Article Synopsis
  • Climate change is causing shifts in animal habitats, particularly affecting the distribution of threatened marine species like whale sharks.
  • Projections indicate that by 2100, whale sharks could lose more than 50% of their core habitat in some areas, with significant geographic shifts that could place them in closer proximity to large ships.
  • The increase in whale shark interaction with shipping is expected to be dramatically higher under high emission scenarios compared to sustainable development, highlighting the urgency for better climate-threat predictions in conservation strategies for endangered marine life.

Article Synopsis
  • The study investigates population divergence in silvereye birds (Zosterops lateralis) by analyzing genetic data from mainland and island subspecies in southeastern Queensland, Australia.
  • It reveals that geographic isolation, particularly due to water barriers, plays a crucial role in driving divergence among island populations despite short distances.
  • Findings indicate that while genetic diversity is similar between island and mainland populations, island populations exhibit lower inbreeding, suggesting a unique evolutionary path influenced by their isolated environments.

Extracellular vesicles (EVs) are secreted, cell-derived, membrane-bound compartments implicated in various diseases for their ability to influence distant targets and as carriers of biomarkers. Here, we present a protocol for separating EVs from mammalian pancreatic cancer cells and their characterization using western blot and electron microscopy. We then demonstrate how they are utilized to affect tumor development in a murine model of metastatic pancreatic cancer including a method to quantify hepatic tumor burden in histologic samples.

Estimates of abundance are essential to manage and conserve marine species. Numerous methods are available to determine population size, but the suitability of methods for schooling fishes and the associated precision can vary depending on the species and system. Here, we developed and compared three mark-recapture/resight methods to assess the most robust method to estimate the abundance of silver trevally (Pseudocaranx georgianus).
