The probability of polar bears being present was negatively related to length of the ice season (Figure 5A, Table 3A), indicating that more bears were encountered on land in years when the ice season was short.
Polar bears were forced to move on land sooner due to the shortening of the ice season

Understanding causes and consequences of climate-related shifts in ecosystem functioning, as well as the role of focal species in these processes, is currently a dominant theme in ecology.
This study highlights the significance of climate change on predator-prey interactions in the artic.

At least 11 of these species are of conservation concern, such as the critically endangered smalltooth sawfish (Pristis pectinata) and hawksbill turtle (Eretmochelys imbricata).
I wonder why they chose these two species to mention in their abstract.

anthropogenic
I had to look up that this was human activity.

Alligators are extremely cryptic, making traditional methodsfor estimation of population size ineffective.
The alligators' ability to blend seamlessly into their environments can make them difficult to observe, leading to potential underestimations or inaccuracies in data collection.

Most alligators inLouisiana were harvested by the fishing method, which wasnon‐selective in nature with respect to size of alligatorsharvested (Joanen and McNease 1987)
This approach highlights the need for more sustainable and selective harvesting practices that balance economic interests with the long-term health of the alligator population and its habitat.

Patterns of parasitism are described in terms of prevalence of infection, taxon richness, and the magnitude of multiple infections, fecal egg count and, in the case of protozoa, the intensity of infection.
All of these together provide a comprehensive picture of parasitism in a population.

Individuals seen on the ground more frequently tended to have both more ciliate and nematode infections
This would make sense since they most likely had increased exposure.

Researchers may exert subtle effects on wildlife by altering habitat. The creation of trails is common at long-term research sites (Strier 2010). The impact of these activities on animal behavior or disease ecology is unknown. Habitat alteration can affect patterns of parasitic and bacterial infections within primate populations
I never thought about how something so subtle could have such a significant effect on bacterial infections.

We determined age based on tooth wear and condition and sex for each individual
I wonder exactly how accurate this actually is. I wonder how closely you can tell age by these factors.

Home ranges are used to understand how animals use landscapes, but use of home ranges is not uniform and subsets of populations may exhibit different temporal and spatial patterns of simultaneous use
While home ranges are crucial for understanding animal behavior, there is significant variability in how different animals utilize these spaces.

we identified 67 loci that are potentially under directional selection, but only 3 were potentially associated with protein coding genes. It would be instructive to study each gene separately and rank them according to their level of fixation, paying closer attention to those genes that are nearly fixed, a potential indication of stronger selection levels.
This highlights a critical gap in understanding how selection acts on genes. Focusing on nearly fixed genes could reveal which ones are under the strongest selective pressures.

By then, reefs had already been severely disturbed by major rearrangements that happened during World War II, where several hundred ships, landing crafts, and thousands of US Naval personnel had staged out of the Atoll (Lessa 1966).
I never thought about how significantly the war affected the ocean, but now that I'm thinking about it, the war was most likely very detrimental to many habitats, not just corals.
