Animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal continental shelf ecosystems to polar seas open oceans. Satellite-linked biologgers networks of acoustic receivers allow be reliably monitored over scales tens meters thousands kilometres, giving insight into their habitat use, home range size, phenology migratory patterns biotic abiotic factors drive distributions. Furthermore, environmental variables can collected using as autonomous sampling platforms, increasing spatial temporal coverage global oceanographic observation systems.

Climate change disrupts core habitats of marine species

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(12), P. 3304 - 3317

Published: Feb. 15, 2023

Driven by climate change, marine biodiversity is undergoing a phase of rapid change that has proven to be even faster than changes observed in terrestrial ecosystems. Understanding how these species composition will affect future life crucial for conservation management, especially due increasing demands natural resources. Here, we analyse predictions multiparameter habitat suitability model covering the global projected ranges >33,500 from projections under three CO2 emission scenarios (RCP2.6, RCP4.5, RCP8.5) up year 2100. Our results show core area decline many species, resulting net loss 50% almost half all 2100 high-emission scenario RCP8.5. As an additional consequence continuing distributional reorganization life, gaps around equator appear 8% (RCP2.6), 24% (RCP4.5), and 88% (RCP8.5) with cross-equatorial ranges.

In addition, high invasion rates higher latitudes polar regions lead substantial ecosystem food web structure, particularly regarding introduction new predators. Overall, our study highlights degree spatial structural ensued consequences functionality efforts critically depend on realized greenhouse gas pathway.

Zoonoses are diseases and infections naturally transmitted between humans vertebrate animals. Over the years, zoonoses have become increasingly significant threats to global health. They form dominant group of among emerging infectious (EID) currently account for 73% EID. Approximately 25% originate in domestic The etiological agents include different pathogens, with viruses accounting approximately 30% all zoonotic infections.

Marine Ecosystem Assessment for the Southern Ocean: Birds and Marine Mammals in a Changing Climate

Frontiers in Ecology and Evolution, Journal Year: 2020, Volume and Issue: 8

The massive number of seabirds (penguins and procellariiformes) marine mammals (cetaceans pinnipeds) - referred to here as top predators is one the most iconic components Antarctic Southern Ocean. They play an important role highly mobile consumers, structuring connecting pelagic food webs are widely studied relative other taxa. Many birds establish dense breeding colonies or use haul-out sites, making them relatively easy study. Cetaceans, however, spend their lives at sea thus aspects life cycle more complicated monitor Nevertheless, they all feed reproductive success depends on availability in environment, hence considered useful indicators state resources.

A review of climate change effects on marine mammals in United States waters: Past predictions, observed impacts, current research and conservation imperatives

Climate Change Ecology, Journal Year: 2022, Volume and Issue: 3, P. 100054 - 100054

Published: Feb. 19, 2022

We consider the current evidence of climate change effects on marine mammals that occur in U.S. waters relative to past predictions. Compelling cases such have been documented, though few studies confirmed population-level impacts abundance or vital rates. While many observed had predicted, some unforeseen and relatively acute consequences also documented. Effects often when climate-induced alterations are superimposed upon mammals' ecological (e.g., predator-prey) relationships coincident human activities. As they were unanticipated, unpredicted strained ability existing conservation management systems respond effectively. The literature is replete with suggestive mammals, but which remain unconfirmed. This uncertainty partially explained by insufficient research monitoring designed reveal connections. Detecting mitigating will require realignment priorities, coupled rapid flexible includes both conventional novel interventions.

Seventy years of tunas, billfishes, and sharks as sentinels of global ocean health

Fishing activity is closely monitored to an increasing degree, but its effects on biodiversity have not received such attention. Using iconic and well-studied fish species as tunas, billfishes, sharks, we calculate a continuous Red List Index of yearly changes in extinction risk over 70 years track progress toward global sustainability targets. We show that this well-established indicator highly sensitive responsive fishing mortality. After ~58 extinction, effective fisheries management has shifted the loss curve for tunas whereas continues worsen which are undermanaged. While populations valuable commercial being rebuilt, next challenge halt reverse harm afflicted by these same broad oceanic biodiversity.

Abstract Marine heatwaves cause widespread environmental, biological, and socio-economic impacts, placing them at the forefront of 21st-century management challenges. However, vary in intensity evolution, a paucity information on how this variability impacts marine species limits our ability to proactively manage for these extreme events. Here, we model effects four recent (2014, 2015, 2019, 2020) Northeastern Pacific distributions 14 top predator ecological, cultural, commercial importance. Predicted responses were highly variable across heatwaves, ranging from near total loss habitat two-fold increase. Heatwaves rapidly altered political bio-geographies, with up 10% predicted all shifting jurisdictions during individual heatwaves. The portends need novel solutions that can respond climate As proof-of-concept, developed an operational dynamic ocean tool predicts conditions real-time.
