The cavity-nesting honeybee inhabits only the highlands of Mount Kinabalu of Sabah, Borneo Island. The mitochondrial genome is a circular molecule of approximately 1.6 kb that includes 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one AT-rich control region. The average AT content was 84.5%. The start codons ATC, ATG, and ATT were found in one, three, and nine genes, respectively, whereas the stop codon TAA was observed in all genes. The phylogenetic relationship, inferred using 13 PCGs, was consistent with that reported in previous studies that predicted a sister taxon relationship between and .

Article Synopsis
- The Mesilau Stream Toad (Ansonia guibei) is a rare species found only in a specific area of Mount Kinabalu, Borneo, and is threatened by habitat loss due to a major earthquake in 2015, which severely impacted its population.
- After a survey in 2017 failed to find any specimens, it was declared Critically Endangered by the IUCN.
- However, recent surveys in late 2023 discovered a single subadult toad and tadpoles in local waterways, indicating that the species is still breeding and has some resilience, leading to ongoing efforts for its conservation.
Microstructure and crystallographic texture data in modern giant clam shells ( and ).
Data Brief

Cardiff University, School of Earth and Environmental Sciences, United Kingdom.
This article provides novel data on the microstructure and crystallographic texture of modern giant clam shells ( and ) from the Coral Triangle region of northeast Borneo. Giant clams have two aragonitic shell layers-the inner and outer shell layer. This dataset focuses on the inner shell layer as this is well preserved and not affected by diagenetic alteration.

The airfoil blade is the primary component of a wind turbine, and its aerodynamic properties play a crucial role in determining the energy conversion efficiency of these blades. Many researchers have proposed different airfoil modifications intending to enhance the aerodynamic characteristics and limit the unsteady interaction with the atmospheric boundary layer. This study evaluates the benefits of mounting wedge tails (WTs) on the trailing edge of an airfoil.

Background And Aims: While isotopic enrichment of nitrogen (15N) and carbon (13C) is often used to determine whether carnivorous plant species capture and assimilate nutrients from supplemental sources such as invertebrate prey or mammal excreta (heterotrophic nutrition), little is known about how successful the different strategies deployed by carnivorous plants are at obtaining supplemental nutrition. The collection of mammalian faeces by Nepenthes (tropical pitcher plants) is the result of a highly specialized biological mutualism that results in heterotrophic nitrogen gain; however, it remains unknown how effective this strategy is in comparison to Nepenthes species not known to collect mammalian faeces.
Methods: We examined how isotopic enrichment varied in the diverse genus Nepenthes, among species producing pitchers for invertebrate capture and species exhibiting mutualisms for the collection of mammal excreta.
