title: The case for measuring adults’ numeracy practices

authors: Coben, Diana

subjects: Adult's Numeracy Practices

abstract: In this article, we make the case for the development of a numeracy practices measure in the light of a review of relevant research and extant measures. We argue that a numeracy practices measure would acknowledge and validate adult learners’ practice gains and inform teaching geared to their circumstances, needs and interests.

title: Stable isotope and molecular analyses indicate that hybridization with non-native domesticated common carp influence habitat use of native carp

authors: Matsuzaki, Shin-ichiro S.

subjects: non-native species

abstract: Hybridization between native and non-native species has consequences for survival and growth rates of hybrid offspring, but the influences on their functional roles such as habitat use are little studied and poorly understood. The Japanese native common carp Cyprinus carpio coexist and hybridize with non-native domesticated carp in natural Japanese lakes. We have combined stable isotope and molecular information to examine whether habitat use of carp varies depending on the degree of hybridization between native and non-native carp. We sampled 69 carp from Lake Kasumigaura where hybrid swarms between native and non-native carp are advancing, evaluated the degree of hybridization for each individual by genotyping five single nucleotide polymorphism (SNP) markers, and analyzed their carbon and nitrogen stable isotopes. Although we did not find any genetically pure native carp in the lake, the results showed that carp δ13C increased with increasing frequency of non-native alleles but that δ15N did not change. This indicates that non-native carp use the littoral zone more frequently than native carp. This difference in habitat use was supported by a multisource mixing model, showing that the contribution of limnetic primary consumers to the diets of non-native carp was lower than that of individuals with the highest frequency of native alleles. By combining two very different methods, our results thus suggest that multiple-generation hybridization can influence habitat and resource use. Habitat partitioning should be considered when evaluating the genetic impacts of invasive species and races on native species and ecosystem processes.

title: Balancing openness with Indigenous data sovereignty: An opportunity to leave no one behind in the journey to sequence all of life

authors: Cartney, Ann M. Mc

abstract: The field of genomics has benefited greatly from its "openness" approach to data sharing. However, with the increasing volume of sequence information being created and stored and the growing number of international genomics efforts, the equity of openness is under question. The United Nations Convention of Biodiversity aims to develop and adopt a standard policy on access and benefit-sharing for sequence information across signatory parties. This standardization will have profound implications on genomics research, requiring a new definition of open data sharing. The redefinition of openness is not unwarranted, as its limitations have unintentionally introduced barriers of engagement to some, including Indigenous Peoples. This commentary provides an insight into the key challenges of openness faced by the researchers who aspire to protect and conserve global biodiversity, including Indigenous flora and fauna, and presents immediate, practical solutions that, if implemented, will equip the genomics community with both the diversity and inclusivity required to respectfully protect global biodiversity.
