Summary: The study shows that significant changes have occurred in the key waterfowl habitats in the Klamath Basin and Sacramento Valley since 1980, with a noticeable increase in the population size of Pacific greater white-fronted geese. The body condition of geese varies nonlinearly throughout the winter and within years, with differences in adaptation to habitat conditions between males and females. Geese have adjusted historical spatial use patterns to take advantage of more favorable conditions in the Sacramento Valley, indicating their adaptability to a changing landscape between 1979 and 2010.

Summary: Research findings suggest that the population of greater white-fronted geese on the Arctic Coastal Plain in northern Alaska has been increasing steadily, but the growth rate has slowed down as the population size has increased, indicating that the geese may be approaching carrying capacity. The study revealed that goslings grew faster in coastal areas compared to inland freshwater sites, likely due to higher quality forage in coastal areas.

Summary: This study investigated the arrival timing and foraging behaviors of greater white-fronted geese in wintering areas and highlighted the potential underestimation of energetic demands and competitive nature of early migratory geese by current bioenergetics models. The findings contribute to the refinement of bioenergetics models and future waterfowl habitat planning efforts.

Summary: The study compares migration strategies between three Eurasia Greater White-fronted Geese populations and finds that they have different responses to the topographic challenges along their migration routes. BNS population faces no obvious ecological barriers and has shorter stopover duration. In contrast, EAC population faces more ecological barriers and has longer migration distance and time. WP population also faces similar challenges but with shorter migration duration.

Summary: The midcontinent population of greater white-fronted geese has shifted their winter distribution from the Gulf Coastal Plain to the Mississippi Alluvial Valley over the past five decades. This shift occurred in two stages, following the 1994-1995 season and the 2009-2010 season, and can be divided into three distinct time eras: historical era (1974-1995), transitional era (1995-2010), and current era (2010-2018). The changes in winter band recovery distribution and midwinter waterfowl survey counts support this shift.

Summary: Research on woodland caribou's dietary habits revealed a reliance on lichen-associated fungi, with yew being a primary food source in lichen-poor environments. Conservation efforts for caribou should consider the availability of food resources beyond lichen.

Summary: Climate change has a significant impact on bird habitat, migration, and reproduction. This study focused on the vulnerable species, the lesser white-fronted goose, and evaluated its suitable breeding ground distribution in Siberia using satellite tracking and climate change data. The analysis predicted a decrease in suitable breeding habitats due to future climate change. Additionally, a large portion of optimal habitats were found outside of protected areas. Obtaining species distribution data is crucial for habitat protection in remote areas.

Summary: The wintering strategy of white-fronted geese is showing extreme plasticity, with high rates of immigration to contemporary wintering regions and emigration from historical wintering areas. There is an anticipated shift in wintering distribution towards the east. Unexpectedly, greater energy expenditure in contemporary wintering regions suggests balanced energy acquisition due to increased feeding time in those regions compared to historical areas.

Summary: Phenological mismatches driven by climate change affect the fitness and population dynamics of herbivorous goose species. Water regime changes at wintering sites influence the food availability for geese, leading to variations in abundance and distribution. Both early and late water recession patterns result in limited food conditions and threaten the Lesser White-fronted Goose population.

Summary: This study evaluated the effects of mass capture of flightless geese during the summer on the survival of after-hatch-year geese. The results showed that longer individual holding times had a negative impact on survival during the first year after banding, while there was a positive relationship between survival and captured flock size. The authors suggest reducing holding times and continually refining capture methods to minimize negative effects.

Summary: Next-generation sequencing technology has allowed accurate insights into the diet of wildlife species. A study compared two protocols for faecal sample collection and DNA extraction, selecting one that performed significantly better across multiple parameters for both target species and diet DNA. This strategy can save time, effort, and cost without compromising efficiency and may be useful for studies combining target species and their gut microbiome and parasitic load.

Summary: This study compares the trophic selectivity of barnacle geese and greater white-fronted geese in their highest reproductive concentration areas, and evaluates the role of competition in their population dynamics. The findings suggest that although there are differences in the plants consumed by these species, it is not enough to avoid competition. Barnacle geese show higher selectivity in their diet, but their relatively weak competitiveness contradicts their exponential population growth. The differences in population dynamics between the two species are currently determined by anthropogenic and climatic factors outside of their nesting range.

Summary: The accuracy and reliability of DNA metabarcoding analyses rely on the quality and breadth of reference libraries supporting them, but obtaining and managing large volumes of sequence data on public repositories remains a challenge. This study introduces a pipeline for downloading, cleaning, and annotating mitochondrial DNA sequences for specific fish species, with features including support for multiple metabarcode markers, quality control, and coverage reports. This pipeline aims to facilitate the scaling up of fish metabarcoding across wide spatial gradients.

Summary: Understanding the factors that trigger and terminate insect pest outbreaks is crucial in the face of global climate change. In northernmost Europe, climate-driven range expansions of geometrid moths have resulted in severe outbreaks, but the impact of parasitoids on these dynamics is unclear. Constructing a DNA barcode reference library for parasitoids can provide valuable information on their abundance and community composition, helping to elucidate their role in moth population control.

Summary: The study found that the increasing population trend of Greater White-Fronted Geese in the Middle and Lower Yangtze Floodplain Ramsar site is mainly driven by suitable habitat availability and landscape attributes, with weak effects from climate factors. Implementing a fishing ban policy can improve habitat conditions, but grazing prohibition policy may have negative impacts on goose abundance.
