Phylogeography of a good Caribbean disperser: .

ZooKeys

Agnarsson I, LeQuier SM, Kuntner M, Cheng RC, Coddington JA, Binford G.
PMID: 27833425
Zookeys. 2016 Oct 19;(625):25-44. doi: 10.3897/zookeys.625.8729. eCollection 2016.

The Caribbean islands harbor rich biodiversity with high levels of single island endemism. Stretches of ocean between islands represent significant barriers to gene-flow. Yet some native species are widespread, indicating dispersal across oceans, even in wingless organisms like spiders.

Spintharus flavidus in the Caribbean-a 30 million year biogeographical history and radiation of a 'widespread species'.

The Caribbean island biota is characterized by high levels of endemism, the result of an interplay between colonization opportunities on islands and effective oceanic barriers among them. A relatively small percentage of the biota is represented by 'widespread species,'...

[DNA flow cytometry is a useful prognostic guide in the treatment of breast cancer.].

Laeknabladid

Gudlaugsdottir S, Sigurdsson H, Agnarsson BA, Jonasson JG, Kristjansdottir S, Baldursson G, Bjornsson S, Sveinsson T, Egilsson V.
PMID: 20065406
Laeknabladid. 1996 Feb;82(2):138-47.

It is widely agreed that the presence or absence of axillary lymph-node involvement (N) is the most reliable predictor of relapse or survival in breast cancer, together with tumor size (T) and the presence or absence of distant metastasis...

A time-calibrated species-level phylogeny of bats (Chiroptera, Mammalia).

PLoS currents

Agnarsson I, Zambrana-Torrelio CM, Flores-Saldana NP, May-Collado LJ.
PMID: 21327164
PLoS Curr. 2011 Feb 04;3:RRN1212. doi: 10.1371/currents.RRN1212.

Despite their obvious utility, detailed species-level phylogenies are lacking for many groups, including several major mammalian lineages such as bats. Here we provide a cytochrome b genealogy of over 50% of bat species (648 terminal taxa). Based on prior...

Island biogeography and ecological modeling of the amblypygid .

AIM: The biogeography of terrestrial organisms across the Florida Keys archipelago is poorly understood. We used population genetics and spatioecological modeling of the Amblypygi LOCATION: The Florida Keys archipelago and mainland Florida.METHODS: We sequenced a 1,238 bp fragment of...

Spiders did not repeatedly gain, but repeatedly lost, foraging webs.

PeerJ

Coddington JA, Agnarsson I, Hamilton CA, Bond JE.
PMID: 30976470
PeerJ. 2019 Apr 04;7:e6703. doi: 10.7717/peerj.6703. eCollection 2019.

Much genomic-scale, especially transcriptomic, data on spider phylogeny has accumulated in the last few years. These data have recently been used to investigate the diverse architectures and the origin of spider webs, concluding that the ancestral spider spun no...

[Age and sex specific prevalence of lens opacifications in Iceland.].

Laeknabladid

Arnarsson A, Jonasson F, Jonsson V, Sasaki H, Stefansson E, Bjarnadottir G, Hardarson T, Bjarnadottir A, Sasaki K.
PMID: 19439785
Laeknabladid. 1999 Oct;85(10):778-86.

OBJECTIVES: Cataract is one of the most common causes for blindness in the world, though not in Iceland due to availability of cataract surgery. The aim of this study was to establish the age and sex specific prevalence of...
