“…lebih menyukai kondisi lingkungan yang kotor (Sutikno et al, 2021). opulasi tikus ini merupakan komponen kunci dari sebuah ekosistem (Stefke & Landler, 2020). Peningkatan suhu dan musim kemarau menyebabkan penurunan kelimpahan tikus (Mamba et al, 2019) Untuk mengurangi pasokan makanan tikus, beberapa standar agronomis harus dilakukan.…”

Tikus merupakan salah satu hewan yang dapat menyebabkan kerusakan pada tanaman kelapa sawit sehingga juga mempengaruhi perekonomiannya. Pada tanaman menghasilkan, hama ini dapat menyebabkan kerugian hingga 5% dari total CPO/ha/tahun dan kerusakan sebesar 80% pada tanaman belum menghasilkan. Perubahan komposisi hutan menjadi kelapa sawit akan mempengaruhi populasi dan jenis tikus. Penelitian ini dilakukan pada 7 kecamatan di Kabupaten Kuantan Singingi. Penelitian ini menggunakan metode survey. Lokasi pengamatan ditentukan berdasarkan luas areal perkebunan kelapa sawit rakyat yang terletak dalam satu hamparan dengan minimal 10 ha. Pada masing-masing lokasi penelitian dipasang sebanyak 20 perangkap tikus dengan ukuran perangkap 30 cm x 20 cm x 15 cm dengan menggunakan umpan berupa ikan asin bakar dan kelapa bakar (masing masingnya 10 perangkap) pemasangan perangkap dilakukan selama 7 hari per lokasi penelitian. Sebanyak 575 individu tikus tertangkap dan teramati pada penelitian ini dengan rata-ata penangkapan per lokasi adalah 82,14 individu tikus. Ditemukan sebanyak empat jenis tikus yaitu Rattus tiomanicus (56,34%), Rattus argentiventer (42,43%), Rattus rattus (0,70%) dan Rattus exulans (0,53%). Rasio sex tikus secara umum dilokasi penelitian didominasi oleh jenis kelamin tikus betina dengan nilai 0,97. Sedangkan preferensi umpan yang lebih dominan adalah umpan kelapa bakar yaitu tertangkap sebanyak 319 individu tikus sedangkan umpan ikan asin bakar hanya 256 individu tikus. Persentase kelapa sawit terserang pada perkebunan kelapa sawit rakyat ini adalah sebesar 37,19% sedangkan upaya pengendalian hama tikus yang dilakukan oleh kelompok tani kelapa sawit di Kuantan Singingi adalah dengan cara pemasangan umpan beracun, pemasangan perangkap dan perburuan terhadap tikus.

“…Therefore, Common Barn-owls are important regulators of populations of mammalian agricultural pests (Wood and Fee 2003;Peleg et al 2018). The diet reliably mirrors the status of small mammal communities, even indicating the presence of populations of sparse and difficult-to-find species (Milchev 2012;Torre et al 2015;Veselovský et al 2017;Horváth et al 2019;Kiamos et al 2019;Stefke and Landler 2020).…”

The diet of the Common Barn-owl in a forest- and shrub-dominated hunting area in the Strandzha Mountains, southern Bulgaria, was identified from 516 prey specimens. Shrews (52.9% by number, 26.7% by biomass) and rodents (42.1% N, 71.5% B) were prevalent. Among them, White-toothed shrews, Criocidura sp., (45.3% N, 21.4% B) was the most numerous prey genus. Mice, Apodemus sp., (15.7% N, 29% B) contributed with the largest share to the food biomass due to high predation of Striped field mice, A. agrarius, (12.2% B). The proportions of forest species in diet (Apodemus sp, Sorex sp., and dormice liridae) increased with the higher proportion of forest habitats (forests and shrublands cover more than 25% of the area) in most Barn Owl hunting territories in southern Bulgaria.

“…Three granivorous rodents, namely the striped field mouse Apodemus agrarius (Pallas, 1771), the yellow-necked mouse Apodemus flavicollis (Melchior, 1834), and the harvest mouse Micromys minutus (Pallas, 1771), all occur in a wide variety of habitats but favour areas of tall, dense vegetation [ 1 , 2 , 3 , 4 ]. These closely related species are common in Central and Eastern Europe [ 5 , 6 , 7 , 8 ]. In Lithuania, populations of the above mentioned granivores may occur syntopically in moist habitats [ 9 , 10 ] but little is known about their diet and interspecific relationships.…”

In agricultural habitats, diets and trophic positions of syntopic granivorous small mammals are not known sufficiently. Agroecosystems may be quite complex isotopically and the most complex situation concerns the nitrogen-15 isotope as δ15N values are influenced by many internal and external fluxes. We analysed the isotopic niches of striped field (Apodemus agrarius), yellow-necked (Apodemus flavicollis), and harvest (Micromys minutus) mice living sympatrically and syntopically in apple and plum orchards, raspberry and currant plantations, and nearby meadows that were used as control habitats. Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios from hair samples were used as a proxy for their diet. As the main hypothesis, we expected differences in the isotopic niches of these three species, minimising interspecific competition. All species were fully separated according to δ15N values, presuming different amounts of food of animal origin in their diet. The separation of species according to δ13C was not expressed in all habitats. The core dietary niches of these species were fully separated in the apple orchards and raspberry plantations. Intraspecific differences of the isotopic niche were not present in any of the three species: that is, resources were equally used by males and females, adults, subadults, and juveniles.
