Abstract Cestodes of the genusArostrilepisMas-Coma and Tenora 1997 have a Holarctic distribution with 16 species occurring among 28 species of mostly arvicoline hosts. The type species of the genus isArostrilepis horrida(von Linstow, 1901), described initially asTaenia horridavon Linstow, 1901, from murine rodents in Lower Saxony (Niedersachsen), Germany. Here we report the first helminth parasite from the mole-vole,Ellobius tancrei, in Mongolia which is the first subterranean rodent known to be infected withArostrilepisin the Palearctic. In addition, we describe a new species:Arostrilepis batsaikhanin. sp. which most closely resemblesA. microtisGulyaev and Chechulin 1997, differing from this species with a genetic distance of about 4% (using cytochrome-b) and by having distinctly large cirrus spines, testes that are larger and fill the whole segment measured anterior–posterior and larger eggs.

Helminth parasites of Galápagos mammals: a new cestode of the genus Raillietina from the endemic rice rat Nesoryzomys swarthi and a summary of parasites from both endemic and invasive rodents
Abstract In this first report of endoparasites from endemic land-mammals of the Galápagos Islands, we describe a new species of cestode of the genusRaillietina(Cyclophyllidea: Davaineidae) from a species ofNesoryzomysand summarize the extent of helminth parasitism in both oryzomyine endemics and introduced species ofRattus. Up to the current time, no helminth parasites have been reported from rodents of the Galápagos, and little work has yet been done describing and synthesizing Galápagos parasite diversity. In historical times, several species of autochthonous rodents have occupied the islands including:Nesoryzomys narboroughiHeller 1904,N. fernandinaeHutterer and Hirsch 1979,N. swarthiOrr, 1938, andAegialomys galapagoensis(Waterhouse, 1839). Colonization of the islands by humans brought 3 known species of synanthropic rodents:Rattus rattus, R. norvegicus, andMus musculuswhich are suspected to have caused the extinction of at least 3 other oryzomyines in historical times.

ABSTRACT Hantaviruses are globally distributed zoonotic pathogens capable of causing fatal disease in humans. Addressing the risk of hantavirus spillover from animal reservoirs to humans requires identifying the local reservoirs (usually rodents and other small mammals) and the predictors of infection, such as habitat characteristics and human exposure. We screened a collection of 1663 terrestrial small mammals and 227 bats for hantavirus RNA, comprised of native and non‐native species from northeastern Madagascar, trapped over 5 successive years. We specifically investigated the influence of diverse habitat types: villages, agricultural fields, regrowth areas, secondary and semi‐intact forests on infection with hantaviruses. We detected Hantavirus RNA closely related to the previously described Anjozorobe virus in 9.5% ofRattus rattussampled, with an absence of detection in other species. Land‐use had a complex impact on hantavirus infections: intensive land‐use positively correlated with the abundance ofR. rattusand the averageR. rattusbody size varied between habitats. Larger individuals had a higher probability of infection, regardless of sex. Thus, villages and pristine forests which host the smallest, and hence, least infected rats, represent the lowest risk for hantavirus exposure to people while flooded rice fields which were home to the largest rats, and subsequently most infected rats, represent the greatest exposure risk. These findings provide new insights into the relationship between rat ecology and the gradients of hantavirus exposure risk for farmers in northeastern Madagascar as they work in different land‐use types.more » « less

Abstract DNA sequences were obtained from 32 blade-formingUlvaspecimens collected in 2018 and 2019 from four islands in the Galápagos Archipelago: Fernandina, Floreana, Isabela and San Cristóbal. The loci sequenced were nuclear encoded ITS and plastid encodedrbcL andtufA, all recognized as barcode markers for green algae. Four species were found,Ulva adhaerens,U. lactuca,U. ohnoiandU. tanneri, all of which have had their type specimens sequenced, ensuring the correct application of these names. Only one of these,U. lactuca, was reported historically from the archipelago.Ulva adhaerenswas the species most commonly collected and widely distributed, occurring on all four islands. Previously known only from Japan and Korea, this is the first report ofU. adhaerensfrom the southeast Pacific Ocean.Ulva ohnoiwas collected on three islands, Isabela, Floreana, and San Cristóbal, andU. lactucaonly on the last two.Ulva tanneriis a diminutive, 1–2 cm tall, high intertidal species that is easily overlooked, but likely far more common than the one specimen that was collected. This study of blade-formingUlvaspecies confirms that a concerted effort, using DNA sequencing, is needed to document the seaweed flora of the Galápagos Archipelago.more » « less

Abstract AimTo determine the historical dynamics of colonization and whether the relative timing of colonization predicts diversification rate in the species‐rich, murine rodent communities of Indo‐Australia. LocationIndo‐Australian Archipelago including the Sunda shelf of continental Asia, Sahul shelf of continental Australia, the Philippines and Wallacea of Indonesia. TaxonOrder Rodentia, Family Muridae. MethodsWe used a fossil‐calibrated molecular phylogeny and Bayesian biogeographical modelling to infer the frequency and temporal sequence of biogeographical transitions among Sunda, Sahul, the Philippines and Wallacea. We estimated diversification rates for each colonizing lineage using a method‐of‐moments estimator of net diversification and Bayesian mixture model estimates of diversification rate shifts. ResultsWe identified 17 biogeographical transitions, including nine originating from Sunda, seven originating from Sulawesi and broader Wallacea and one originating from Sahul. Wallacea was colonized eight times, the Phillipines five times, Sunda twice and Sahul twice. Net diversification rates ranged from 0.2 to 2.12 species/lineage/My with higher rates in secondary and later colonizers than primary colonizers. The highest rates were in the genusRattusand their closest relatives, irrespective of colonization history. Main ConclusionsOur inferences from murines demonstrate once again the substantial role of islands as sources of species diversity in terrestrial vertebrates of the IAA with most speciation events occurring on islands. Sulawesi and broader Wallacea have been a major source of colonists for both island and continental systems. Crossings of Wallace's Line were more common than subsequent transitions across Lydekker's Line to the east. While speciation following colonization of oceanic archipelagos and large islands is consistent with adaptive radiation theory and ideas regarding ecological opportunity, we did not observe a strong signal of incumbency effects. Rather, subsequent colonists of landmasses radiated unhindered by previous radiations.more » « less

Abstract Newly arrived species on young or remote islands are likely to encounter less predation and competition than source populations on continental landmasses. The associated ecological release might facilitate divergence and speciation as colonizing lineages fill previously unoccupied niche space. Characterizing the sequence and timing of colonization on islands represents the first step in determining the relative contributions of geographical isolation and ecological factors in lineage diversification. Herein, we use genome-scale data to estimate timing of colonization in Naesiotus snails to the Galápagos islands from mainland South America. We test inter-island patterns of colonization and within-island radiations to understand their contribution to community assembly. Partly contradicting previously published topologies, phylogenetic reconstructions suggest that most Naesiotus species form island-specific clades, with within-island speciation dominating cladogenesis. Galápagos Naesiotus also adhere to the island progression rule, with colonization proceeding from old to young islands and within-island diversification occurring earlier on older islands. Our work provides a framework for evaluating the contribution of colonization and in situ speciation to the diversity of other Galápagos lineages.more » « less
