Brood Parasitism

Brood parasitism is a parenting strategy in which birds do not brood their own eggs or tend to their own offspring once those eggs hatch. The eggs are deposited into the nests of other females of a different species. Shutterstock Brood Parasitism Success Strategies Unfortunately there isn’t really a “bright side” for host moms. Parasite chicks often employ strategies that render them more successful than the host mom’s own chicks. They may push host chicks
food pyramid
Do Humans Really Need A Food Pyramid? Humans are introduced to the food pyramid at a very early age. It tells us the approximate percentage of fruits, vegetables, dairy, grains, and meat we should eat. Now, the food pyramid has been replaced by the food plate. Are we so far gone as biological entities that we need professional intervention to remind us to eat a balanced diet? A general survey of the food-related illnesses that

Parasitic infections are an unfortunate part of life for most animals, humans included. Without the (unnaturally sterile) human standards of hygiene, our primate cousins contract parasites much more commonly. Humans treat parasitic infections with vaccinations or medications. Treating roundworm, hookworm, pinworm, and tapeworm involves differential toxicity. The drugs we take are toxic to our bodies, but more toxic to the bodies of the parasites.

The past couple weeks I have been sharing some wild sex
coral broadcast spawning
Broadcast spawning is a form of sexual reproduction used by many aquatic invertebrate animals. Billions of gametes (the combination of sperm and egg) are spewed into the surrounding environment of the ocean. Shutterstock Most of these animals are either sessile or they move very slowly.

Dr Carin Bondar Wild Moms book event
On a spectacular sunny May afternoon, we held a private luncheon at the Aquarium of the Pacific in Long Beach, California. The gathering was in celebration of my new book and animated series –both called Wild Moms, and it was generously put on by both by publisher Pegasus Books and my production company Seeker. I really wanted a low-key, fun event with delicious food and tons of kid-friendly activities, and this is exactly what we
Expedition video series
I travel a lot for all of my amazing adventures in Biology – and I’m often taking my phone out to capture a fun little expedition video and some photos along the way. I decided to make a series of short videos showing you some of my ‘behind the scenes’ shots that don’t necessarily make the big TV production or media coverage. This is Dr. Carin in her happy place – enjoy! « Prev1 /
