Lifetime growth in wild meerkats: incorporating life history and environmental factors into a standard growth model

TL;DR: It is found that meerkats exhibit monomolecular growth, with the best model incorporating separate growth rates before and after nutritional independence, as well as effects of season and total rainfall in the previous nine months.

Impact of climate change on alpine vegetation of mountain summits in Norway

TL;DR: In this paper, the authors quantified long-term changes in species richness, cover, composition and thermophilization (i.e., the increasing dominance of warm-adapted species) of vascular plants, lichens and bryophytes on four summits at Dovrefjell, Norway.

Composition and temporal variation in the diet of beluga whales, derived from stable isotopes

TL;DR: Investigating how belugas diet in Cumberland Sound varied between sexes, among age classes, and over time from 1982 to 2009 found a strong, decreas- ing trend in both δ 13 C and δ 15 N values over time, indicating either a temporal shift in beluga diet or an ecosystem-wide change in isotope values.

Assessment of measurement uncertainty via observation equations

Antonio Possolo, +1 more
- 07 Nov 2007 - 
TL;DR: In this article, an alternative approach is proposed, which starts from the observation equation, which relates the experimental data to the measurand: this allows a uniform treatment of the most diverse metrological problems, and, once it is used in the context of Bayesian inference, also facilitates the exploitation of any information that may pre-exist about the measurement, alongside the information that fresh experimental data provide about it.

Heritable differences in fitness-related traits among populations of the mustard hill coral, Porites astreoides.

TL;DR: Differences observed in naive juvenile corals suggest that population-level variation in fitness in response to different thermal environments has a genetic basis and could represent raw material for natural selection in times of climate change.
