Evolution and loss of long-fringed petals [PDF]

open access: yes, 2012
Background: The Cucurbitaceae genus Trichosanthes comprises 90–100 species that occur from India to Japan and southeast to Australia and Fiji. Most species have large white or pale yellow petals with conspicuously fringed margins, the fringes sometimes ...

Phylogenomics Reveals the Evolutionary History of Phytolacca (Phytolaccaceae)

open access: yesFrontiers in Plant Science, 2022
Phytolacca is the largest genus of Phytolaccaceae. Owing to interspecific hybridization, infraspecific variation, and apparent weak genetic control of many qualitative characters, which have obscured boundaries between species, the classification and ...

Beyond similarity: A network approach for identifying and delimiting biogeographical regions [PDF]

open access: yes, 2014
Biogeographical regions (geographically distinct assemblages of species and communities) constitute a cornerstone for ecology, biogeography, evolution and conservation biology.

Orchids of the State Park of Serra do Tabuleiro, Southern Brazil

open access: yesAnales del Jardín Botánico de Madrid, 2015
Orchidaceae show a high diversity of species in Brazil, especially in the Atlantic Forest Biome. Over the course of a 12-month study in the State Park of Serra do Tabuleiro in Southern Brazil, collections were made of orchids occurring in areas of ...

RADseq analyses reveal concordant Indian Ocean biogeographic and phylogeographic boundaries in the reef fish Dascyllus trimaculatus [PDF]

open access: yesRoyal Society Open Science, 2019
Population genetic analysis is an important tool for estimating the degree of evolutionary connectivity in marine organisms. Here, we investigate the population structure of the three-spot damselfish Dascyllus trimaculatus in the Red Sea, Arabian Sea and

Predicting plankton net community production in the Atlantic Ocean [PDF]

open access: yes, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

Dispersal and gene flow in free-living marine nematodes [PDF]

open access: yes, 2013
Dispersal and gene flow determine connectivity among populations, and can be studied through population genetics and phylogeography. We here review the results of such a framework for free-living marine nematodes.

Modelling the biogeographic boundary shift of Calanus finmarchicus reveals drivers of Arctic Atlantification by subarctic zooplankton [PDF]

open access: yesGlobal Change Biology, 2021
AbstractBiological communities in the Arctic are changing through the climate‐driven encroachment of subarctic species. This “Atlantification” extends to keystone Calanoid copepods, as the small‐bodied Calanus finmarchicus increases in abundance in areas where it overlaps with larger Arctic congeners.
