Co-occurrence of neurofibromatosis type 1 and optic nerve gliomas with autosomal dominant polycystic kidney disease type 2. [PDF]

Mol Genet Genomic Med, 2020
We report an Autosomal dominant polycystic kidney disease (ADPKD) male belonging to a family of several affected members in three generations associated with neurofibromatosis type 1 (NF1) ) and optic pathway gliomas. Conclusión: this is the first reported case of concurrence of a truncated NF1 mutation with optic pathway gliomas and a nonsense PKD2 ...

Effects of landscape fragmentation on floodplain fishes as revealed by species-habitat networks. [PDF]

Conserv Biol
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]

Mol Ecol
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Laboulbeniales hyperparasites (Fungi, Ascomycota) of bat flies: Independent origins and host associations. [PDF]

Ecol Evol, 2018
In this article, we focus on a fascinating hyperparasitic study system. More specifically, we study the ectoparasitic fungi that are associated with the flies that are bloodsucking ectoparasites of bats (Mammalia and Chiroptera). We make an important contribution to the field by (a) applying new methodologies for DNA extraction (including a whole ...

Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

Ecology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna

Conservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021
Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).
