Resumen
In this study, a novel type of swarm intelligence algorithm referred as the anas platyrhynchos optimizer is proposed by simulating the cluster action of the anas platyrhynchos. Starting from the core of swarm intelligence algorithm, on the premise of the use of few parameters and ease in implementation, the mathematical model and algorithm flow of the anas platyrhynchos optimizer are given, and the balance between global search and local development in the algorithm is ensured. The algorithm was applied to a benchmark function and a cooperative path planning solution for multi-UAVs as a means

Likelihood-ratio tests indicated that significant amounts of heterogeneity existed in the data sets analyzed.

Coronaviruses (CoVs) are part of the Coronaviridae family, and the genera Gamma (γ) and Delta (δ) are found mostly in birds. Migratory birds have an enormous potential for dispersing pathogenic microorganisms. Ducks (order Anseriformes) can host CoVs from birds, with pathogenic expression and high economic impact. This study aimed to identify and characterize the diversity of CoVs in migratory ducks from Portugal.

Data were subdivided by age, sex, and sampling period. In support of the hypothesis, in 11 of 12 comparisons, hunter-shot ducks weighed less than ducks collected at the roost and those differences were significant for five of the seven largest samples.

Resumen
The breeding bird assemblage of the Rače fishpond complex in north-eastern Slovenia is described. There are three ponds (4.5 ha to 20 ha) which are managed for semi-intensive fish-farming. During 13 years (1986—1998), I estimated the number of breeding bird pairs on the bases of found nests and/or observed females with fledglings. Six species of non-Passeriformes, i.e. Tachybaptus ruficollis, Podiceps cristatus, Anas platyrhynchos, Aythya fuligula, Fulica atra and Gallinula chloropus, nested regularly. The total number of breeding pairs (excluding “possible“ breeders) varied between 12 in 1994
