Tourism and urban development as drivers for invertebrate diversity loss on tropical islands
<p>Oceanic islands harbour a disproportionately high number of endemic and threatened species. Rapidly growing human populations and tourism are posing an increasing threat to island biota, yet the ecological consequences of these human land uses on small oceanic island systems have not been quantified. Here, we investigated and compared the impact of tourism and urban island development on ground-associated invertebrate biodiversity and habitat composition on oceanic islands. To disentangle tourism and urban land uses, we investigated Indo-Pacific atoll islands, which either exhibit only tourism or urban development, or remain uninhabited. Within the investigated system, we show that species richness, abundance, and Shannon diversity of the ground-associated invertebrate community are significantly decreased on islands used for tourism and on islands with urban development, relative to uninhabited islands. Remote-sensing-based spatial data suggests that habitat fragmentation and a reduction in vegetation density are having significant effects on biodiversity on urban islands, whereas land use/ cover changes could not be linked to the documented biodiversity loss on tourist islands. This offers first direct evidence for a major terrestrial invertebrate loss on remote oceanic islands due to different human land uses with yet unforeseeable long-term consequences for the stability and resilience of oceanic island ecosystems.</p>
Supporting data for: Gene-rich UV sex chromosomes harbor conserved regulators of sexual development (Carey et al., 2021)
<p>Non-recombining sex chromosomes, like the mammalian Y, often lose genes and accumulate transposable elements, a process termed degeneration. The correlation between suppressed recombination and degeneration is clear in animal XY systems, but the absence of recombination is confounded with other asymmetries between the X and Y. In contrast, UV sex chromosomes, like those found in bryophytes, experience symmetrical population genetic conditions. Here we generate and use nearly gapless female and male chromosome-scale reference genomes of the moss <i>Ceratodon purpureus </i>to test for degeneration in the bryophyte UV sex chromosome system. We show the moss sex chromosomes evolved over 300 million years ago and expanded via two chromosomal fusions. Although the sex chromosomes show signs of weaker purifying selection than autosomes, we find suppressed recombination alone is insufficient to drive gene loss on sex-specific chromosomes. Instead, the U and V sex chromosomes harbor thousands of broadly-expressed genes, including numerous key regulators of sexual development across land plants.</p>
Data from: Female developmental environment delays development of male honeybee (Apis mellifera)
<p><b><span>Background</span></b></p> <p>Nutrition and cell size play an important role in the determination of caste differentiation in queen and worker of honeybees (<i><span>Apis mellifera</span></i>), whereas the haploid genome dominates the differentiation of drones. However, the effects of female developmental environment on the development of males remain unclear. In this study, young drone larvae were transferred into worker cells (WCs) or remained in drone cells (DCs) to rear drones. The drone larvae were also grafted into queen cells (QCs) for 48 hrs and then transplanted into drone cells until emerging. Morphological indexes and reproductive organs of these three types of newly emerged drones were measured. Newly emerged drones and 3-day drone larvae from WCs, DCs and QCs were sequenced by RNA sequencing (RNA-Seq).</p> <p><b><span>Result</span></b><b><span>s</span></b></p> <p>The amount of food remaining in cells of the QC and WC groups was significantly different to that in the DC group at the early larval stage. Morphological results showed that newly emerged DC drones had bigger body sizes and more well-developed reproductive tissues than WC and QC drones, whereas the reproductive tissues of QC drones were relatively larger than those of WC drones. Additionally, gene expression results showed a clear difference among three groups. At the larval stage, there were 889, 1761 and 1927 significantly differentially expressed genes (DEGs) in WC/DC, QC/DC and WC/QC comparisons, respectively. The number of DEGs decreased in adult drones of these three comparisons [678 (WC/DC), 338 (QC/DC) and 518 (WC/QC)]. A high number of DEGs were involved in sex differentiation, growth, olfaction, vision, mammalian target of rapamycin (mTOR), Wnt signaling pathways, and other processes. </p> <p><b><span>Conclusion</span></b></p> <p>This study demonstrated that the developmental environment of honeybee females can delay male development, which serves as a model for understanding the regulation of sex differentiation and male development in social insects by environmental factors.</p>
