Interplay Between River Formation and Historical Climatic Changes Drove Diversification of the Thamnomanes caesius and T. schistogynus (Passeriformes, Thamnophilidae) Species Complex Across Amazonian and Atlantic Forests

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 555-567, July 2026.
ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Disentangling Leucocytozoon parasite diversity in the neotropics: Descriptions of two new species and shortcomings of molecular diagnostics for leucocytozoids

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2019
Avian communities from South America harbor an extraordinary diversity of Leucocytozoon species (Haemosporida, Leucocytozoidae). Here, of 890 birds sampled, 10 (1.2%) were infected with Leucocytozoon parasites. Among them, two new species were discovered

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,

Characterization of the mitogenomes for two sympatric breeding species in Recurvirostridae (Charadriiformes) and their phylogenetic implications

open access: yesMitochondrial DNA. Part B. Resources, 2017
Recurvirostridae is a family of Charadriiformes that displays an amazing amount of characterization at evolutionary level. The mitogenomes of Himantopus himantopus and Recurvirostra avosetta are 17,378 bp and 16,856 bp in size, respectively.

Molecular phylogenetics and mitogenomics of three avian dicrocoeliids (Digenea: Dicrocoeliidae) and comparison with mammalian dicrocoeliids

open access: yesParasites & Vectors, 2020
Background The Dicrocoeliidae are digenetic trematodes mostly parasitic in the bile ducts and gall bladder of various avian and mammalian hosts. Until recently their systematics was based on morphological data only.

An updated checklist of Culicoides Latreille, 1809 biting midges from the highlands of eastern Democratic Republic of the Congo Une liste mise à jour des moucherons piqueurs de Culicoides Latreille, 1809 des hautes terres de l'est de la République démocratique du Congo

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 2, Page 422-440, June 2026.
The highlands of eastern Democratic Republic of the Congo (DRC) are home to critically endangered eastern gorillas (Gorilla beringei). Climate change could increase the abundance and distribution of Culicoides‐borne diseases. We utilized morphological and molecular techniques to identify Culicoides spp.
