Summary: Chinese chestnut is one of the earliest domesticated fruit trees in China, with high-quality nuts and high resistance. This study analyzed the genetic diversity and structure of Chinese chestnut populations from different regions in China based on single nucleotide polymorphism data. The results showed a relatively high genetic diversity level in the populations, with the lowest diversity in the population north of the Yellow River. The Chinese chestnut samples could be divided into northern and southern populations, separated by the Yellow River, but some samples showed genetic closeness between the two populations. Outliers were found in samples from Shandong Province and Beijing City, possibly due to their special geographical, political, and economic significance.

Summary: Under low-input production conditions, local cattle species like the Altay white-headed cattle show remarkable adaptability to various environments. However, the selection and breeding of the native Altay white-headed cattle have been neglected, and unplanned hybridization with foreign cattle breeds has occurred. As a result, the population of pure Altay white-headed cattle has been decreasing, posing a risk of extinction. This study examines the genetic diversity and population structure of the Altay white-headed cattle using SNP genotyping data. The results indicate low genetic diversity and differentiation within the population. The findings provide valuable genetic information for the conservation and breeding research of the Altay white-headed cattle.

Summary: In coastal sand dunes, sand burial poses a common stress to plant performance. Clonal plants, like Carpobrotus edulis, exhibit reduced survival and growth in apical ramets when subjected to sand burial, while basal ramets show a compensatory response. This study demonstrates the importance of considering modular plasticity in understanding plant responses to sand burial stress.

Summary: The application of glyphosate to the invasive clonal plant Carpobrotus edulis not only negatively affects its own growth and photochemical efficiency, but also reduces the growth of untreated basal ramets connected to the treated apical ramets. Localized glyphosate application can effectively reduce the amount of herbicide used and minimize its negative impact on ecosystems.

Summary: This study investigated the efficacy of anthelmintics on sheep farms in Sweden. The results showed that the efficacy of benzimidazoles and ivermectin was lower than expected, and resistance was common. Levamisole and moxidectin showed good efficacy, but the timing of post-sampling may have underestimated the severity of the situation. Additionally, parasite DNA was detected even on farms declared as susceptible. A nationwide randomized study is needed to provide an update on the extent of anthelmintic resistance and identify risk factors.

Summary: The clouded apollo butterfly in Sweden is currently endangered and only found in three geographically separated populations. Conservation efforts include habitat restoration and captive breeding. By using whole-genome resequencing and population genomic approaches, we found that the different populations in Sweden have similar but comparatively low levels of genetic diversity, with significant genetic differentiation between the northernmost and southern populations. We also discovered population sub-structure in one of the populations. These findings provide insights into the genetic consequences of population declines and fragmentation, and important information for the conservation of clouded apollo butterflies in Sweden.

Summary: Choosing the most appropriate sampling method is crucial for estimating population size. This study compared two commonly used sampling methods for the red fox and found that camera trapping provided a slightly higher minimum number of individuals compared to DNA faecal genotyping. Abundance estimates from camera trapping were positively correlated with the number of individuals detected, while there was a non-significant negative relationship between DNA faecal genotyping and abundance estimates.

Summary: This study investigated the effects of mixed gastrointestinal nematode (GIN) infections on the growth and post-weaning activity patterns of ram lambs. The lambs and ewes were grazed in pastures naturally contaminated with GIN, and were divided into low parasite exposure (LP) and high parasite exposure (HP) groups. The results showed that delayed weaning age reduced the adverse effects of GIN infection on body weight gain, while an earlier weaning age reduced the risk of Haemonchus contortus infection. Automated behavior recordings were also demonstrated to be a potential diagnostic tool for nematode infections in sheep.

Summary: Poultry roundworms have re-emerged in European countries due to noncaged housing, impacting bird welfare and productivity. The Swedish Egg Association initiated a control program in 2009, but its data have not been fully explored, and understanding of producer perception is inadequate. This study addresses these issues through analyzing program data and conducting an online survey. The findings highlight the need for strategic sampling, appropriate diagnostic tools, and education on anthelmintics use and resistance development.

Summary: Gastrointestinal nematode infections pose a significant threat to the health and well-being of calves in pasture-based rearing systems. The serum pepsinogen assay, although an established tool, is not widely implemented due to its high cost and lack of standardization. This study evaluates the O. ostertagi-Ab ELISA as a cost-effective and robust alternative diagnostic method for first-season grazing calves and suggests that it can replace the serum pepsinogen assay for monitoring purposes at the end of the grazing season.
