The role of aquaria in the advancement of elasmobranch reproductive biology
Frontiers in Marine Science, 2022 Public aquaria showcase aquatic life while raising awareness and educating the public on biodiversity and the need for conservation. Recently, aquaria have followed in the footsteps of zoos by taking more directed approaches in species conservation as ...

Insect Science, EarlyView.Overview of the mindset and long‐term goals with the approach suggested in this study. We provide a first proof of concept that male‐killing endosymbionts can be used to establish female biased populations with higher production efficiency than populations with a 50/50 sex ratio. This biological tool can have marked positive impact on future commercial

Phylogenetically Distant BABY BOOM Genes From Setaria italica Induce Parthenogenesis in Rice
Frontiers in Plant Science, 2022 The combination of apomixis and hybrid production is hailed as the holy grail of agriculture for the ability of apomixis to fix heterosis of F1 hybrids in succeeding generations, thereby eliminating the need for repeated crosses to produce F1 hybrids ...

Methods in Ecology and Evolution, EarlyView.Abstract Structured population models are parameterized to accurately project expected population sizes, stage/state distributions and population growth rates, but they also predict the variation in outcomes among individuals, such as the variance and skewness of lifetime reproductive output (LRO) and lifespan, the probability of never reproducing, and

A genetic basis for facultative parthenogenesis in Drosophila.
, 2023 Facultative parthenogenesis enables sexually reproducing organisms to switch between sexual and asexual parthenogenetic reproduction. To gain insights into this phenomenon, we sequenced the genomes of sexually reproducing and parthenogenetic strains of ...

Agricultural and Forest Entomology, EarlyView.Spirodiclofen resistance levels in B. yothersi varied geographically across the Brazilian citrus belt, with higher resistance in the central region. Sublethal effects included reduced oviposition, increased non‐viable eggs and disrupted female reproduction.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)
Agricultural and Forest Entomology, EarlyView.We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Agricultural and Forest Entomology, EarlyView.The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Parthenogenesis in Hesiod’s Theogony
, 2014 This article examines female asexual reproduction, or parthenogenesis, in Hesiod’s Theogony and argues that it is a symptom of the unprecedented and unparalleled female presence Hesiod inserts into his cosmos.

Niche partitioning among sexual and unisexual Ambystoma salamanders
Ecosphere, 2016 Organisms that have ecologically similar sexual and asexual forms present an evolutionary puzzle, as theory predicts that eventually one form should eliminate the other.
