1. Cryptic speciation along a bathymetric gradient

Author:
Glazier, Amanda E.; Etter, Ron J.
Source:
Biological journal of the Linnean Society 2014 v.113 no.4 pp. 897-913

Subject:
calmodulin; cytochrome-c oxidase; ecosystems; fauna; gene flow; genetic variation; haplotypes; introns; loci; new species; phylogeny
Abstract:
... The deep ocean supports a highly diverse and mostly endemic fauna, yet little is known about how or where new species form in this remote ecosystem. How speciation occurs is especially intriguing in the deep sea because few obvious barriers exist that would disrupt gene flow. Geographic and bathymetric patterns of genetic variation can provide key insights into how and where new species form. We q ...

2. Genetic population structure in prickly sculpin (Cottus asper) reflects isolation‐by‐environment between two life‐history ecotypes

Author:
Dennenmoser, Stefan; Rogers, Sean M.; Vamosi, Steven M.

Biological journal of the Linnean Society 2014 v.113 no.4 pp. 943-957
ISSN:

Subject:
Cottus asper; developmental stages; ecotypes; estuaries; freshwater; gene flow; genetic variation; habitats; life history; microsatellite repeats; population structure; rivers; British Columbia
Abstract:
... Life‐history transitions have evolved repeatedly in numerous taxa, although the ecological and evolutionary conditions favouring such transitions in the presence of gene flow remain poorly understood. The present study aimed to disentangle the effects of isolation‐by‐distance and isolation‐by‐environment on genetic differentiation between two sympatric life‐history ecotypes. Using 14 microsatellit ...

3. Pattern‐oriented modelling of population genetic structure

Author:
Diniz‐Filho, José Alexandre Felizola; Soares, Thannya Nascimento; Telles, Mariana Pires De Campos
Source:
Biological journal of the Linnean Society 2014 v.113 no.4 pp. 1152-1161
ISSN:

Subject:
autocorrelation; cerrado; gene flow; gene frequency; genetic variation; indigenous species; models; population size; population structure; trees; variance
Abstract:
... Although several statistical approaches can be used to describe patterns of genetic variation and infer stochastic differentiation, selective responses, or interruptions of gene flow due to physical or environmental barriers, it is worthwhile to note that similar processes, controlled by several parameters in theoretical models, frequently give rise to similar patterns. Here, we develop a Pattern‐ ...

4. Phylogeography of the humbug damselfish, Dascyllus aruanus (Linnaeus, 1758): evidence of Indo‐Pacific vicariance and genetic differentiation of peripheral populations

Subject:
Dascyllus; corals; cytochrome b; fish; genetic variation; habitat destruction; habitats; microsatellite repeats; phylogeography; sea level; Pacific Ocean; Red Sea; Society Islands
Abstract:
... The phylogeographical structure of coral‐associated reef fishes may have been severely affected, more than species from deeper habitats, by habitat loss during periods of low sea level. The humbug damselfish, Dascyllus aruanus, is widely distributed across the Indo‐West Pacific, and exclusively inhabits branching corals. We used mitochondrial cytochrome b sequence and seven microsatellite loci on ...

5. Strong matrilineal structure in common pipistrelle bats (Pipistrellus pipistrellus) is associated with variability in echolocation calls

Author:

Biological journal of the Linnean Society 2014 v.113 no.4 pp. 1115-1125

Subject:
Pipistrellus pipistrellus; females; genetic variation; heritability; intraspecific variation; learning; males; microsatellite repeats; mitochondrial DNA; ontogeny; philopatry; progeny; social structure; Central European region
Abstract:
... The ontogeny and heritability of echolocation, an important sense in echolocating bats, is still not completely understood. Intraspecific variation in echolocation calls can be high, although the importance of possible explanatory variables (e.g. age, sex, social groups) remains largely unknown. Echolocation pulse features may vary among maternity roosts and this can theoretically be caused either ...
