| Tiago Repolho and Rui Rosa's latest grant
Dr. Tiago Repolho and Dr. Rui Rosa, were recently awarded with a grant by the PADI Foundation USA. This grant will allow us to study the effects of Ocean warming and Ocean acidification on seagrasses biological, photophysiological and biochemical processes. This research study will contribute for a better understanding of the effects of climate change drivers upon seagrasses biology and physiology, under an ecological relevant perspective (i.e. species chronobiology). Project title: The effects of global climate change and environmental driven chronobiology on a pioneer seagrass species |

| RRLab is on the News - Shark nursery in Cape Verde
Following Rui Rosa's presentation at the 1st Marine Biology Congress for portuguese speaking countries - "A brigde between seas" (Faro, Portugal), our on-going study regarding the characterization of shark nurseries in Cape Verde made waves in the portuguese media. It was featured in multiple mainstream online newspapers (TSF, Observador, Diário de Notícias, Lusa, Correio da Manhã, Porto Canal and so on...) , including a sports news website (A Bola) ! Talk about public outreach... :) This study was funded by the PADI Foundation, | RRLab and Seaprairies - Biosfera interview
Seapraires represent one of the most productive ecossystems of the planet, providing a miriad of goods and services. Thus, it is essential to understand ihow will they respond to future scenarios of climate change. In this context, Dr Tiago Repolho, the leading author of a recent RRLAB study on the matter, was recently interviewed on Biosfera, hosted by RTP1 TV chanel. Click here to watch the full interview. |

| Rui Rosa's latest grant
Dr. Rui Rosa, was recently awarded with a new grant by the PADI Foundation USA. Through the direct involvement of the local population, this grant will allow us to describe and assess the first hammerhead shark nursery in the Eastern Atlantic Ocean. Hopefully, the research efforts and data collected will considerably improve the eficiency of conservation efforts directed to the emblematic scalloped hammerhead shark. Project title: Description and assessment of the first hammerhead shark nursery in the Eastern Atlantic Ocean. (Ref: 28572) |

| JEB just sent one of our PhD Students to French Polynesia!
Our PhD Student José Ricardo Paula, was recently awarded with a new grant by the Company of Biologists - Journal of Experimental Biology, which will fund the development of field work at Moorea, French Polynesia. This grant will allow us to evaluate the potential effects of elevated CO2 (Ocean Acidification) in cleaner fish (Labroides dimidiatus and Labroides bicolor) cooperative behavioural responses under a neurobiological scope and its repercussions to coral reef ecosystems. Project title: Neurobiological responses to elevated CO2 in cleaning mutualisms (Ref: JEB 170212) |
EXPLORING THE OCEANS OF TOMORROW...
Led by Rui Rosa, the RRLAB seeks to understand how future environmental changes, such as climate change and ocean acidification, affect marine biodiversity. Future changes in ocean's chemistry, temperature and oxygen levels (hypoxia) are predicted to dictate deleterious physiological responses at organism-level, and drive, at community-level, profound impacts on diversity and biogeography. We have been investigating how these climate-related variables may interfere with critical biological processes, including acid-base regulation, energy metabolism, growth potential and calcification processes in coastal marine species.
Concomitantly, our research team is also studying bathymetric and global-scale patterns of marine biodiversity and their causes. In fact, broad-scale species richness gradients are among the most prevalent patterns in the planet, but understanding the causes is one of the greatest contemporary challenges for ecologists. Marine biodiversity research lags behind that on land, with only 10% of overall biodiversity research devoted to marine biodiversity and exhibits a general neglect of developments in general ecological theory.
