Studying how seals adapt to extreme environments could lead to benefits in human reproductive health sciencedaily.com/releases/2025 🦭 #Seals #MarineMammals #MarineLife #MarineBiology #Pinnipeds

ScienceDailyStudying how seals adapt to extreme environments could lead to benefits in human reproductive healthWild animals that have acquired adaptions to maximize their reproductive output in some of the world's most extreme conditions may provide answers to some of the most pressing problems in the field of human reproductive health. A new journal article examines how the study of seals in particular can benefit human health, and synthesizes various research on the topic. Several aspects in the life history of seals that could provide significant insight into their reproductive physiology -- as well as that of humans -- include female seals' ability to undergo lengthy fasting and lose about 30% of their body weight while nursing a pup. Seals also have an exceptional ability to hold their breath for up to two hours in some species for long dives. Additionally, seals have the ability to 'pause' pregnancy, through a process known as embryonic diapause, so they can give birth during benign environmental conditions. In seeking ways to improve human health, we should be looking to the extraordinary feats of wild animals. They have often found the most innovative solutions.

[Connor, Ardoin & Leo] Effects of anthropogenic noise on marine mammal abundances informed by mixed methods nature.com/articles/s44183-025 🦭 #Seals #MarineMammals #MarineLife #MarineBiology #Pinnipeds #OceanNoise

NatureEffects of anthropogenic noise on marine mammal abundances informed by mixed methods - npj Ocean SustainabilityThis mixed-methods study examined the decline of a Harbor Seal (Phoca vitulina) colony’s abundance in Pacific Grove, California, USA, documented by community scientists. We combined generalized additive modeling (GAM) of abundance trends from 2003 to 2023 with qualitative analysis of Local Ecological Knowledge (LEK) obtained through interviews. LEK identified various anthropogenic disturbances that may have contributed to the colony’s decline. Statistical analysis revealed that, in 2022 and 2023, Harbor Seal abundance was 29.81% lower than expected, given the availability of prey fish in their forage range. Notably, roadwork near the colony during the 2022 pupping season likely impacted reproductive success and reduced habitat suitability, potentially impacting abundance. This study underscores the demographic impacts of human disturbances on marine mammals, the effectiveness of mixed-methods and community science in ecological research, and the critical need to mitigate disturbances to protect sensitive marine mammal populations, especially during critical periods like pupping seasons.

Seallapalooza!

Another image taken with my new Sony 400-800mm G Lens. This being what appeared to be a pretty fun Seal Party going on on Bird Island off of 17th Mile Drive, CA.

Admittedly I was a bit nervous when I pre-ordered this monster as it is the largest lens investment I have personally ever made. But even with the rather brief local wildlife shoot today, and with most settings on auto, I am delighted to have this in my kit now.

First day out with my new Sony 400-800mm G Lens. It did not disappoint. One of the many impressive shots today was this Harbor Gal with a newborn Pup (8am PDT this morning according to the guide at the Hopkins Beach Rookery in Pacific Grove). If you look real close, you can still see the umbilical on the Pup.

Taken at the full 800mm. This is simply a shot I could not have been able to get before.
