Marine protected areas can increase the abundance of invasive lionfish (Pterois miles)

Conservation Science and Practice, Journal Year: 2024, Volume and Issue: 6(6)

Published: June 1, 2024

Abstract Marine protected areas (MPAs) can protect and restore marine biodiversity fisheries, but there are concerns that they may also benefit invasive species. The spatial temporal colonization of lionfish ( Pterois miles ) in the eastern Mediterranean was compared across zones with varying fishing restrictions (no fishing, recreational commercial only), stations where targeted removal events were conducted by volunteer SCUBA divers. Lionfish density no nearly double only, over four times greater than both allowed. increased depth, possibly due to easier human exploitation shallow waters (0–10 m) accessible spearfishers. Targeted removals divers decreased densities 60%, while without had a 200%–400% increase. Along management actions, natural ecological processes might drive within MPAs, speed which colonized fishery‐restricted zones, emphasized need for more sophisticated MPA strategy considers species impacts dynamics an ecosystem‐based approach.

An underwater clash of spears: Public engagement in Mediterranean lionfish control efforts

Abstract Invasive alien species pose a great challenge in conservation ecology. Rapid establishment of common lionfish ( Pterois miles ) the eastern Mediterranean Sea and its ongoing westward expansion raises many questions about how to sustainably combat this invasion long term. Drawing on experiences from western Atlantic invasion, citizen scientists were engaged demonstrated efficiency long‐term coordinated removals for first time Sea. Findings reveal sustained participation interest throughout removal events that encourage organization future events. Removal Action Teams found effective at reducing numbers small (less than half hectare) areas high value, when repeated systematically. Single‐day derbies, operated greater spatial scales, succeeded 50% reduction abundance while removing most large (>30 cm) individuals an area after three consecutive Given recreational character such activities, are useful options management guided by competent authorities supported citizens, as they promote marine environmental awareness help develop sense stewardship among members public.

Variation in Oceanographic Resistance of the World's Coastlines to Invasion by Species With Planktonic Dispersal

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(9)

Published: Sept. 1, 2024

ABSTRACT For marine species with planktonic dispersal, invasion of open ocean coastlines is impaired by the physical adversity currents moving larvae downstream and offshore. The extent are affected depends on interactions larval life history traits such as duration, depth seasonality. Ecologists have struggled to understand how these expose adverse affect their ability persist when introduced novel habitat. We use a high‐resolution global model isolate role persistence larval‐producing every coastline world. find varies globally several orders magnitude. Larval duration most influential trait because increased prolongs species' exposure currents. Furthermore, variation elucidates trade‐offs between dispersal vary globally.
