Background: Recognition of the diversity of living beings, including the classification and naming of species, is a fundamental condition for biological literacy with the aim of developing critical awareness of human relationships with nature, and for which formal education plays an important role. The present study aimed to analyze the representation that urban/rural students have for wild vertebrates and their main sources of knowledge.

Methods: Data collection took place in three public schools, one urban and two rural, in the municipality of Campina Grande, Paraíba, Brazil. Questionnaires were given to 990 students (528 urban and 462 rural), distributed among all the grades that comprise middle school (Ensino Fundamental II, grades 6-9) and high school (Ensino Médio, grades 10-12) education.

Results: A total of 5877 citations were mentioned by the students, which corresponded to 224 distinct animals with 166 (72.0%) being wild vertebrates, 24 (25.7%) being domestic vertebrates, and 34 (2.3%) being invertebrates. Mammals and reptiles had the greatest observed richness of citations, while mammals (H' = 3.37), birds (H' = 2.84), and invertebrates (H' = 2.94) had the greatest diversity. Positive correlations were found between citations of wild vertebrates and family income (rt = 0.06; P < 0.05) and curricular development (rs = 0.08; P < 0.01); negative correlations were found between curricular development and citations of domestic animals (rs = - 0.22; rs = - 0.11 P < 0.01) and between age group and citations of invertebrates (r = - 0.14; rs = - 0.11 P < 0.01). As for the sources of knowledge regarding the animals indicated by the students, "media," "daily experiences," "tradition" (here understood as knowledge resulting from interactions with parents and experienced community members), and "formal education" stood out.

Conclusions: Comprehension of vertebrate diversity is a fundamental condition for the development of attitudes compatible with its conservation, which emphasizes the importance of biological literacy in achieving this purpose.

The angiopoietin (Ang)-Tie axis, critical for endothelial cell function and vascular development, is a promising therapeutic target for treating vascular disorders and inflammatory conditions like sepsis. This study aimed to enhance the binding affinity of recombinant Ang1 variants to the Tie2 and explore their therapeutic potential. Structural insights from the Ang1-Tie2 complex enabled the identification of key residues within the Ang1 receptor binding domain (RBD) critical for Tie2 interaction.

Engineering dimer mutants of human geranylgeranyl pyrophosphate synthase.

PLoS One

January 2025

Department of Biochemistry, Memorial University of Newfoundland, St. John's, Newfoundland and Labrador, Canada.

Geranylgeranyl pyrophosphate synthase (GGPPS), a key enzyme in protein prenylation, plays a critical role in cellular signal transduction and is a promising target for cancer therapy. However, the enzyme's native hexameric quaternary structure presents challenges for crystallographic studies. The primary objective of this study was to engineer dimeric forms of human GGPPS to facilitate high-resolution crystallographic analysis of its ligand binding interactions.

A framework for assessing reliability of observer annotations of aerial wildlife imagery, with insights for deep learning applications.

PLoS One

January 2025

Division of Biological Sciences, US Fish and Wildlife Southwest Regional Office, Albuquerque, New Mexico, United States of America.

There is growing interest in using deep learning models to automate wildlife detection in aerial imaging surveys to increase efficiency, but human-generated annotations remain necessary for model training. However, even skilled observers may diverge in interpreting aerial imagery of complex environments, which may result in downstream instability of models. In this study, we present a framework for assessing annotation reliability by calculating agreement metrics for individual observers against an aggregated set of annotations generated by clustering multiple observers' observations and selecting the mode classification.

Age- and Sex-Specific Regulation of Serine Racemase in the Retina of an Alzheimer's Disease Mouse.

Invest Ophthalmol Vis Sci

January 2025

State Key Laboratory of Ophthalmology, Optometry, and Visual Science, Eye Hospital, Wenzhou Medical University, Wenzhou, China.

Purpose: Changes associated with Alzheimer's disease (AD) may have measurable effects on the retina, which may facilitate early detection due to the eye's accessibility. Retinal pathology and the regulation of serine racemase (SR) were investigated in the retinas of APP(SW)/PS1(∆E9) mice.

Methods: SR in the retinas and the content of D-serine in the aqueous humor were analyzed.

The Riverine Barrier Hypothesis posits that species distributions are limited by large rivers acting as geographical barriers. Accordingly, large rivers have long been thought to be a major driver of the extensive speciation and high levels of biodiversity among platyrrhine primates in South and Central America. Direct observations of river crossings provide evidence that complements studies of genetic diversity that can together shed new light on this hypothesis.
