Introduction Cold-adapted bumblebees are vulnerable to climate change (CC). South American Bombus dahlbomii, the southernmost bumblebee worldwide, has strongly declined since the 1990s and may be particularly susceptible to current and future CC. Aims/methods We asked (1) whether current CC had a role in the observed decline of this species and (2...
Article
Adequate pollination is fundamental to optimize reproduction and yield of most flowering plants, including many staple food crops. Plants depending on insect pollination rely heavily on many wild species of solitary and social bees, and declines or absence of bees often hampers crop productivity, prompting supplementation of pollination services wi...
Article
Invasive alien species generate adverse ecological, economic and social impacts in the invaded area. This is particularly alarming as the establishment of alien species shows no sign of saturation worldwide. Among invasive alien species, social wasps of the Vespidae family are well known to negatively impact the biodiversity and economy in the inva...

Diphyllobothriosis was first recorded in humans in Argentina in 1892 and in introduced salmonids in 1952. The aim of this work is to assess factors influencing the values of prevalence and abundance of plerocercoids in fishes that could increase the risk of transmission of Dibothriocephalus spp. in Andean Patagonian lakes. We analysed two key issue...

Diphyllobothriosis is a reemerging zoonotic disease because of global trade and increased popularity of eating raw fish. We present molecular evidence of host switching of a human-infecting broad fish tapeworm, Dibothriocephalus latus, and use of salmonids as intermediate or paratenic hosts and thus a source of human infection in South America.

Eusociality, a form of animal social organization involving sterile and reproductive castes, is a rare, but highly ecologically successful form of life. There are striking examples of eusocial species with populations that are ecologically dominant in their native ranges, as well as remarkably successful globally as invasive species; prominent exam...

Although competition and predation are mechanisms more studied in biological invasions, ecologists and conservation managers have become aware of the threat imposed by the co-introduction of parasites. Parasites can be co-introduced into new areas with a non-native host, and become co-invaders when they spill over to native hosts. The copepod Lerna...

Diphyllobothriidea are the principal agents of Diphyllobothriosis, a widespread food-borne cestodosis. Accurate identification of the species in samples is therefore crucial for diagnosis and epidemiology in wild and domestic animals, and also humans. We aim to identify at specific level the causative agent, and provide an observational, descriptiv...

Article
In view of global climate change, it is important to understand the responses of tree species to climate changes in the past. Combinations of phylogeographic analysis of genetic evidence, coupled with species distribution models (SDMs), are improving our understanding on this subject. We combined SDMs and microsatellite data from populations of the...

La difilobotriosis es una zoonosis causada por un cestode del género Diphyllobothrium y es típica de climas templado-fríos. En su ciclo de vida, los huevos son liberados al ambiente acuático junto con las heces de los hospedadores definitivos que son aves y mamíferos ictiófagos o el hombre. Del huevo eclosiona el coracidio, que nada en el ambiente...

The worldwide spread of diseases is considered a major threat to biodiversity and a possible driver of the decline of pollinator populations, particularly when novel species or strains of parasites emerge. Previous studies have suggested that populations of introduced European honeybee (Apis mellifera) and bumblebee species (Bombus terrestris and B...
Article
Despite rising global concerns over the potential impacts of non-native bumble bee (Bombus spp) introductions on native species, large-scale and long-term assessments of the consequences of such introductions are lacking. Bombus ruderatus and Bombus terrestris were sequentially introduced into Chile and later entered Argentina's Patagonian region....

The worldwide trade in bumblebees can lead to the spread of diseases, which in turn has been claimed as a factor in bumblebee decline. Populations of the introduced Bombus terrestris, which invaded NW Patagonia, Argentina, in 2006, harbor the highly pathogenic protozoan Apicystis bombi. We asked whether A. bombi had been co-introduced with B. terre...

The evolutionary history of populations and species play a major role in determing the levels and distribution patterns of genetic variants. Particularly range contractions during Pleistoce glaciations (c. 18,000 yr. Bp) followed by recolonization after glacial retreat are thought to affect genetic patterns. Hotspots of genetic diversity and among-...
