Development of the early axon scaffold in the rostral brain of the small spotted cat shark (Scyliorhinus canicula) embryo [PDF]

, 2014
International audienceThe cat shark is increasingly used as a model for Chondrichthyes, an evolutionarily important sister group of the bony vertebrates that include teleosts and tetrapods.

Long-Term Photo-Identification Reveals the Population Dynamics and Strong Site Fidelity of Adult Whale Sharks to the Coastal Waters of Donsol, Philippines

Frontiers in Marine Science, 2018
Donsol in the Philippines is the longest running community-based whale shark (Rhincodon typus) ecotourism site in Southeast Asia, with peak visitation in 2012 of over 27,000 tourists. In order to understand this aggregation and the importance of the area

In-water methods reveal population dynamics of a green turtle Chelonia mydas foraging aggregation in the Philippines

Endangered Species Research, 2019
The green turtle Chelonia mydas is an Endangered species that forms aggregations at neritic foraging sites where juveniles spend, in some cases, over a decade before moving to adult- or subadult-dominated foraging sites.

A Mutual Information Based Sequence Distance For Vertebrate Phylogeny Using Complete Mitochondrial Genomes [PDF]

, 2007
Traditional sequence distances require alignment. A new mutual information based sequence distance without alignment is defined in this paper. This distance is based on compositional vectors of DNA sequences or protein sequences from complete genomes ...

Revisiting the Baltimore–Bullock's Oriole hybrid zone reveals changing plumage colour in Bullock's Orioles

Royal Society Open Science, 2022
Hybrid zones are dynamic areas where populations of two or more interbreeding species may change through an influx of novel genetic material resulting from hybridization or selection on standing genetic variation.

Monoaminergic modulation of photoreception in ascidian:evidence for a proto-hypothalamo-retinal territory [PDF]

, 2012
Background : The retina of craniates/vertebrates has been proposed to derive from a photoreceptor prosencephalic territory in ancestral chordates, but the evolutionary origin of the different cell types making the retina is disputed.

Tubbataha Reefs Natural Park: the first comprehensive elasmobranch assessment reveals global hotspot for reef sharks

Journal of Asia-Pacific Biodiversity, 2019
Elasmobranchs are experiencing population declines worldwide because of anthropogenic stressors. Marine protected areas (MPAs) have been shown to benefit mesopredatory species of shark.

The evolutionary development of the renin angiotensin aldosterone system and its importance for the survival of the human species

Arterial Hypertension, 2021
Kidneys produce a number of substances that affect intrarenal blood circulation; however, the key system that regulates blood flow in both general and local circulation (including the renal circulation) is the renin-angiotensinaldosterone system (RAAS ...

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.
