than normal ...

Systematically Engineering for Efficient Production of 3‐Methyl‐1‐Butanol in Escherichia coli
Advanced Science, Volume 13, Issue 21, 13 April 2026.An integrated metabolic engineering strategy was established for high‐level 3‐methyl‐1‐butanol biosynthesis in Escherichia coli. Molecular dynamics‐guided semi‐rational engineering of dihydroxyacid dehydratase uncovered and relieved key catalytic bottlenecks, while adaptive laboratory evolution enhanced strain robustness.
