“…In this study, we found that increasing species diversity (Pawluk et al, 2021) is associated with increasing functional richness, but stable or decreasing functional dispersion (Figure 2). The trait analysis indicated that these trends were predominantly driven by increasing prevalence of large, long‐lived, later‐maturing, and warm‐water‐associated species (Figure 3).…”

“…Along the Texas coast, as in many marine ecosystems (Collie et al, 2008; Hiddink & Ter Hofstede, 2008; Perry et al, 2005), climate change has led to shifts in the spatial distributions and abundances of invertebrates and fishes that yield an overall increase in species diversity (Fujiwara et al, 2019; Pawluk et al, 2021). While biodiversity is often thought to confer benefits on ecosystem functioning through a positive correlation with functional diversity (Hooper et al, 2005), the relationship between species and functional diversity often differs across ecosystems and functions considered (Cadotte et al, 2011).…”

“…While a meta‐analysis of coastal survey data by Pinsky et al (2013) found that climate velocity (the rate and direction of climate shifts) significantly explained fish and invertebrate distribution shifts. Many such distribution shifts and expansions have led to increasing fish species diversity in temperate and subtropical ecosystems (Fujiwara et al, 2019; Hiddink & Ter Hofstede, 2008; Pawluk et al, 2021). As novel communities are formed due to range shifts, novel interactions between native and invading species are potentially produced (Van der Putten et al, 2010).…”

“…Biodiversity is a critical community parameter for conservation and management because of favorable linkages with e cient variation and redundancy, hence with environment stability, exibility, and effective (Pawluk,et al 2020). In the previous four decades, oceans and seas have lost over 1% of their biodiversity per year (WWF, 2016).…”

Marine sh biodiversity and conservation linking to human livelihood around the coast were carried out during 2019 by survey and personal interviews to study the effects of environmental and anthropogenic issues on marine sh diversity changes which affect the sustainability. 42 n sh, 6 crabs, and 1 shrimp belonging to 3 groups collected along the coastal zone were authenticated by Zoological Survey of India (ZSI). The sh species diversity index was estimated showed that alpha and beta biodiversity were prevalent compared to gamma sh diversity in the study zone. The collected sh species were compared with International Union for Conservation of Nature (IUCN) threatened lists and found 51% least concerned. The Principle Component Analysis done for the livelihood status age group, religious, education, houses, training, graft and gear of shermen exhibited 93.6% and 4.3% variations. The observed 51% least concerned species in the study zone implies species declination due to overexploitation of the natural sources. The study recommends strict conservation measures to be implemented to ensure sustainability and conservation of sh diversity. The sh conservation is a crucial factor for the sustainability of the human lively hood

“…This is because species richness tends to decline from the equator to the poles (Rabosky et al, 2018;Willig et al, 2003). For example, previous studies in the northwestern Gulf of Mexico detected an increase in species diversity and changes in the incidence of fish and invertebrate species over time Pawluk et al, 2021). As the species diversity increases, the community composition, as well as functional diversity, changes (Pawluk et al, 2022); however, how these changes that resulted from climate change still remain to be investigated.…”

Life‐history traits and temporal patterns in the incidence of coastal fishes experiencing tropicalization

Climate change is causing shifts in the geographic distributions of coastal fish species toward higher latitudes. However, local fish communities found in higher latitudes today are not simply those found in lower latitudes in the past because the sensitivity of species to various environmental conditions is different. Responses of fish to environmental conditions differ depending on their life-history traits such as the maximum population growth rate, age of maturity, and generation time because these traits are constrained by environmental conditions. Here, we investigate associations among temporal patterns in presence-absence (incidence) data, life-history traits of species, and environmental conditions to elucidate the potential mechanisms behind the effects of climate change on coastal fish communities. In this study, fish monitoring data collected semi-monthly between 1982 and 2019 from eight major bays in the northwestern Gulf of Mexico were analyzed with generalized additive models. Smooth patterns over seasons and years in the incidence data of 77 species were estimated, and the data were associated with environmental variables. Further, these temporal patterns were associated with the life-history traits of species. The results show that species that are more common in the summer months (non-winter spawners) tend to exhibit an increasing trend and that species common during the spring (winter spawners) tend to exhibit a decreasing trend, suggesting the importance of summer conditions in driving tropicalization. Salinity had significant effects on species in general, and longer-lived species tended to be affected by temperature. These results suggest seasonal differences in the effects of environmental conditions and variation in sensitivity to environmental conditions among different life-history strategies. These findings represent major steps toward understanding the mechanisms behind the tropicalization of estuarine communities.
