Nocturnality is a key evolutionary innovation of mammals that enables mammals to occupy relatively empty nocturnal niches. Invasion of ancestral mammals into nocturnality has long been inferred from the phylogenetic relationships of crown Mammalia, which is primarily nocturnal, and crown Reptilia, which is primarily diurnal, although molecular evidence for this is lacking. Here we used phylogen...

Palaeobiogeographic reconstructions are underpinned by phylogenies, divergence times and ancestral area reconstructions, which together yield ancestral area chronograms that provide a basis for proposing and testing hypotheses of dispersal and vicariance. Methods for area coding include multi-state coding with a single character, binary coding with multiple characters and string coding. Ancestr...

Laurasiatheria is one of the richest and most diverse superorders of placental mammals. Because this group had a rapid evolutionary radiation, the phylogenetic relationships among the six orders of Laurasiatheria remain a subject of heated debate and several issues related to its phylogeny remain open. Reconstructing the true phylogenetic relationships of Laurasiatheria is a significant case st...

Acid phosphatases (AcPs) are known to provide phosphate to tissues that have high energy requirements, especially during development, growth and maturation. During spermatogenesis AcP activity is manifested in heterophagous lysosomes of Sertoli cells. This phagocytic function appears to be hormone-independent. We examined the expression pattern of AcP during the reproductive period of four spec...

The Nycteribiidae is a group of ectoparasitic and hematophagous flies associated with bats barely known in Colombia. revision previously collected material additional fieldwork through various regions Colombia let us to identify fly species their bats. Particularly, this the first record Basilia tiptoni Guimarães, 1966, for Colombia, on bat Gardnerycteris keenani (Handley, 1960) (Mammalia: Chir...

We present a haplotype resolved, diploid genome assembly from male Meles meles (European badger; Chordata; Mammalia; Carnivora; Mustelidae) using the trio binning approach. The sequence is 2,739 megabases in span. majority of (95.16%) scaffolded into 23 chromosomal pseudomolecules with X and Y sex chromosomes assembled. complete mitochondrial was also assembled 1...
