4). Isotopic signatures from multiple nitrogen sources on the island (i.e., diatoms, organic matter seawater, algae, and bird faeces showed that only the faecal samples all had nitrogen isotopic signatures above 10 ∂15N indicating that plants have incorporated organic nitrogen from guano (Fig....
The bird community was dominated in abundance (no. individuals) by Antarctic Petrels, Thalassoica antarctica , and in biomass by penguins. The mammal community was dominted in abundance by Crabeater Seals, Lobo-don carcinophagus , and in biomass by Crabeater Seals and Minke Whales, Balaenoptera ...
N enrichment was also strongly correlated with cormorant nest density but not with total bird abundance, supporting the idea that it is runoff on a small scale which determines enrichment. Enrichment factors in marine and aquatic systems are approximately 1–2% for herbivores, 2.5% f...

In addition, many bird species break open mollusks, nuts, or bones on stone anvils by dropping the food from the air2. We predict that these activities produce enduring use-wear on the anvils and accumulations of debris that can be studied to learn about behavioral evolution in a given ...

Other respondents noticed grading issues, unavailability of drying equipment, a higher number of days required for sun drying due to changing weather conditions, bird damage, and quality deterioration (Table 5). Most of the collectors (97%) mentioned that it took more than 10 days for proper ...
