Kia ora friends! A big question- I’m looking for examples of my/ our work being used in teaching or other things. Especially work on whakataukī / mātauranga and ecology. Please DM or reply with examples including class, institution, & why - would so appreciate it! The evidence we rarely hear about 😆

🐦 Why are bird genomes so difficult to assemble? Birds have dozens of tiny, gene-rich microchromosomes that are frequently fragmented, misplaced, or missing from genome assemblies despite containing important genetic information. 📖 Read the publication: lnkd.in/gar-GrKZ #BirdGenomics #Biodiversity

The birds are arranged around the centered text, "MicroFinder Is Now Available," with "MicroFinder" in gold and "Is Now Available" in white. The image highlights the diversity of avian species and announces the release of the MicroFinder computational tool for improving bird genome assemblies.

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.

Huge News from the Western Amazon: it's the year 2025 and we are still describing entirely new, strikingly-distinctive large-bodied bird species! Behold Tinamus resonans sp. nov. the Slaty-masked Tinamou mapress.com/zt/article/v... #Ornithology @tetzoo.bsky.social 🪶
Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.
