Summary: Research reveals that modern grey wolves trace their origin to the Late Pleistocene Beringian population, with wolves from Far East and North America having a common ancestry before 34400 years ago. Coastal and inland North American populations diverged around 16000 years ago, consistent with the proposed ecological viability of the migration route. Historical effective population sizes of Far East and North American inland populations are larger than coastal populations, possibly due to the influence of broadscale climatic changes.

Summary: The loss of large animals due to overhunting and habitat loss potentially affects tropical tree populations and carbon cycling. However, the specific effects of defaunation on seed dispersal and predation, as well as their implications for tree population dynamics and forest carbon storage, are still unclear. Further research is necessary to understand the cascading changes in species composition and diversity caused by defaunation.

Summary: This study investigated the germination response of alpine and subalpine meadow plants to diurnally alternating temperature. Results showed that higher temperature delayed germination time and reduced germination synchrony in both subalpine and alpine meadow plants. Subalpine meadow plants were more sensitive to temperature changes. Additionally, seed mass had different effects on germination traits in alpine and subalpine meadow plants under different temperature conditions.

Summary: Aleppo pine is a valuable species used for reforestation programs in Jordan. The study aimed to assess variation in cone and seed traits within and between populations. Significant inter- and intra-population variation was observed, with more variation among populations. Natural populations showed higher variability compared to planted populations. Altitude was positively correlated with cone and seed traits, while mean annual temperature showed a negative correlation. The findings suggest the need to consider altitude in future reforestation efforts and the potential for genetic improvement and conservation of Aleppo pine in gene banks.

Summary: This study utilized a long-term plant survey to investigate the effects of management practices on weed population dynamics based on seed size. Results showed that as disturbance level increased, large-seeded weed species had higher colonization success and survival rates compared to small-seeded species. Various management practices such as tillage, herbicide application, and mowing had different effects on demographic parameters of weed populations, indicating a strong relationship between management practices and seed size in predicting weed community dynamics.

Summary: Climate change has affected the breeding parameters of a bird species, the Red-backed Shrike. A 23-year study found a 5-day shift towards delayed breeding in a central European population. The increase in rainfall was identified as the probable cause for the delayed nesting. These findings demonstrate the rarity of delayed nesting in recent years among birds.

Summary: Animal personality is described by consistent behavioural traits, measured using various methods such as observations and trapping indices. In this study with Eurasian red squirrels, measures of trappability and trap-diversity were found to be repeatable, but not correlated with exploration from OFT, suggesting they represent different aspects of personality (boldness and a different exploration tendency, respectively). Further caution is advised when using OFT behaviors to measure multiple personality traits, and additional methods such as trapping responses can provide reliable proxies for boldness and exploration tendency.

Summary: The study found that lesser black-backed gulls exhibit consistent individual strategies for non-breeding distributions, winter site fidelity, migration routes, and timing of migration, regardless of migration distance. However, there are still individual differences in behavior, and these differences are not related to migration distance. This suggests that individuals have the capacity to adjust to current conditions within their individual strategies, and occasionally even change their strategy.

Summary: Non-frugivorous waterbirds play a crucial role in dispersing weed plants over long distances, exchanging species between human-dominated and natural areas. The study demonstrates that about 92% of weed seeds are dispersed within the birds' activity area, while the remaining 8% reach other habitats, with 42% reaching moist environments suitable for weed establishment. This research emphasizes the significance of non-frugivorous birds in long-distance plant dispersal, an often overlooked mechanism in weed plant expansion studies.

Summary: Animals use the stress response to cope with environmental perturbations. In response to stress, vertebrate animals may release glucocorticoids (GCs) which can have both beneficial and detrimental effects. The study shows that native red squirrels can habituate to prolonged contact with invasive grey squirrels, reducing the potential harmful effects of chronic elevation in GCs.

Summary: The nutrient composition in the diet of brown bears has metabolic significance and is related to their foraging behavior. The study found that brown bears have a diet dominated by vertebrates and ants in spring and early summer, and berries in fall, resulting in protein-rich and carbohydrate-rich diets, respectively. Although there were differences in dietary ingredient proportions between reproductive classes, the nutrient concentrations in the diet were similar, indicating that bears are able to maintain a consistent nutrient profile by selecting different ingredients. The study also showed that the bears' diets provided sufficient glucogenic substrate for efficient metabolism throughout the year, suggesting either a driving force of metabolic efficiency in diet selection or abundant natural resources available to the bears.
