“…La dominancia numérica de pocas especies en la ictiofauna lagunar somera encontrada en este trabajo (familias Engraulidae, Gerreidae y Mugilidae), ha sido reportada también por varios autores en otras zonas estuarinas de México (Castillo-Rivera et al 2010, Mendoza et al 2009) y en sistemas estuarinos tropicales y subtropicales de otras regiones de América (Ley et al 1999, Barletta et al 2003, Greenwood et al 2006, Lewis et al 2011. Esta estructura general de la ictiofauna estuarina ha sido considerada una regularidad (Whitfield 1999) que se puede explicar porque no son muchas las especies capaces de tolerar los amplios cambios ambientales que ocurren estacionalmente en los sistemas estuarinos, pero aquellas que son euritópicas, encuentran condiciones excelentes de alimento y refugio, lo que les permite existir con gran abundancia.…”

Contemporary and historical influences on the genetic structure of the estuarine-dependent Gulf killifish Fundulus grandis

In comparison to species living in open marine environments, estuarine-dependent species are expected to exhibit stronger genetic population structure due to dispersal limitations. Estuarine habitats are relatively transitory on geological time scales; thus, populations may not be at migration-drift equilibrium, which could confound estimates of current day gene flow or selection. We used 8 nuclear microsatellite loci to investigate the genetic structure of the estuarine Gulf killifish Fundulus grandis across 10 populations along the northwestern and northeastern Gulf of Mexico. Patterns of isolation by distance, spatial autocorrelation, and assignment tests indicate that dispersal is limited and occurs primarily between neighboring sites. Principal component analysis and Bayesian clustering revealed evidence for genetic discontinuities located in Mobile Bay and western Florida which are near hypothesized biogeographical boundaries. There was also a significant negative relationship between genetic diversity and latitude, a pattern consistent with the presence of hypothesized refugia in the southern Gulf regions during the Pleistocene that later recolonized the northern Gulf. Results suggest that populations may be at or near migration-drift equilibrium at a regional scale (e.g the western Gulf), but that dispersal barriers and potential historical signatures on population structure will need to be taken into consideration at larger spatial scales.

“…Similarly, Lassig's (1983) time series data showed little effect of a tropical cyclone on adult fishes, but a notable effect on recruits -findings likely unattainable with only data 'snapshots.' More recently, however, issues of temporal scale have been addressed as more multi-year datasets are becoming available, and more studies have been able to address disturbances (e.g., Greenwood et al 2006. Multi-year studies provide data from before and after disturbance events that allow documentation of disturbance effects because the studies provide pre-and post-disturbance data.…”

Effects of a Severe Cold Event on the Subtropical, Estuarine-Dependent Common Snook, Centropomus undecimalis

The effects of infrequent disturbance events on marine fishes are often difficult to determine, due largely to lack of sufficient pre-and post-disturbance event data. In January 2010, subtropical southwestern Florida (USA) experienced extreme cold for 13 days, which caused extensive mortality of many fish species. The effect of this severe cold event on common snook (Centropomus undecimalis), an economically important gamefish, was assessed using three years (2007)(2008)(2009)) of pre-event and one year (2010) of post-event data from a tag-recapture program conducted over 28 km of Gulf of Mexico barrier islands of Florida. All metrics pointed to a significant effect of the severe cold event: post-disturbance apparent survival of marked fish was 96-97% lower than pre-disturbance, and post-disturbance common snook abundance was 75.57% and 41.88% less than in 2008 and 2009, the two years immediately pre-event. Although severe cold events have impacted subtropical Florida in the past, these events are infrequent (the previous recorded event was >30 years prior), and documentation of the impacts on common snook have not previously been published.
