Summary: In the wild, coordinated group behaviour is important for maintaining spatial coherence and individual fitness. However, it is unclear whether synchronizing behaviours is necessary in captivity with minimal ecological pressures. This study investigated the behaviour synchrony of two mixed-species groups (capuchins and squirrel monkeys) at a zoo in the UK. The results showed higher intraspecies synchrony but low interspecies synchrony, highlighting differences in behavioural structure between single- and mixed-species groups.

Summary: This study describes a lethal case of toxoplasmosis in a black-capped squirrel monkey in a zoo in Portugal. The monkey showed acute injuries in the liver and brain, and cyst-like structures suggestive of Sarcocystidae parasites were observed. Genetic analysis confirmed a systemic T. gondii infection linked to a non-clonal type II strain, which is consistent with the majority of T. gondii strains circulating in Europe.

Summary: This study mapped RADseq data from P. maximus and P. jacobaeus to a chromosome-level reference genome, revealing a heterogeneous landscape of genomic differentiation. Highly divergent genomic regions were found on 14 chromosomes, while five showed little differentiation. Population and comparative genomics analyses suggested an initial period of isolation followed by gene flow during secondary contact. Functional annotations indicated enrichment of immune-related processes and mRNA modification in highly differentiated regions. This study provides new insights into the speciation genomics of P. maximus and P. jacobaeus.

Summary: The Earth's surface exhibits heterogeneous characteristics at different scales, which result in scale-dependent and nonlinear atmospheric responses. Airborne measurements using wavelet analysis can detect larger scale transport of energy and other scalars, providing valuable insights into surface-atmosphere interactions and multi-scale integration of weather and climate models.

Summary: Land use in Mexico has undergone significant changes recently, with deforested areas being converted into agricultural land. This study evaluated the taxonomic and functional diversity of amphibians in a heterogeneous landscape in west-central Mexico. Results showed that different land cover/use types had varying effects on amphibian diversity.

Summary: Low-cost and high-performance execution of computing-intensive applications rely on large-scale heterogeneous computing platforms, but this raises the issue of electrical energy consumption. The Green mechanism proposed in this paper aims to reduce energy consumption caused by task duplication and has been shown to significantly reduce energy consumption in various duplication-based list-scheduling algorithms.

Summary: The study indicates that shorebirds breeding in urban areas rely on heterogeneous landscapes, such as sandy beaches and rocky shores, for successful breeding. They forage in local habitats surrounding urban beaches and are connected to nearby protected areas, suggesting that distinct and protected habitat patches can provide complementary resources for breeding successfully.

Summary: The availability of suitable habitat influences the distribution and abundance of Arctic fauna, with Arctic ground squirrels and microtine burrows abundance positively correlated with terrain ruggedness. Microtine burrows are more abundant inland and in areas with freshwater, while Arctic ground squirrels are found more often at low elevations without freshwater. The study emphasizes the habitat associations of ecologically significant small mammals in an underrepresented Arctic study area.

Summary: The study found that considering spatial nonstationarity in the Gulf of Maine can lead to improved distribution estimates for the American lobster. The finest-scale model performed best, with larger-scale models tending to overestimate lobster abundances in the western portion of the Gulf, underestimate in the western portion of the central Gulf, and overestimate in the eastern portion of the central Gulf.

Summary: This study aimed to investigate the ecological impact of landscape on three major coffee pests and found that landscape indicators had a strong correlation with pest abundance within a 300-meter radius, while the relationship between pest abundance and landscape metrics weakened beyond this range.

Summary: Soil aggregate stability is a critical indicator for soil structure and potential degradation in arid and semi-arid regions, particularly in understanding gully erosion. This study aimed to analyze soil aggregate stability at different positions along gully walls and explore the relationships between stability and local and landscape conditions. The study found that the highest soil aggregate stability was observed at the headscarps, while the lowest stability was found at the gully bottoms. Macroaggregate stability was related to terrain attributes, ground cover, and gully dimensions, while microaggregate stability was associated with ground cover, terrain attributes, gully dimensions, and proximity to roads and farm dams. This knowledge is valuable for understanding gully erosion and developing restoration strategies in semi-arid regions.

Summary: The current understanding of the link between land management practices and GHG emissions is limited in the sub-Sahara region, specifically in the small-scale farm sector. This study aimed to characterize land-use and determine the factors influencing land-use change in Tharaka-Nithi County, Kenya. The findings suggest that farmer socio-demographic characteristics play a role in land-use change, which is directly linked to soil GHG emissions.
