Software codesign between end users and developers to enhance utility for biodiversity conservation.

Creating software tools that address the needs of a wide range of decision-makers requires the inclusion of differing perspectives throughout the development process. Software tools for biodiversity conservation often fall short in this regard, partly because broad decision-maker needs may exceed the toolkits of single research groups or even institutions. We show that participatory, collaborative codesign enhances the utility of software tools for better decision-making in biodiversity conservation planning, as demonstrated by our experiences developing a set of integrated tools in Colombia.

Regulation of Safracin Biosynthesis and Transport in PMA22.

PMA22 produces safracins, a family of compounds with potent broad-spectrum anti-bacterial and anti-tumor activities. The safracins' biosynthetic gene cluster (BGC sac) consists of 11 ORFs organized in two divergent operons ( and ) that are controlled by and promoters. Contiguous to the BGC sac, we have located a gene that encodes a putative global regulator of the LysR family annotated as MexT that was originally described as a transcriptional activator of the MexEF-OprN multidrug efflux pump in .

A reference transcriptome of the aquatic oligochaete, , was reconstructed for the first time, and genes related to cell stress response (, , , and ), energy metabolism (), oxidative stress (, , and ), and the genes involved in the homeostasis of organisms (, , and ) were identified and characterised.

First report of fatal fungemia due in a patient with COVID-19 in Ecuador.

Filamentous fungal infections are an important cause of systemic infections in immunocompromised patients. genus members potentially cause disseminated infections, especially in patients with catheters, due to the ability to adhere to these devices. We describe a case of fatal fungemia due to in a patient with COVID-19 in Ecuador.

Xicotli Data: a project to retrieve plant-bee interactions from citizen science.

Background: Xicotli data is the short name given to the dataset generated within the project framework "Integration of Biodiversity Data for the Management and Conservation of Wild Bee-Plant Interactions in Mexico (2021-2023)", as xicotli is the generic word for a bee in Nahuatl. The team comprised eco-informaticians, ecologists and taxonomists of both native bees and flora. The generated dataset contains so far 4,532 curated records of the plants, which are potential hosts of species of three focal families of bees native to Mexico: Apidae, Halictidae and Megachilidae and morphological and ecological data of the plant-bee interactions.

Tailoring modifications in labrenzin synthesis: a-la-carte production of pathway intermediates.

Pederin-family polyketides today constitute a group of more than 30 molecules being produced as natural products by different microorganisms across multitude of ecological niches. They are mostly known for their extreme cytotoxic activity and the decades of long exploration as potential antitumor drugs. The difference in their potency and biological activity lies in the tailoring modifications of the core molecule.

Developing As and Cu Tissue Residue Thresholds to Attain the Good Ecological Status of Rivers in Mining Areas.

The study was performed on residue-effects datasets from polluted and unpolluted sites in the Nalón River basin (northern Spain). The effects were measured in terms of alteration of field macroinvertebrate communities, and measured as ecological status scores, and number of families and abundance of Ephemeroptera, Plecoptera and Trichoptera (EPT). Non-linear regression models of the field-measured tissue residues in 10 taxa related to the ecological status of the macroinvertebrate communities were used to derive effective tissue residues (ERs).

Ovary micromorphology and oogenesis in a rhyacodriline oligochaete (Clitellata: Naididae, Rhyacodrilinae).

The main goal of the article is to describe the ovary organization and oogenesis in Peristodrilus montanus, an aquatic oligochaete of the subfamily Rhyacodrilinae. The presented analysis will not only enrich the knowledge about how eggs are formed but, because of the suggested conservatism of ovary organization in clitellate annelids, can contribute to disentangling the complex phylogenetic relationships of the rhyacodrilines within Naididae. The paired, conically shaped ovaries are located in segment XI.

Bioaccumulation and chronic toxicity of arsenic and zinc in the aquatic oligochaetes Branchiura sowerbyi and Tubifex tubifex (Annelida, Clitellata).

Oligochaetes feed on bulk sediment and penetrate the sediment through the construction of burrows, making them especially vulnerable to sediment metal contamination. However, the few oligochaete species that have been tested to date are almost exclusively temperate test species. Although the warmwater adapted species Branchiura sowerbyi has been indicated as a promising candidate for tropical sediment toxicity testing, few (especially chronic) studies have been conducted so far to confirm this.

Proposal of integrative scores and biomonitor selection for metal bioaccumulation risk assessment in mine-impacted rivers.

Development of sound criteria for metal and metalloid bioaccumulation risk assessment in river basins affected by mining activities is a necessary tool to protect the aquatic communities. The aim of this study is to propose integrative scores for tissue residues that are suitable for surveillance programs and readily interpreted in terms of risk assessment in mining impacted rivers. Tissue residues of 7 trace metals and 2 metalloids were measured in ten macroinvertebrate taxa from the Nalón River basin (Spain), affected by Hg, Cu and Au mining activities.

Why do bugs perish? Range size and local vulnerability traits as surrogates of Odonata extinction risk.

Despite claims of an insect decline worldwide, our understanding of extinction risk in insects is incomplete. Using bionomic data of all odonate (603 dragonflies and damselflies) North American species, we assessed (i) regional extinction risk and whether this is related to local extirpation; (ii) whether these two patterns are similar altitudinally and latitudinally; and (iii) the areas of conservation concern. We used geographic range size as a predictor of regional extinction risk and body size, thermal limits and habitat association as predictors of local extirpation.

Changes in invertebrate community composition allow for consistent interpretation of biodiversity loss in ecological status assessment.

Biological communities change in response to human alteration. The response of individual taxa and the community can be used to establish preventive criteria to halt further biodiversity deterioration. Here we explore how consistent are the boundaries between Good and Moderate ecological status derived from classification systems used in North-NW Spain: NORThern Spain Indicators system (NORTI), River type specific multimetric (METI) and Iberian Bio-monitoring Working Party (IBMWP), by using common interpretation of normative definitions of Water Framework Directive.
