Citizen-science driven exercises (e.g., bird surveys) and online platforms (e.g., eBird) provide voluminous data on bird occurrence but the data quality is often compromised. Bird atlases are based on standardized surveys and describe the distribution of bird species over a predefined region and have less biases, and thus are better suited for use...

Many species of birds are known to collect and incorporate mammalian hair into their nests, presumably to augment their reproductive success. Birds source it from dead animals, shed hairs, and even live animals. Here, we report theft of hair (kleptotrichy) from a live cow by 2 Large-billed Crows (Corvus macrorhynchos culminatus) in India, along wit...

Debris accumulation in natural ecosystems is one of several anthropogenic stressors exerting pressure on ecosystems all around the world. Effects of the ubiquitous anthropogenic debris pollution on free-living organisms is well known. Increasing reports of anthropogenic debris in nests of several species of birds ranging from terrestrial to seabird...

Abstract Corvids have long impressed scientists with their flexibility in problem-solving and innovative tool use. Opportunistic observations of five wild house crows (Corvus splendens), a couple of them approaching burning oil lamps and delicately lifting the flaming wick and extinguishing it to consume the cotton wick are reported here. Although...

The Red-eared Slider (RES), Trachemys scripta elegans (Wied, 1838), is a highly sought-after pet (Herrel and van der Meijden, 2014) and introduced freshwater turtle worldwide (García-Díaz et al., 2017; Seebens et al., 2017). This species has successfully established populations in all continents except Antarctica (Meyer et al., 2015; Dupuis-Desorme...

The Grey Heron Ardea cinerea is a large wading bird indigenous to temperate areas of Europe, Asia and Africa; it plays a vital role as an environmental indicator due to its status as a top predator in freshwater ecosystems. Despite the presence of numerous heronries in India, breeding records for this species are notably limited. This study reports...

Microplastics (MPs) pollution has become a significant environmental concern globally, with emerging evidence indicating their widespread presence in marine ecosystems. Among the diverse range of aquatic organisms affected by MPs, shrimp occupy a crucial ecological niche and serve as a valuable food source for marine predators and human consumption...

The Megamouth Shark (Megachasma pelagios), considered rare, has been observed in increased records recently, surpassing 273. The present study provides insight into the limited Indian Ocean records by reporting a specimen collected in Sakthikulangara Harbour, Kollam, Kerala, India. It highlights the need for monitoring and improved research to bett...

The Western Ghats, a UNESCO World Heritage site, is home to the freshwater Myristica swamps, which thrive in acidic, waterlogged conditions in Karnataka, Kerala, and Tamil Nadu. Myristica trees, essential for maintaining the ecosystem, are vital for its integrity. A study comparing bacterial diversity in sediment samples from Myr istica swamp patch...

The Common Myna (Acridotheres tristis) is a frequently observed flocking bird of urban habitats. This paper presents opportunistic observations of two bald Common Mynas from distinct locations in Kerala. While bald Common Mynas have been documented in various regions of India, this paper discusses the first occurrences reported in Kerala. Notably,...

The cestode family Gymnorhynchidae (Trypanorhyncha) comprises three genera and six valid species that, as adults, are all intestinal parasites of large pelagic sharks. Their life cycle has not been elucidated yet, but it has been proposed that copepods serve as first, pelagic euphausiids or schooling fish as second, and larger predatory fishes as t...

Microplastics (MPs) have been identified in diverse settings, including drinking water, freshwater, food, air, and marine environments. This study employed stereomicroscopic and µ-Raman techniques to analyze water samples from ten widely consumed bottled water brands, aiming to detect and characterize MPs. Additionally, the oral consumption of MPs...

The Laughing Dove Spilopelia senegalensis had previously not been recorded in Kollam, Kerala, India; the sighting reported here was made on 2 December 2023.

This letter reports a novel observation of terrestrial foraging behavior by the Indian Pond Heron (Ardeola grayii), highlighting its adaptability and resourcefulness in exploiting diverse food sources. The study documents the heron’s unusual feeding habits in Kollam Beach, India, where it demonstrates a preference for terrestrial environments despi...

Necropsy on a striped dolphin Stenella coeruleoalba (Meyen, 1833) entangled in ghost fishing net and dead while rescuing yielded some helminth parasites, later identified as Halocercus lagenorhynchi. DNA barcoding of the host and parasite and the phylogenetic analysis of the parasite was conducted. This study provides valuable information towards e...

The tropical and subtropical coastal plains are known for harboring mangroves, which represent one of the most remarkable and distinctive ecosystems globally. These ecosystems are formed through the mutual interaction between emergent land plants and sediment microbiomes. The rhizosphere of mangroves and the adjacent sediments host a diverse range...

Abstract Saraca asoca is an important tropical medicinal plant mainly found in the Western Ghats of India. It is a small evergreen tree, belongs to the family Fabaceae. It is commonly known as the "Ashoka". Traditionally, it is used in the treatment of various gynaecological disorders, dyspepsia, diseases of the blood, biliousness, tumors, abdomina...

Despite the invaluable ecosystem services provided by the wetlands and the wetland birds, the habitat that is grappling with the reverberations of climate change is increasingly subjected to anthropogenic disturbances worldwide and is deteriorating and decimated incessantly. The present study was conducted in the Indian state of Kerala on the South...

The article discusses the Kerala Bird Atlas (KBA), Asia's largest bird atlas, which systematically surveyed bird species distribution across the state of Kerala, India. The KBA dataset provides valuable information on bird occurrence, species richness, and conservation priorities, making it a valuable resource for ecological research and science-ba...

Efficacy of three marine yeasts (Debaryomyces hansenii S8, Debaryomyces hansenii S100 and Candida tropicalis S186) as feed supplement for Penaeus indicus was estimated in comparison with Saccharomyces cerevisiae MTCC 36, a commercial feed (Higashi Maru Feeds, India) and a control feed. The yeast component of control feed was replaced with Carboxy M...

A male striped dolphin, was found entangled in discarded fishing net, off Tangassery, Coast, Kollam, Kerala, India (8°52′55″N76°34′26″E) by the Coastal Police Patrol to be identified later, as Stenella coeruleoalba. The trapped animal was in a state of fatigue ensued by the struggle to free itself from the ensnaring monofilament driftnet. Necropsy...
