Escallonia (Escalloniaceae) is a New World genus of c. 39 species distributed mainly in the South American highlands. Plastid DNA sequence data from the intergenic spacers trnS-trnG and 3′ trnV-ndhC and the ndhF gene f...

The accurate identification of taxa of Aotus is essential for 1) the development of precise biomedical assays, 2) the determination of potential illegal traffic of this genus, and 3) conservation. Although many studies h...

In plant leaves, resource use follows a trade-off between rapid resource capture and conservative storage. This “worldwide leaf economics spectrum” consists of a suite of intercorrelated leaf traits, among which leaf...

The nominal species Oligoryzomys flavescens (yellow pygmy rice rat) appears in different phylogenetic reconstructions as paraphyletic, forming a complex together with Oligoryzomys fornesi (Fornes' pygmy rice rat) or Olig...

With the advent of molecular phylogenetics, Perrie & al. (in Austral. Syst. Bot. 28: 256–264. 2015), Schneider & al. (in Perspect. Pl. Ecol. Evol. Syst. 18: 70–78. 2016), Shang & al. (in Molec. Phylogen. Evol. 127: 4...

The Drawida japonica (Michaelsen, 1892) species complex is widely distributed across Asia, yet its taxonomy remains challenging due to morphological conservatism and cryptic diversity. Using an integrative taxonomic appr...

After almost 70 years of stability following publication of Andersen's (1912) monograph on the group, the systematics of megachiropteran bats (Chiroptera: Pteropodidae) was thrown into flux with the advent of molecular p...

ABSTRACT Enteric diseases of bacterial origin are frequent in the pig industry, of particular notoriety are the colibacillosis that mainly affect piglets and cause great damage to the swine industry worldwide. The aim of...

The inference of phylogenetic hypotheses from landmark data has been questioned during the last two decades. Besides theoretical concerns, one of the limitations pointed out for the use of landmark data in phylogenetics ...

Abstract Zoonoses are among the greatest threats to human health, with many zoonotic pathogens believed to have emerged following the Neolithic transition. Palaeomicrobiological investigations of the zooarchaeological re...

Liolaemus is a diverse genus of lizards, subdivided into two subgenera: Liolaemus (sensu stricto) and Eulaemus, distributed mainly in Chile and Argentina. The L. elongatus-kriegi complex is the most diverse group within ...

Las relaciones filogenéticas entre las especies del género Pseudopaludicola son analizadas en base a caracteres externos y osteológicos. Se estudiaron once especies de Physalaemus las que fueron empleadas como grupo e...

ABSTRACT Non-Helicobacter pylori Helicobacters(NHPH) account for causing moderate and severe gastritis in humans. Moreover, they have already been documented in the oral cavity of feline animals. The current study aims t...

Several comprehensive studies have greatly contributed to the clarification of Odonata phylogeny, paying special attention to the damselflies (Zygoptera). Nearly half of the species of Zygoptera are included in the famil...

This paper describes how prior uncertainty of the homology of different parts of organisms, and therefore of the characters contained in those parts, can be analysed by recoding the set of characters into a complex chara...

Anthropogenic climate change is one of the main threats to global biodiversity, with amphibians being among the most vulnerable vertebrate groups. In this context, the IUCN currently lists 69 species of Neotropical glass...

Abstract Fasciolosis is a foodborne anthropozoonotic disease caused by Fasciola spp. that affects multiple hosts worldwide. Genetic characterization studies have revealed considerable diversity within F. hepatica populat...

Abstract This study aimed to investigate the genetic diversity of Hepatozoon spp. in rodents from Valdivia, Chile. A total of 74 rodents (synanthropic n=38; wild n=36) were trapped in Valdivia. We performed conventional ...

Orf virus causes infections in sheep and goats with lesions especially around muzzle and mouth. The disease is widespread, and most sheep-rearing countries are not free of infection. Disease is caused by ORF virus (ORFV)...

BackgroundCoxiella burnetii is the causative agent of Q fever, a zoonotic infection that poses serious threats to both animal and human health, particularly in the Global South. It infects livestock such as cattle, sheep...

Over the past three decades, a new picture of our own ancestral past has emerged through the elucidation of the complex genetic relationships between Neanderthals, Denisovans, and modern humans by the direct analysis of ...

Abstract Background Phylodynamics, the study of the interaction between epidemiological and pathogen evolutionary processes within and among populations, was originally defined in the context of rapidly evolving viruses ...

Megamelus is a genus of Delphacidae widely distributed and mostly associated with plants in freshwater environments. Despite various taxonomic revisions and thorough research, the delimitation of the genus, its diversity...
