Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

The complete mitochondrial genomes of two octopods Cistopus chinensis and Cistopus taiwanicus: revealing the phylogenetic position of the genus Cistopus within the order Octopoda. [PDF]

open access: yesPLoS ONE, 2013
In the present study, we determined the complete mitochondrial DNA (mtDNA) sequences of two species of Cistopus, namely C. chinensis and C. taiwanicus, and conducted a comparative mt genome analysis across the class Cephalopoda.

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, EarlyView.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and
