A new method for identifying vertebrates using only their mitochondrial DNA [PDF]

open access: yesarXiv, 2009
A new method for determining whether or not a mitrochondrial DNA (mtDNA) sequence belongs to a vertebrate is described and tested. This method only needs the mtDNA sequence of the organism in question, and unlike alignment based methods, it does not require it to be compared with anything else. The method is tested on all 1877 mtDNA sequences that were

Integration of Genetic and Phenotypic Data in 48 Lineages of Philippine Birds Shows Heterogeneous Divergence Processes and Numerous Cryptic Species. [PDF]

open access: yesPLoS ONE, 2016
The Philippine Islands are one of the most biologically diverse archipelagoes in the world. Current taxonomy, however, may underestimate levels of avian diversity and endemism in these islands.

Revision of nucleotide substitution rate in mtDNA control region of white sturgeon Acipenser transmontanus (Acipenseridae) [PDF]

open access: yesarXiv, 2017
The raw data from study of variation of D-loop mtDNA of white sturgeon Acipenser transmontanus (Mol. Biol. Evol. 1993. 10: 326-341) was re-analyzed. Re-calculated nucleotide substitution rate ({\mu}) was 0.782-0.939 x 10-7 substitutions/site/year/lineage, which was 1.4 times less than the estimate given in above-mentioned publication.

Pleistocene phylogeographic effects on avian populations and the speciation process. [PDF]

open access: yes, 1998
Pleistocene biogeographic events have traditionally been ascribed a major role in promoting speciations and in sculpting the present-day diversity and distributions of vertebrate taxa.

Mosquito‐derived ingested DNA as a tool for monitoring terrestrial vertebrates within a peri‐urban environment

open access: yesEcosphere, Volume 16, Issue 1, January 2025.
Abstract Global biodiversity is declining at an alarming rate. Consequently, there is a pivotal need to determine the occurrences and distributions of threatened species. Monitoring and detection approaches are traditionally reliant on capture (traps and cameras), as well as observations.

Molecular techniques reveal cryptic life history and demographic processes of a critically endangered marine turtle [PDF]

open access: yes, 2014
The concept of ‘effective population size’ (Ne), which quantifies how quickly a population will lose genetic variability, is one of the most important contributions of theoretical evolutionary biology to practical conservation management.

Genomic Introgression Between Critically Endangered and Stable Species of Darwin's Tree Finches on the Galapagos Islands

open access: yesEvolutionary Applications, Volume 18, Issue 1, January 2025.
ABSTRACT Natural hybridisation among rare or endangered species and stable congenerics is increasingly topical for the conservation of species‐level diversity under anthropogenic impacts. Evidence for beneficial genes being introgressed into or selected for in hybrids raises concurrent questions about its evolutionary significance.

Population structure of avian malaria parasites

open access: yesEcology and Evolution, 2019
The geographic distribution of genetic diversity in malaria parasite populations (Apicomplexa: Haemosporida) presumably influences local patterns of virulence and the evolution of host‐resistance, but little is known about population genetic structure in

Phylogeography of the Red‐Headed Manakin Supports the River‐Refuge Hypothesis

open access: yesJournal of Biogeography, Volume 52, Issue 1, Page 92-107, January 2025.
ABSTRACT Aim The Amazon rainforest is one of the most biodiverse regions on earth, but our understanding of the processes that have shaped its patterns of diversity remains incomplete. One hypothesis for Amazonian speciation is the river‐refuge hypothesis, which suggests that retraction of forests away from the periphery of Amazonia, where rivers are ...
