Abstract Sea turtles, an ecologically vital marine species, face the mounting threat of plastic ingestion. To devise effective mitigation strategies, a nuanced understanding of the characteristics of ingested plastics is essential. Previous reviews have predominantly concentrated on the frequency of occurrence (%FO) and quantity of ingested plastics. In this study, we present an update to the literature on %FO and quantity of ingested plastics and also introduce a novel review of the morphology, color, and polymer composition of ingested plastics. This analysis draws upon 110 scholarly articles on plastic ingestion by sea turtles. Additionally, we explore geographical variations in both the quantity and characteristics of ingested plastics. Most of the analyzed studies were conducted in the Americas and Europe. We found that approximately 54% of examined sea turtles had ingested plastic debris. Loggerhead sea turtles ingested more foams than green sea turtles (Wilcoxon rank-sum test, p < 0.05). By contrast, green sea turtles exhibited a higher ingestion on films (Wilcoxon rank-sum test, p > 0.05). Our study also underscored the paucity of data regarding the original usage of ingested plastics. White and transparent plastics were most commonly ingested. Additionally, polymers with a lower density than seawater, such as polyethylene, polypropylene, and their copolymers, were frequently found. We strongly advocate for future studies to furnish more comprehensive data regarding the ingested plastics, including quantities, morphological and chemical properties, and origins. Such detailed information is indispensable for shaping well-informed and effective strategies to combat plastic ingestion in marine life.

Abstract Given the important functional roles of sponges in the coral reef community, few studies have looked at sponge community assemblages in Singapore. This study was conducted to assess the sponge diversity, species richness, and species abundance of intertidal sponge communities in Singapore’s coral reefs, including Pulau Hantu, P. Subar Laut, Tanjong Rimau, and Labrador Park. Belt transects measuring 10 m by 1 m were established to survey the sponge communities at these reef sites. Based on sponge morphology, a total of 28 morphospecies were identified, belonging to eight different sponge orders, namely Chondrillida, Clionaida, Dictyoceratida, Haplosclerida, Poecilosclerida, Suberitida, Tetractinellida, and Verongiida. Univariate statistical analyses revealed that sponge diversity, species richness, and abundance at P. Hantu site 2 were significantly higher than that in Labrador Park. In addition, multivariate statistical analyses showed that in terms of community structure, there were three distinct clusters found at P. Hantu site 2, Labrador Park, and P. Subar Laut. The formation of these distinct clusters was sponge species specific and shaped by environmental factors and anthropogenic stresses. Preliminary sponge data presented in this study contribute to the regional biogeography of sponges and could serve as baseline data for future studies, including ecological research and biomonitoring of marine invertebrates, and support marine conservation efforts in Singapore.
