Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

open access: yesConservation Biology, EarlyView.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.
