“…Based on species occurrence, biogeographic affinities and provinciality were determined by Parsimony Analysis of Endemism (PAE). This analysis is the most widely used parsimonybased tree algorithm, which from presence/absence distribution data reproduce historical relationships between areas based on species distribution and segregate areas where endemism most possibly evolves (Aguilar-Medrano, Reyes-Bonilla, & Polly, 2015;Casagranda, Taher, & Szumik, 2012;Contreras-Medina, Luna-Vega, & Morrone, 2007).…”

The Laguna Madre Tamaulipas (LMT) is the largest hyperhaline coastal lagoon of Mexico, is diverse and provides a wide range of services, besides its economic importance for local and national fisheries. However, due to global and local pressures, the fish community is under stress. Here we study the LMT fish community to determine its biogeographical affinities with the Gulf of Mexico and Caribbean, understand its trophic relationships and habitat distribution, and to analyze the fisheries pressures in specific habitats and trophic groups (TGs). Our biogeographical analyses based on Parsimony Analysis of Endemism produce three provinces Center, South, and Northern, being this last the most related to the LMT, thus activities in this and the LMT directly affect each other. Through a nested cluster analysis using trophic values and size, 15 TGs were found, being the small‐species the most diverse and the largest the less diverse and most targeted by fishermen, which put on risk its ecological role and may provoke cascading effects on many species and processes. As well, mangroves and oyster banks habitats are supporting most of the fisheries. This is the first study of the whole fish community of the LMT, we pinpoint provinces, habitats, and TGs that need special attention and constant monitoring to generate integrative management plans that fit the actual needs of the community and prepare it to buffer future changes.

“…The CBS, GM, and ATL were segregated into eight zones according to Allen (1991): Gulf of Mexico; Florida; Bermuda; North Caribbean Sea; South Caribbean Sea; St. Helena/Ascension; Cape Verde Islands; and West Africa. The EP was segregated into six zones according to Aguilar-Medrano et al (2015): North (Revillagigedo, Gulf of California, Mexican Province, and Guatemala); Center (El Salvador, Nicaragua, Panama, Costa Rica, and Colombia); eastern Pacific Equatorial Islands (Galapagos, Malpelo, and Coco); South (Ecuador, Peru, and Chile); California Province; and Clipperton Island.…”

“…Ecological variables such as habitat, food availability, ocean temperature, and productivity strongly influence the distribution and evolution of marine organisms (Grove et al 1986;Bellwood et al 2004;Price et al 2011;Lobato et al 2014). Pomacentrids inhabit a wide range of habitats (Clarke 1971;Grove et al 1986;Robertson and Allen 2015;Aguilar-Medrano et al 2015, 2016. In the eastern Pacific (EP), 24 species of damselfish have been recorded between Monterey Bay, California in the North and the coast of Valdivia, Chile in the South (Cooper 1863;Allen 1991;Pequeño et al 2005).…”

The vicariance model of biogeography focuses on allopatric speciation through fragmentation from an ancestral biota via a barrier that interrupts gene flow between populations. The evolutionary processes that occur over time in sister species on each side of the vicariance event influence their traits by a compromise between divergence and conservatism. The eastern Pacific and the Caribbean Sea were separated by the Isthmus of Panama ~ 3-6 Mya and allopatric speciation occurred on either side of the isthmus. Differences in ecological conditions on each side of the Isthmus of Panama separating the sister species may have shaped their niches and morphologies over evolutionary time. The objectives of this study were to: (1) analyze the variation in niche, morphology, and size in each pair of sister damselfish species on both sides of the Isthmus of Panama, (2) determine whether these variables show specific patterns on each side of the isthmus, and (3) determine whether these variables are correlated through evolution. The results showed no relationship between morphology and niche, however, size was related to both niche and morphology. Sister damselfish species on either side of the Isthmus of Panama differ in terms of niche, morphology, and size. Nevertheless, they also show similarities, indicating environmental constraints and conservatism. This study describes a model in which adaptation or divergence and conservatism shaped the evolution of sister damselfish species on both sides of the Isthmus of Panama. These mechanisms are fundamental to population biology, and they act in opposite directions.

“…Tropical, subtropical and temperate near‐shore waters around the world provide important habitats for the widely distributed species of the damselfishes or anemonefishes, family Pomacentridae (Allen, ), representing one of the most diverse radiations among reef fishes (Aguilar‐Medrano et al, ; Aguilar‐Medrano et al, ; Aguilar‐Medrano et al, ; Cooper & Westneat, ; Frédérich et al, ; Frédérich & Vandewalle, ). The majority of pomacentrids inhabit the Indo‐west and central Pacific Oceans, living mainly in coral‐reef environments, although a number of species inhabit rocky reefs and kelp forests across temperate waters of the Atlantic Ocean or eastern Pacific Ocean (Allen, ).…”

“…Nevertheless, a broad diversity of adult and larval traits associated with behaviours and trophic guilds (i.e. planktivory, herbivory, omnivory), have been described within Pomacentridae (Aguilar-Medrano et al, 2011;Aguilar-Medrano et al, 2013;Aguilar-Medrano et al, 2015;Frédérich et al, 2013;Frédérich & Vandewalle, 2011).…”

Embryonic development and larval morphology of Chromis crusma was described from five nests sampled between 21 and 25 m depth in central Chile (33°S). From each nest, a set of c. 100 randomly selected eggs were hand‐collected and transported in seawater to the laboratory. Subsets of c. 30 eggs per nest were maintained in 50 ml glass containers at a constant ambient temperature of c. 12°C (range 11.5–12.9°C). Egg length (L) and width (W) and larval notochordal length (LN) were measured from photographs. Geometric morphometric analyses were performed in newly hatched and 1 week old larvae to quantify shape changes. Ellipsoid eggs had an average (mean ± SE) size of 1.12 ± 0.05 mm L and 0.67 ± 0.02 mm W, with volume being similar throughout 15 developmental stages (i.e., ellipsoid‐shaped; 0.27 mm3). Planktonic larvae hatched between 5 and 11 days at 12°C and had a mean LN of 3.13 ± 0.25 mm, a yolk sack volume of 0.03 mm3 and an oil droplet volume of 0.005 mm3. Morphological traits at hatching included: (a) lack of paired fins and jaws; (b) single medial fin fold; (c) lack of eye pigmentation; (d) yolk sac present near anterior tip; (e) melanophores distributed along ventral surface with one pair over the forehead. In order to generate an up‐to‐date summary of developmental traits within Pomacentridae, we reviewed literature on egg development (e.g., shape and number of oil droplets), hatching and larval traits (e.g., morphology, pigmentation patterns). Thirty‐two publications accounting for 35 species were selected, where eggs, embryonic development, hatching and larval traits were found for 26, 21, 24 and 34 species, respectively. In order to evaluate potential phylogenetic and environmental relationships within the early stages of Pomacentridae, cluster analyses (Bray Curtis similarity, group average) were also performed on egg and larval traits of 22 species divided by subfamily (Stegastinae, Chrominae, Abudefdufinae, Pomacentrinae) and thermal ranges (i.e., low: 16.5°C (range: 12–21°C), medium: 24.5°C (range:21–28°C) and high: 27°C (range: 26–28°C)), suggesting that early developmental patterns can be segregated by both temperature and phylogenetic relationships.
