The yellow clam, Amarilladesma mactroides, is an abundant component of the intertidal infauna of the southwestern Atlantic Ocean and an important source of food and income for local communities. In recent years, this species has been increasingly affected by anthropogenic and environmental pressures, contributing to the decline and collapse of several populations. In this study, we characterized the reproductive cycle of A. ma...

Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim). We also modeled the environmental variables as a function of spatial and temporal variables and...

Broodstock conditioning involves maintaining adult animals in optimal environmental conditions to ensure that the largest number of breeders reach maturity. We evaluated the gonadal development and the occurrence of spawns in the yellow clam (Amarilladesma mactroides) and estimated the duration of conditioning that results in the highest maturity rate. Clams were kept buried in a 10 cm sand bed within Ø = 15 cm containers. A c...

The identification and analysis of urban roof materials using remote sensing technologies has attracted growing interest among Earth observation researchers in recent years. A georeferenced dataset has numerous applications in fields such as cadastral management, urban planning, and climate change. In this study, 907 spectral signatures were collected in June 2024 from seven roof materials and four types of urban land covers u...

This research aimed to evaluate the effect of biofloc technology on the intestinal morphometry, productive performance, and survival of juvenile Mugil cephalus. An 87-day investigation was conducted with two treatments, each with three replicates. Treatment one involved rearing juvenile M. cephalus in a biofloc system with a C/N ratio of 15:1, and treatment two involved rearing juvenile M. cephalus with a water exchange and no...

Despite the incontrovertible importance of wetland ecosystems, our understanding of the causes underlying the spatial heterogeneity of their attributes is still insufficient. Here, we assess the spatial variation of the floristics (species composition and their relative abundances) and quantitative structure (vegetation cover) of the San Pedro Mártir River riparian herbaceous wetlands (Tabasco, Mexico), and explore potential f...
