Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

open access: yesWildlife Biology, EarlyView.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.

Spatial ecology of the critically endangered Fijian crested iguana, Brachylophus vitiensis, in an extremely dense population: implications for conservation

open access: yes, 2015
The Critically Endangered Fijian crested iguana, Brachylophus vitiensis, occurs at extreme density at only one location, with estimates of >10,000 iguanas living on the 70 hectare island of Yadua Taba in Fiji. We conducted a mark and recapture study over

Don’t Demean “Invasives”: Conservation and Wrongful Species Discrimination [PDF]

open access: yes, 2019
It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Experimental infestation with the immatures of Amblyomma dissimile Koch, 1844 (Acari: Ixodidae) on Tropidurus torquatus (Lacertilia: Iguanidae) and Oryctolagus cuniculus Infestação experimental com as fases imaturas de Amblyomma dissimile Koch, 1844 (Acari: Ixodidae) em Tropidurus torquatus (Lacertilia: Iguanidae) e Oryctolagus cuniculus

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2004
Larvas provenientes de duas fêmeas de Amblyomma dissimile Koch, 1844 (Acari: Ixodidae), naturalmente ingurgitadas em uma iguana (Iguana iguana) e provenientes do Estado do Mato Grosso, foram utilizadas na infestação experimental de lagartos da espécie ...

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Muscular anatomy of the pectoral girdle and forelimb of Iguana i. iguana (Squamata: Iguanidae)

open access: yesBioscience Journal, 2017
Green iguana has arboreal and terrestrial habits. It is widely distributed in Central and South America, inhabiting several biomes in Brazil. Some researches were focused on this species, however, morphological information are still limited.
