“…De las especies registradas como epizoicas en el Pacífico tropical mexicano, las algas rojas fueron las más diversas, seguidas de las verdes y en menor número las pardas, así como las cianobacterias. Esta relación proporcional entre los diferentes grupos algales coincidió con lo registrado por otros autores para los inventarios florísticos en localidades de distintos estados del Pacífico tropical mexicano (Mateo-Cid y Mendoza-González, 1991, 2012Pedroche y Sentíes, 2003a, b;Vega et al, 2008;Dreckmann et al, 2006;Mendoza-González et al, 1994, e inclusive en las costas del Pacífico donde un estudio a largo plazo demostró que Rhodophyta fue la división más diversa, la cual alcanzó 66.6% (Lin et al, 2018). Las algas rojas presentan un marcado cambio en su riqueza desde el ecuador hasta mares más fríos, siendo mayor en las zonas tropicales (Lee, 2008), de la misma manera que se presenta en la ficoflora del Pacífico tropical mexicano.…”

Antecedentes y Objetivos: El conocimiento ficológico para la región del Pacífico mexicano es amplio, la mayoría de los estudios han estado orientados a conocer la flora adherida a sustratos rocosos. Sin embargo, es reducido el número de trabajos acerca de macroalgas que crecen sobre organismos vivos, como las algas epizoicas. El presente trabajo tiene como finalidad contribuir al conocimiento de la flora algal epizoica en el Pacífico tropical mexicano. Métodos: Se llevaron a cabo cuatro muestreos del molusco Chiton articulatus en dos localidades de Guerrero, México, durante 2014, para conocer las algas que crecen sobre él. Además, se realizó una revisión bibliográfica de estudios en el Pacífico tropical mexicano para obtener los registros de las algas que crecen sobre animales. Finalmente, se determinaron las algas en los moluscos mediante observaciones de talos completos y cortes. Resultados clave: En total se reportaron 124 especies, 81 géneros, 51 familias y 27 órdenes, distribuidos en cuatro divisiones de algas. Los órdenes con mayor riqueza específica fueron Ceramiales (23) y Corallinales (20) y las familias con mayor número de especies fueron Rhodomelaceae (13), Cladophoraceae (11) y Lithophyllaceae (10). Los géneros más diversos fueron Amphiroa y Cladophora (7). Se presentan, para Guerrero, 12 nuevos registros de especies, de los cuales tres son además nuevos registros para el Pacífico tropical mexicano y tres para el Pacífico de México. El estado con mayor número de especies registradas fue Guerrero (58). El sustrato más común fueron los moluscos. El grupo morfofuncional algal predominante fue los filamentos.Conclusiones: Los resultados de este trabajo demuestran que la biodiversidad de algas presente en los sustratos animales es alta, y contribuye notablemente a la riqueza específica registrada para Guerrero y para el Pacífico de México. Se hace patente la importancia de desarrollar más estudios que se enfoquen al conocimiento de la epibiosis algal.

“…Several studies reported that the water masses of the CCC plays an important role in transporting marine creatures to coastal waters of Taiwan, such as copepods [52], jellyfish [53–55], zooplankton in general [56], and affects the communities of macroalgae [57]. The calanoid copepod, Calanus sinicus , provides an example that demonstrates that the CCC drives it from the Yellow Sea and the Bohai Sea to the southern East China Sea area, and to Hong Kong [58].…”

The present study recorded the population of the goby fish (Perciformes: Gobiidae), Eutaeniichthys cf. gilli Jordan & Snyder, 1901, from the tunnel burrowed by the mud shrimp Austinogebia edulis Ngo-Ho and Chan, 1992 in a mudflat in Shengang and Wangong of Changhua County, western Taiwan. This finding is not only a new record of the genus in Taiwan, it is also the first record of this species in a mudflat near an industrial park. In total, 56 individuals of E . cf. gilli were collected from June 2016 to September 2018. Morphological traits of males and females were measured. The resin casting method trapped bodies of E . cf. gilli that were present in the tunnel burrow and proved that the fish inhabits burrows of the mud shrimp A . edulis . In addition, a species of snapping shrimp was also found in the same tunnel. Symbiotic interaction may occur between E . cf. gilli , A . eduli and the snapping shrimp. The China Coastal Current (CCC) runs along the coastlines of Japan, Korea, China, and reaches western Taiwan during the northeast monsoon period. The CCC, therefore, might play an important role in the biogeographic distribution of E . cf. gilli in the western Pacific Ocean. Since E . cf. gilli is listed in the Red List as an endangered species of Japan for many years, Taiwan waters may provide a refuge for this fish species warranting a broader investigation. Since Taiwan is some distance away from the previously recorded locations in Japan, Korea, the Yellow Sea, and the Bohai Sea, a phylogenic analysis is warranted for population and species differentiation in the future.

“…Diverse sources of sounds affect the composition of the acoustic environment of both areas. The northeast monsoon in winter and the southwest monsoon in summer are the primary factors affecting the wind and current variations around Taiwan [ 45 ]. Every year the ETS experiences several tropical storms, accompanied by strong wind speeds.…”

A Complexity-Entropy Based Approach for the Detection of Fish Choruses

Automated acoustic indices to infer biological sounds from marine recordings have produced mixed levels of success. The use of such indices in complex marine environments, dominated by several anthropogenic and geophonic sources, have yet to be understood fully. In this study, we introduce a noise resilient method based on complexity-entropy (hereafter named C-H) for the detection of biophonic sounds originating from fish choruses. The C-H method was tested on data collected in Changhua and Miaoli (Taiwan) during the spring in both 2016 and 2017. Miaoli was exposed to continual shipping activity, which led to an increase of ~10 dB in low frequency ambient noise levels (5–500 Hz). The acoustic dataset was successively analyzed via the acoustic complexity index, the acoustic diversity index and the bioacoustic index. The C-H method was found to be strongly correlated with fish chorusing (Pearson correlation: rH < −0.9; rC > 0.89), and robust to noise originating from shipping activity or natural sources, such as wind and tides (rH and rC were between 0.22 and −0.19). Other indices produced lower or null correlations with fish chorusing due to missed identification of the choruses or sensitivity to other sound sources. In contrast to most acoustic indices, the C-H method does not require a prior setting of frequency and amplitude thresholds, and is therefore, more user friendly to untrained technicians. We conclude that the use of the C-H method has potential implications in the efficient detection of fish choruses for management or conservation purposes and could help with overcoming the limitations of acoustic indices in noisy marine environments.
