Morphometry of two cryptic tree frog species at their hybrid zone reveals neither intermediate nor transgressive morphotypes

open access: yesEcology and Evolution, 2022
Under incomplete reproductive isolation, secondary contact of diverged allopatric lineages may lead to the formation of hybrid zones that allow to study recombinants over several generations as excellent systems of genomic interactions resulting from the

Life History, Growth, and Reproductive Biology of Four Mobulid Species in the Bohol Sea, Philippines

open access: yesFrontiers in Marine Science, 2018
In light of the global decline of mobulid populations and the necessity for sustainable fisheries management, baseline data for population dynamics were collected from a targeted fishery in the Bohol Sea, Philippines.

Vertebrate palaeophysiology [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2020
Physiology is a functional branch of the biological sciences, searching for general rules by which explanatory hypotheses are tested using experimental procedures, whereas palaeontology is a historical science dealing with the study of unique events where conclusions are drawn from congruence among independent lines of evidence ...

How can the home range of the Lesser Kestrel be affected by a large civil infrastructure?

open access: yesAvian Research, 2019
Background The loss of traditional agropastoral systems, with the consequent reduction of foraging habitats and prey availability, is one of the main causes for the fast decline of Lesser Kestrel (Falco naumanni).

Genome elimination from the germline cells in diploid and triploid male water frogs Pelophylax esculentus

open access: yesFrontiers in Cell and Developmental Biology, 2022
Hybridogenesis is a hemiclonal reproductive strategy in diploid and triploid hybrids. Our study model is a frog P. esculentus (diploid RL and triploids RLL and RRL), a natural hybrid between P. lessonae (LL) and P. ridibundus (RR).

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

open access: yesFrontiers 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

Disentangling the Diversity of the Labeobarbus Taxa (Cypriniformes: Cyprinidae) from the Epulu Basin (DR Congo, Africa)

open access: yesDiversity, 2022
In an attempt to disentangle the complex taxonomy of the Labeobarbus species of the Epulu River, a right bank headwater affluent of the Aruwimi, Central Congo basin, a morphological study was undertaken on 221 specimens from the Epulu and 32 type ...

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

open access: yesEndangered 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.

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

open access: yesRoyal 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.
