Long live the seagrass! The relationship between human disturbance and genetic diversity
The Mediterranean seagrass plays very important ecological functions but human disturbances are thought to be one of the main causes for its population decline. In this study, Jahnke et al (2015) try to understand how genetic diversity correlates with human disturbances and the results are surprising. Catarina SilvaHi! I am a PhD candidate at Victoria […]
Like father, like son? Is survival under ocean acidification heritable?
Can marine life adapt to ocean acidification? Well, first we need to understand if these favourable characteristics (survival under elevated CO2 conditions) are genetically determined and can be passed on to the offspring! Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the […]
Same species, different genes: temperature tolerance and body size in the genes of the Chinook salmon
To understand how species may cope with climate change we must look into their genes. Do individuals have different levels of tolerance to high temperature? What can genes tell us about it? Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment […]
Supermom of the depths: octopus guards its eggs for the longest period ever observed
Scientists found an octopus that guards its eggs for the longest period ever recorded. The super mother was filmed for 53 months and has produced the largest and most developed hatchlings known to date. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how […]
Are whale sharks in trouble?
A recent study at the global scale suggests that there are two distinct populations of whale shark (Indo-Pacific and Atlantic Ocean). Authors show the evidence that populations of sharks aggregating at Ningaloo Reef in Western Australia have been declining in genetic diversity from 2007 to 2012. Catarina SilvaHi! I am a PhD candidate at Victoria […]
Coral larvae will stay at their birth reef in warmer seas
New research suggests that global warming is leaving large coral reef systems less interconnected, which can affect their ability to recover after disturbance and potentially deplete local populations. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment influences genetics. Check out […]
Hotspots of unwanted catches: the global issue of bycatch
Incidental catches of nontarget species, also called “bycatch” have important ecological, social and economic impacts. A new study reveals the global distribution and intensity of bycatch of air-breathing megafauna (sea turtles, marine mammals and seabirds) and gaps in data availability. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the […]
The far-reaching benefits of marine reserves
It can actually work! A recent multidisciplinary study combining genetics and modeling conducted in the marine protected area of Torre Guaceto, Italy shows how effective marine reserves can be. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment influences genetics. Check […]
Not so alike after all: European hake populations might be locally adapted
Recent evidence that European hake populations might be adapted to local conditions (e.g. temperature and salinity at the surface) suggests the need to review current management strategies of their stocks. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment influences genetics. […]
Plenty of fish in the sea? Appearances can be deceiving.
Overfishing reduces the ability to adapt in the face of change, even in highly abundant marine fishes. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment influences genetics. Check out my website for more information! www.catarinasilva.net
