West Bengal is a maritime state in the northeastern part of the Indian subcontinent with a coastal area of 10,158.22 sq. km. The coastal region consists of the Digha coast, which is noted for its tourism and fish landing activities. We highlight in this paper, a load of nitrate and phosphate during premonsoon in the aquatic phase of Digha for more than three decades (1984 – 2020) to observe the trend of these two variables, which are important components of sewage. A uniform increase in the concentrations of the nutrients is observed except in the years 2009 and 2020. A sudden peak observed for both the nutrients during 2009 may be attributed to Aila, a super cyclone that hit coastal West Bengal on 25th May 2009. The dip in the levels of nutrients during 2020, may be the effect of the COVID lockdown phase in the state during which all the tourism and fish landing activities were completely paralyzed.

Tabasco Chontal is spoken mainly in the coastal area of Tabasco, in the central part of the state north of Villahermosa, and around Macuspana. There are some differences in the speech from area to area. The texts presented here are from the Nacajuca area, northwest of Villahermosa.The texts were written by Plácido Luciano Gerónimo (now about 66), a native Chontal speaker who has lived all his life in the Chontal town of Tapotzingo.Keller encouraged him to write down stories he had heard in the area or knew from boyhood. He recorded the original versions on casette tapes as well as on paper in the 80s and the early part of the 90s, with a free translation into Spanish. Later both authors worked out the semi-literal sentence by sentence translation into Spanish, given here.These stories are part of a larger collection comprised of 22 texts. Keller first went to the Chontal area to live among the people in Tapotzingo and learn the language in 1943, and has been there off and on since then. Together she and Plácido have completed a dictionary, Diccionario Chontal de Tabasco (Mayense), published as number 36 of the Serie de Vocabularios y Dicciona rios Indígenas 'Mariano Silva y Aceves". México: ILV (1997). Other materials published in or about the Chontal language are listed in the bibliography of the dictionary.The first text, "The Story of the Lost Children" is a version in Chontal of "Hansel and Gretel", while the second, "The Story of the Boy Who Was Born from a Chicken Egg", is the story of a baby whose mother finds it too much bother, kills him, grinds him up, and puts his remains in an egg, which she then throws out. An old woman who hasn't been able to have children finds the egg, the child comes back to life again, and she and her husband raise the boy. When he grows up, he finds his biological parents, and turns them into the first deer.

The reproductive ecology of Ameivula ocellifera was studied from September 2009 to August 2010 in a coastal area of the state of Ceará, Brazil. Females reproduced continuously throughout the year, with a peak at the end of the rainy season. Even though there was a predominance of pre-reproductive individuals in the sample, gonadal activity of males peaked synchronously to female reproduction. Mean clutch size was 1.98 ± 0.56 and positively associated with female body size, while mean egg volume was 510.54 ± 84.29 mm3 and unrelated to female body size. We did not find any association between clutch size and average egg volume.

Burmese amber represents the world’s most diverse biota in the Mesozoic. Previous studies have focused on the biodiversity of its inclusions, as well as pholadid borings. Here we report a variety of marine animals symbiotic with or adhere to Burmese amber or the amber deposits, including crinoid columns, corals and oysters. We propose that there is no distinct evidence indicating the secondary transportation of Burmese amber over long distances. The ancient sedimentary environment was likely located in the coastal area. The hardening time of the resin was not long after secretion. The resin has been mixed with fragments of marine organisms in the ancient sediments, and has been deposited for a long time. The zircon age in the sediments surrounding amber approximately represents the age of Burmese amber, but due to limits of the method, the current zircon U-Pb SIMS age may be younger. Therefore, as far as the situation is concerned, the age of Burmese amber may be close to the boundary between the Albian and Cenomanian, or even late Albian. We suggest that it is plausible to generally refer to the age of Burmese amber as mid-Cretaceous, and a precise age requires further biostratigraphic and chronological studies.

The objective of this study was to identify the toxigenic mycobiota and the occurrence of aflatoxins in shrimp feed products intended for shrimp cultivated in the coastal area of the state of Piauí, Brazil, in three farms ("A", "B" and "C"). The toxigenic capacity of the fungal species isolated was tested for aflatoxins (AF) and ochratoxin A production. The fungal counts of shrimp feed were similar for the "A" and "B" farms at all cultivation phases, collection sites, in closed and opened packages (1.33 to 2.66CFU g-1 log10 -1). The lowest fungal counts were found in feed from "C" farm (0.65CFU g-1 log10 -1) from closed packages. Thirty-four strains of Aspergillus were detected with a greater prevalence of A. flavus. Two strains produced B1, B2, G1 and G2 aflatoxins at concentrations from 0.39 to 0.42ng g-1; 0.18 to 0.27ng g-1; 1.78ng g-1 and 0.09ng g-1 respectively and were classified as atypical A. flavus. Two strains of A. niger aggregate were OTA producers. Fifteen samples (13.88%) presented AFB1 contamination at levels ranging from 0.25ng to 360ng g-1. This study demonstrates the presence of toxigenic fungi in shrimp feed used at different phases of cultivation and farms. Atypical strains of A. flavus were isolated which produced AF B1, B2, G1 and G2 in shrimp feeds. Only AFB1 was detected in the analyzed feed

Although fluted points are not very numerous in New York, it was there that they were first recognized as a distinct type under the name of “Seneca River Points” (Beauchamp, 1897, p. 21, Fig. 13, 14).The majority of the New York finds have been in the central section of the state and along the shores of Lake Champlain and Lake George. A search of the literature, and correspondence with both professional and amateur archaeologists, has revealed no known finds of fluted points closer to the coastal area than one at Colonie in Albany County, New York. This was of an exotic quartz (Ritchie, 1951, personal communication). Therefore the finding of a fluted point in eastern Long Island extends the known range of the type.
