New Research on Wavelet Methods for Otolith Contour Studies accepted in Reviews in Fish Biology and Fisheries
We are pleased to announce that the article titled "Choosing Wavelet Methods for Otolith Contour Studies" by Dr. Joana Vasconcelos and colleagues has been accepted for publication in the prestigious journal Reviews in Fish Biology and Fisheries. This study presents a comparative analysis of wavelet-based methods for identifying populations and phenotypes. Specifically, it contrasts the results from the shapeR package with the AFORO methodology, both widely used in fisheries science. The blue jack mackerel (Trachurus picturatus) was selected as the focal species for this research, offering valuable insights into its population structure. The findings from this study are expected to make a significant contribution to the field, providing researchers with a clearer understanding of how to select the most suitable method for otolith contour analysis. Stay tuned for the article’s release to uncover the full details and implications of this innovative research!
Research Alert!
New Research Publication: "Rising Temperatures, Falling Fisheries: Causes and Consequences of Crossing the Tipping Point in a Small-Pelagic Community"
We are thrilled to announce the publication of our latest research article, titled "Rising Temperatures, Falling Fisheries: Causes and Consequences of Crossing the Tipping Point in a Small-Pelagic Community," in the esteemed journal Reviews in Fish Biology and Fisheries. This study, published today, addresses the profound impacts of global climate change on marine species, communities, and ecosystems, with a particular focus on small pelagic fish. These species serve as valuable indicators for detecting regime shifts in fish stocks due to their swift and measurable responses to changes in oceanic conditions. Published in a journal with an impressive impact factor of 5.9, this work contributes vital knowledge to the ongoing discourse on climate change and marine biodiversity. We invite you to explore the full article (here.) to delve into the detailed analyses and insights that underpin our conclusions. Thank you for your support and happy reading! 🐟📖
Exciting News!
New article publushed in Estuarine, Coastal and Shelf Science
I'm thrilled to share that my latest research article has just been published online today in ScienceDirect! 🎉 The article is titled: "Phenotypic response of a geographically expanding species, Scomber colias: Clues in the fish otolith shape". In this study, we delve into the fascinating world of the Atlantic chub mackerel, Scomber colias, and explore how its otolith shape—those tiny, intricate ear bones—reveals crucial insights about its adaptation and expansion. Our findings offer new perspectives on the phenotypic responses of this species as it navigates changing environments. Curious to know more? Dive into the full article here: Read the Article.
