Priority effects, environmental filtering and neutral coexistence explain large...
Barbosa, A. C.C.; Vinagre, Catarina; Kitahara, MV; Flores, A. A. V.Two sun coral species, Tubastraea tagusensis and T. coccinea, have successfully colonized reef habitats along the Southwest Atlantic. However, their invasive biology has been largely addressed without considering species-specific distribution patterns. Here, we assessed the distribution and abundance of Tubastraea spp. at vertical rocky reef sites within a number of islands along 120 km of coastline off the nor...
Shelf and estuarine transport mechanisms affecting the supply of competent larv...
Olaguer-Feliú, A. O.; Flores, A. A. V.; Queiroga, H.; González-Gordillo, J.Supply of competent larvae to the benthic habitat is a major determinant of population dynamics in coastal and estuarine invertebrates with an indirect life cycle. Larval delivery may depend not only on physical transport mechanisms, but also on larval behavior and physiological progress to the competent stage. Yet, the combined analysis of such factors has seldom been attempted. We used time-series analyses to...
Effect of crab size and habitat type on the locomotory activity of juvenile sho...
Almeida, M. J.; Flores, A. A. V.; Queiroga, HenriquePost-settlement processes are a major focus in the study of the dynamics of marine populations and communities. Post-settlement movement of juveniles is an important, but often ignored, process which affects local predator–prey and competitive interactions. We used benthic suction sampling and pitfall traps to examine density and locomotory activity of Carcinus maenas juveniles in different intertidal habitat t...
Tide and wind control of megalopal supply to estuarine crab populations on the ...
Queiroga, Henrique; Almeida, M. J.; Alpuim, T.; Flores, A. A. V.; Francisco, S.; Gonzalez-Gordillo, I.; Miranda, A. I.; Silva, I.; Paula, J.Physical processes that force transport of planktonic larvae of invertebrates are responsible for some of the spatial and temporal variability in recruitment. We investigated the influence of tide- and wind-driven circulation on intra-year variability of megalopal supply to populations of the crab Carcinus maenas in 2 estuaries on the Portuguese west coast. Daily data on physical variables and on supply and set...
