    Table for two: Diet composition differences of allopatric and sympatric populations of island geckos by Catarina J. Pinho, Bárbara Santos, Vanessa A. Mata, Ricardo J. Lopes, Maria M. Romeiras, Evandro P. Lopes, Paulo C. Alves, Brent C. Emerson, Raquel Vasconcelos

    Published 2025-01-01
    “…This is exemplified by the two endemic wall geckos, Tarentola gigas and Tarentola raziana, which occur in sympatry on Raso Islet, with the latter also occurring in allopatry on Santa Luzia Island, due to the human-mediated extinction of T. gigas. DNA metabarcoding of faecal pellets was used to compare the diets of both sympatric and allopatric populations. …”

    Pseudobarbus kubhekai sp. nov., a new redfin (Teleostei, Cyprinidae) from KwaZulu-Natal, South Africa by Fatah Zarei, Xiluva Mathebula, Albert Chakona

    Published 2025-01-01
    “…A recent phylogeographic analysis of the remnant populations of Pseudobarbus quathlambae from Lesotho and South Africa revealed the existence of three allopatrically distributed lineages: (i) one in eastern Lesotho, (ii) one in Mohale, central Lesotho, and (iii) a third lineage in the Umzimkhulu (= Mzimkhulu) River, KwaZulu-Natal, adjacent to the Mkhomazana River (type locality), where the species has gone extinct. The present study provides morphological and osteological evidence corroborating the distinctiveness of the Umzimkhulu River population from all other populations (extant and extinct) of P. quathlambae, supporting their recognition as distinct species. …”

    The first neuroanatomical study of a marine pleurodire (the large Paleocene bothremydid Azzabaremys moragjonesi) reveals convergences with other clades of pelagic turtles by Marcos Martín-Jiménez, Adán Pérez-García

    Published 2025-01-01
    “…Thus, aspects such as the position of the geniculate ganglion into the canalis cavernosus, the absence of an anterior vidian canal piercing the pterygoid, and the possession of wide semicircular canals of the endosseous labyrinth, as well as the possible presence of enlarged lacrimal glands, are recognized here as convergent modifications developed in Cryptodira, extinct clades with uncertain affiliations, and Pleurodira in response to adaptation to marine environments.…”

    Global Dynamics of a Prey-Predator Model with Antipredator Behavior and Two Predators by Chentong Li, Yingying Zhang, Jinhu Xu, Yicang Zhou

    Published 2019-01-01
    “…Through analyzing the global dynamics, we find that there exist some values of the parameters such that one of the predators can be driven into being extinct by another. Furthermore, the coexistence of the three species is investigated which shows that the antipredator behavior makes the species coexist by periodic oscillation. …”

    Global stability and uniform persistence of the reaction-convection-diffusion cholera epidemic model by Kazuo Yamazaki, Xueying Wang

    Published 2017-03-01
    “…We study the global stability issue of the reaction-convection-diffusion cholera epidemic PDE model and show that the basic reproduction number serves as a threshold parameter that predicts whether cholera will persist or become globally extinct. Specifically, when the basic reproduction number is beneath one, we show that the disease-free-equilibrium is globally attractive. …”
