Nitric oxide synthases in mammals.
Biochemical Journal, 1994 Nitric oxide is an inorganic free radical gas, of formula *N=O (abbreviated as NO). The discovery in 1987/88 that vascular endothelial cells are able to synthesize NO from L-arginine as a transcellular signal [1-4] was initially received by most ...

Animal Biotelemetry, 2023 Background Due to their Arctic habitat and elusive nature, little is known about the narwhal (Monodon monoceros) and its foraging behaviour. Understanding its ability to catch prey is essential for understanding its ecological role, but also to assess ...

The Mammals of Kilimanjaro [PDF]
Journal of East African Natural History, 1995 (Uploaded by Plazi for the Bat Literature Project) This paper presents an up to date account of 154 mammal species recorded on Mount Kilimanjaro, Tanzania, and the surrounding area, from 1883 to the present, when 128 species are known to occur. Old records are reviewed and several new records added, while four recorded species have been excluded.

The metabolic origins of big size in aquatic mammals [PDF]
arXiv, 2022 The group of large aquatic mammals has representatives being the largest living beings on earth, surpassing the weight and size of dinosaurs. In this paper, we present some empirical evidence and a mathematical model to argue that fat accumulation in marine mammals triggers a series of metabolic events that result in these animals' increased size.

Mammal endemism In Italy: A review [PDF]
, 2018 Although there are various checklists of Italian mammals, there is not yet a synthesis of those mammals that are endemic to Italy. Therefore, we provide for the first time a detailed review on Italian mammal endemic species including endemic taxa ...

The role of transposable elements in the evolution of non-mammalian vertebrates and invertebrates [PDF]
Genome Biology 2010, 11:R59, 2010 Background: Transposable elements (TEs) have played an important role in the diversification and enrichment of mammalian transcriptomes through various mechanisms such as exonization and intronization (the birth of new exons/introns from previously intronic/exonic sequences, respectively), and insertion into first and last exons.

American Zoologist, 1967 This paper centers on selected—and particularly, little recognized— problems in mammalian olfaction: (1) With certain exceptions the spacing of the external nares in most mammals does not favor orientation in an odor gradient by simultaneous comparisons of odor intensities (tropotaxis).

Central and peripheral circadian clocks in mammals.
Annual Review of Neuroscience, 2012 The circadian system of mammals is composed of a hierarchy of oscillators that function at the cellular, tissue, and systems levels. A common molecular mechanism underlies the cell-autonomous circadian oscillator throughout the body, yet this clock ...
