Sea turtles in the Atlantic and Indian Oceans, a step towards understanding byc...
Domingo, Andrés; Baéz, José Carlos; Miller, Philip; Parker, Denham; Ramos, María Lourdes; Sabarros, Philippe S.; Brown, Craig; Camiñas, Juan AntonioKnowledge of the spatiotemporal behavior and interactions with fishing gear of bycatch species is essential to improve conservation and fisheries management strategies. We analyze fine-scale data from onboard observers, covering 25 fishing fleets from 2002 through 2018, to assess temporal trends and spatial variation in sea turtle bycatch in longline and purse seine tuna fisheries in the Atlantic and Indian oce...
Spatial and temporal size distribution of swordfish in the Atlantic Ocean: impl...
Rosa, Daniela; Schirripa, Michael; Gillespie, Kyle; Macías, David; Forselledo, Rodrigo; Mourato, Bruno; Kai, Mikihiko; Arocha, Freddy; Su, Nan-JaySwordfish (Xiphias gladius) is a common target species of surface pelagic longline fisheries. In the Atlantic Ocean and Mediterranean Sea, swordfish is managed as three separate stocks, all having management measures in place to rebuild or conserve the stocks, including minimum landing sizes. The objective of this study was to review size data for swordfish in the Atlantic Ocean, model the sex-specific size dis...

CD155/PVR determines acute myeloid leukemia targeting by Delta One T cells
Mensurado, Sofia; Condeço, Carolina; Sánchez-Martínez, Diego; Shirley, Sara; Coelho, Rui; Tirado, Néstor; Vinyoles, Meritxell; Blanco Dominguez, RafaelRelapsed or refractory acute myeloid leukemia (AML) remains a major therapeutic challenge. We have recently developed a Vδ1+ γδ T cell-based product for adoptive immunotherapy, named Delta One T (DOT) cells, and demonstrated their cytolytic capacity to eliminate AML cell lines and primary blasts in vitro and in vivo. However, the molecular mechanisms responsible for the broad DOT-cell recognition of AML cells r...
Blue shark (Prionace glauca) movements, habitat use, and vertical overlap with ...
Mas, Federico; Cortés, Enric; Coelho, Rui; Defeo, Omar; Miller, Philip; Carlson, John; Gulak, Simon; Domingo, AndrésOver the last three decades, the advent and the continuous sophistication of telemetry devices have revolutionized our understanding of how pelagic sharks move and exploit their three-dimensional underwater habitat, with implications for management and conservation. In this study, conventional (4,648) and electronic (18) tags were used to assess the horizontal and vertical movements of blue sharks, Prionace gla...
Management strategy evaluation operating model conditioning: a swordfish case s...
Mosqueira, Iago; Fu, Dan; Coelho, Rui; Rosa, DanielaEvaluation of fish stock status is a key step for fisheries management. Tuna Regional Fisheries Management Organizations (t-RFMOs) are moving towards management strategy evaluation (MSE), a process that combines science and policy and depends on technical aspects, developed by scientists, designed to meet management objectives established by managers and other stakeholders. In the Indian Ocean, the current mana...
Challenges and opportunities in monitoring and mitigating sea turtle bycatch in...
Baéz, Jose Carlos; Domingo, Andrés; Murua, Hilario; Macías, David; Camiñas, Juan Antonio; Poisson, Francois; Jorda, María José Juan; López, JonFisheries that target tunas and tuna-like species are managed by tuna regional fisheries management organizations (t-RFMO) and are known to interact with various bycatch species, including sea turtles, with potentially negative effects. Actions and management measures implemented by t-RFMO to monitor sea turtle fisheries interactions, reduce their bycatch in fisheries, and carry out best practices for the handl...
Global habitat predictions to inform spatiotemporal fisheries management: initi...
Bowlby, Heather D.; Druon, Jean-Noël; Lopez, Jon; Juan-Jordá, Maria José; Carreón-Zapiain, María Teresa; Vandeperre, Frederic; Leone, AgostinoTuna Regional Fishery Management Organizations (tRFMOs) are increasingly interested in spatiotemporal management as a tool to reduce interaction rates with vulnerable species. We use blue shark ( Prionace glauca ) as a case study to demonstrate the critical first steps in the implementation process, highlighting how predictions of global habitat for vulnerable life stages can be transformed into a publicly -acc...
Leader material and bait effects on target and bycatch species caught in an Atl...
Casaca Santos, Catarina; Santos, Miguel N.; Rosa, Daniela; Coelho, RuiThe influence of bait type and leader material on target and bycatch species was assessed through fishing experiments in the Portuguese shallow pelagic longline fishery in the Atlantic Ocean. Wire leaders were found to decrease catch rates of commercially valuable species such as bigeye tuna and yellowfin tuna, while increasing catch rates of elasmobranchs, including the blue shark and shortfin mako. The odds r...
The potential fish provisioning services of vegetated and unvegetated habitat i...
Erzini, Karim; Sadat, Zineb; Bentes, Luis; Coelho, Rui; Lino, Pedro; Monteiro, Pedro; Oliveira, Frederico; Ribeiro, Joaquim; Gonçalves, Jorge M.S.The potential fish provisioning services of the Ria Formosa lagoon (Portugal) were calculated for single cohorts of 7 commercially fished species, based on densities of juveniles sampled with beach seines on a monthly basis over a 17-month period at 41 locations. The potential maximum yield per recruit (F0.1 criteria) was calculated for vegetated (V) and unvegetated (UV) habitat for low and high natural mortali...
