Fission or fusion: shoaling adaptations in green chromides ( <i>Etroplus suratensis</i> ) across multiple manipulations Open
Collective behaviour contributes towards increased fitness, however, in fission-fusion societies, the decision to participate in a group is based on cost-benefit ratio derived under a given condition. In today’s world, this ratio dramatica…
Understanding feeding competition under laboratory conditions: Rohu (<i>Labeo rohita)</i>versus Amazon sailfin catfish (<i>Pterygoplichthys</i>spp.) Open
Competitive interactions between species is widely prevalent within the animal world. In this manuscript, we attempted to understand feeding competitions between the Amazon sailfin catfish, an invasive species introduced globally, and rohu…
Monitoring the stress physiology of free-ranging mugger crocodiles (<i>Crocodylus palustris</i>) across diverse habitats within Central Gujarat, India Open
Animals face several challenges in their natural environment, and to cope with such conditions, they may exhibit contrasting physiological responses that directly affect their overall well-being and survival. In this study, we assessed phy…
Ecological assessment of the Amazon sailfin catfish (<i>Pterygoplichthys</i>species) within the Indian freshwaters: a mesocosm-based approach Open
Amazon sailfin catfish is relatively a recent invader to the open waters of India, and studies on ecological assessment of the species within the Indian freshwaters are lacking. In the present study, to assess the ecological impact of catf…

Transverse Fluctuations and Their Effects on the Stable Functioning of Semiconductor Devices Open
Semiconductor plasma is often found in chaotic unpredictable motion which shows some anomalous behaviors providing multiple challenges to work with the instabilities in a semiconductor device. Experimental studies have shown that these ins…
Fecal glucocorticoid metabolite levels in captive Indian leopards (Panthera pardus fusca) housed under three different enrichment regimes Open
Environmental enrichment improves the health and wellbeing of zoo animals. To test this hypothesis, we used Indian leopards ( Panthera pardus fusca ), one of the popular zoo animals, as a model organism to understand effects of active and …
Proof-of-Concept Studies Demonstrate That Food and Pheromone Stimuli Can Be Used to Attract Invasive Carp So Their Presence Can Be Readily Measured Using Environmental DNA Open
The utility of environmental DNA (eDNA) as a detection tool for fisheries management is limited by dilution and degradation, especially in areas of low fish abundance. This proof-of-concept study addressed these challenges by testing wheth…
Skeletal Deformities in Invaded Population of Amazon Sailfin Catfish Pterygoplichthys pardalis (Castelnau, 1855) in the East Kolkata Wetland, India Open
The incidence of severe vertebral deformity was reported in the specimens of the Amazon sailfin catfish Pterygoplichthys pardalis (Castelnau, 1855) for the first time in India. Fish samples were collected on bimonthly basis during June 201…
Larger versus smaller heterospecifics: shoaling behavior in orange chromides, an endemic cichlid of the Indian subcontinent Open
Larger versus smaller heterospecifics: shoaling behavior in orange chromides, an endemic cichlid of the Indian subcontinent
Effects of active and passive enrichment regimes on fecal glucocorticoid metabolite levels in captive Indian leopards (<i>Panthera pardus fusca</i>) Open
Environmental enrichment improves health and wellbeing of zoo animals. To test this hypothesis, we used Indian leopards, one of the popular zoo animals, as a model system to understand effects of active (interacting) and passive (nonintera…
A Blend of F Prostaglandins Functions as an Attractive Sex Pheromone in Silver Carp Open
A series of laboratory experiments tested the hypothesis that the Silver Carp (Hypophthalmichthys molitrix), an invasive river carp from China, employs a prostaglandin F2α-derived sex pheromone that is attractive and species-specific. Usin…
Attracting Common Carp to a bait site with food reveals strong positive relationships between fish density, feeding activity, environmental <span>DNA</span>, and sex pheromone release that could be used in invasive fish management Open
Measurement of environmental DNA ( eDNA ) is becoming a common technique to survey for rare and invasive fish due to its sensitivity and specificity. However, its utility is limited by an incomplete understanding of factors governing its s…
Elephant Conservation: Reviewing the Need and Potential Impact of Cognition-based Education Open
Conservation education programs centered on animal cognition seem to be effective in bringing humans closer to non-human species and thereby, influencing their conservation attitudes. Systematic evaluation of the impact of cognition-based …
Invasive Bighead and Silver Carps Form Different Sized Shoals that Readily Intermix Open
Two species of congeneric filter-feeding microphagous carps from Asia, the bighead and the silver carp, were recently introduced to North America and have become highly invasive. These species of carp have similar food habits but the silve…
