Toward an Ethnoarchaeomalacology of Achatina in East Africa

open access: yesEthnobiology Letters, 2017
Land snail shell is a material commonly identified in the Late Holocene archaeological record of eastern Africa. Typically, archaeologists designate land snail shell as a natural occurrence or as debris produced from human subsistence.

Evolution of microgastropods (Ellobioidea, Carychiidae): integrating taxonomic, phylogenetic and evolutionary hypotheses [PDF]

open access: yes, 2013
BACKGROUND: Current biodiversity patterns are considered largely the result of past climatic and tectonic changes. In an integrative approach, we combine taxonomic and phylogenetic hypotheses to analyze temporal and geographic diversification of epigean (

Life cycle assessment of biodiesel synthesis from waste cooking oil using bifunctional heterogeneous catalyst

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...

Species diversity of land snails in limestone hills in Loei and Nong Bua Lamphu Provinces [PDF]

open access: yesWarasan Witthayasat Lae Theknoloyi Mahawitthayalai Mahasarakham, 2020
Limestone hills are a popular places that researchers use to study species diversity of land snails. Limestone hills provide not only a source of calcium carbonate that is important for shell formation, but also provides various types of microhabitat ...

Supergenes in polymorphic land snails [PDF]

open access: yesHeredity, 1976
The colour and banding of the shell of Partula suturalis are controlled by a single locus (M) with a series of at least six alleles. MX, giving apex as a homozygote, is dominant to MF1, giving frenata, which is dominant to the other alleles. MF2 is similar to MF1 except in its relation with MA.

Bridging the Gap: Student Voices on Recruitment and Retention in Ecology

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Students entering ecology and environmental science face a variety of challenges, including limited awareness of career paths, lack of mentorship, and difficulties connecting with peers and faculty. These challenges are often amplified for students from marginalized backgrounds, who may also encounter microaggressions, underrepresentation, and

Antibacterial and Antifungal Activities of Proteins Extracted from Seven Different Snails

open access: yesApplied Sciences, 2018
Snails have been used both as a food and as a treatment for a variety of medicinal conditions. In this study, seven different snail proteins were evaluated for their antimicrobial activity. Fresh water and land snails of seven different live species were

Genomic signatures of host-associated divergence and adaptation in a coral-eating snail, Coralliophila violacea (Kiener, 1836). [PDF]

open access: yes, 2020
The fluid nature of the ocean, combined with planktonic dispersal of marine larvae, lowers physical barriers to gene flow. However, divergence can still occur despite gene flow if strong selection acts on populations occupying different ecological niches.
