Speciation of pelagic zooplankton: Invisible boundaries can drive isolation of oceanic ctenophores

open access: yesFrontiers in Genetics, 2022
The study of evolution and speciation in non-model systems provides us with an opportunity to expand our understanding of biodiversity in nature. Connectivity studies generally focus on species with obvious boundaries to gene flow, but in open-ocean ...

Genomic data do not support comb jellies as the sister group to all other animals [PDF]

open access: bronzeProceedings of the National Academy of Sciences, 2015
SignificanceClarifying the phylogeny of animals is fundamental to understanding their evolution. Traditionally, sponges have been considered the sister group of all other extant animals, but recent genomic studies have suggested comb jellies occupy that position instead.

First records of two lobate comb-jellies (Ctenophora) from the Pakistani coast [PDF]

open access: goldCheck List, 2015
The knowledge on the comb-jellies faunistics along the southern Asian coast is very scarce. For some countries such as Pakistan there are no previous formal records of ctenophores. This study is a first survey to the group diversity along Pakistani coast, resulting in the first records of two lobate species, Bolinopsis infundibulum and Ocyropsis ...

Free-swimming fauna associated with influxes of pelagic sargassum: Implications for management and harvesting

open access: yesFrontiers in Marine Science, 2023
Mass accumulations of pelagic sargassum (Sargassum natans and S. fluitans) in the Tropical Atlantic, across the Caribbean and off the coast of West Africa, are causing extensive ecological and socioeconomic harm.

Honey Bee Exposure to the Fungicide Propiconazole in Lowbush Blueberry Fields

open access: yesAgronomy, 2022
The fungicide propiconazole is a commonly used fungicide in small fruit and tree fruit production in the U.S.A. In Maine wild blueberry production, it is used almost exclusively for mummy berry disease control.

Modelling survival and connectivity of Mnemiopsis leidyi in the south-western North Sea and Scheldt estuaries [PDF]

open access: yes, 2015
Three different models were applied to study the reproduction, survival and dispersal of Mnemiopsis leidyi in the Scheldt estuaries and the southern North Sea: a high-resolution particle tracking model with passive particles, a low-resolution particle ...

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.
