Conservation for marine megafaunal predators needs to improve as they are key for ecosystem functioning. We show that different marine predator taxonomic groups have heterogeneous distributions resulting in different spatial conservation priority areas. Current Mediterranean MPAs are failing to sufficiently cover their distributions.

Breaking down silos: Conservation areas for Amazonian flagship terrestrial and freshwater species
This study shows that 17% of the Amazon River Basin is covered by areas of high jaguar density and freshwater migratory species richness, 83% of which are found in Brazil and Peru. A third of these areas are located outside of formal protected areas or Indigenous territories.

ABSTRACT Trammel nets are used with extended soaking times to increase the catching efficiency for demersal fish in commercial fishing. Long soaking time causes deterioration or damage to species caught in the first days. Effects of soaking time were investigated with 36‐mm, 42‐mm, and 46‐mm mesh sizes soaked over 1, 3, 5, and 7 days on target, non ...

ABSTRACT Fishing tourism of sailfish and accompanying species represents a significant source of income for Costa Rica. However, little information is available regarding trends in the availability of these species to recreational fleets. We estimated temporal trends in catch per unit effort (CPUE) for sailfish, marlins, yellowfin tuna, and mahi mahi ...

Types of Linkage of Quadratic Pfister Forms
Given a field $F$ of positive characteristic $p$, $\theta \in H_p^{n-1}(F)$ and $\beta,\gamma \in F^\times$, we prove that if the symbols $\theta \wedge \frac{d \beta}{\beta}$ and $\theta \wedge \frac{d \gamma}{\gamma}$ in $H_p^n(F)$ share the same ...

ABSTRACT The expansion of offshore wind interests in US waters has raised concern over potential adverse impacts to fisheries activity and productivity. Yet evidence‐based platforms for assessing those impacts are lacking for many recreational fisheries.
