Mixed Bat-Hummingbird Pollination Assures Reproductive Success in a Highly Variable Upper Montane Species. [PDF]

open access: yesEcol Evol
We investigated the reproductive biology of Callianthe sellowiana, a high‐altitude Atlantic Forest species with traits associated with both bat and hummingbird pollination. Our results show that both pollinator groups are equally effective, and reproductive success is enhanced when both are present, highlighting the functional and temporal ...

Simultaneous Detection of Missing Amphibians and Their Fungal Pathogen in a Biodiversity Hotspot Using eDNA. [PDF]

open access: yesMol Ecol
ABSTRACT Since the 1970s, striking amphibian declines in population abundances and presumed extinctions have been recorded globally. The chytrid fungus Batrachochytrium dendrobatidis (Bd) is one of the key drivers of these declines. To investigate the potential role of Bd in the decline of Brazil's amphibians, we first used eDNA metabarcoding to survey

Long-Term Maintenance of Complex Chromosomal Inversion Polymorphism in <i>Drosophila mediopunctata</i>. [PDF]

open access: yesEcol Evol
It has become increasingly clear that natural selection favors haplotypes that draw functionally related genes together, often targeting mechanisms that control recombination rates. In this paper, we show that the long‐term maintenance of linkage disequilibrium between linked non‐overlapping chromosomal inversions in a Drosophila species may arise from

Montane diversification as a mechanism of speciation in neotropical butterflies. [PDF]

open access: yesEcol Evol
We investigated taxonomic boundaries between two sister montane species using genomic data. SNPs gathered using GBS indicated a strong isolation pattern consistent with morphology, separating all individuals of Actinote alalia from all populations of A. mantiqueira.

Functional assembly of tropical montane tree islands in the Atlantic Forest is shaped by stress tolerance, bamboo presence, and facilitation. [PDF]

open access: yesEcol Evol, 2021
We assessed functional traits of woody communities in tree islands and grasslands in the montane Atlantic forest. The woody communities are stress‐tolerant and respond to facilitation and bamboo‐encroached tree islands show reduced diversity. This has implications for tree island expansion and their vulnerability to climate change. Abstract Aims Amidst

Canine Leishmaniasis in Rio de Janeiro, Brazil (2000-2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis. [PDF]

open access: yesZoonoses Public Health
ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

Non-invasive sampling in Itatiaia National Park, Brazil: wild mammal parasite detection. [PDF]

open access: yesBMC Vet Res, 2020
Background Non-invasive sampling through faecal collection is one of the most cost-effective alternatives for monitoring of free-living wild mammals, as it provides information on animal taxonomy as well as the dynamics of the gastrointestinal parasites ...
