Of the three subspecies of Critically Endangered Bornean orangutans, Pongo pygmaeus has smallest population size. One its most important habitats is tropical forest within and around Danau Sentarum National Park (DSNP). Research in late 1990s estimated that ca. 1025 orangutans inhabited DSNP, while 1717 beyond DSNP's boundaries. However, concerns were later raised incorrectly nest decay rates (...

We studied the species diversity and abundance of small terrestrial mammals in spring autumn period 2016-2019 four groups habitats protected area “Sarykum barkhans” Dagestan Nature Reserve: barkhan, floodplain forest, ailant plantations, territory cordon. During study period, 10 were recorded – E. roumanicus, C. suaveolens, leucodon, M. musculus, macedonicus, A. fulvipectus, migratorius, social...

The study investigates what an intermediate success rate means in bonobos, chimpanzees, and orangutans. Apes participated in liquid conservation experiments where they had to track the larger of two different quantities of juice after various kinds of transformations [Suda, C., & Call, J. (2004). Piagetian liquid conservation in the great apes (Pan paniscus, Pan troglodytes, and Pongo pygmaeus)...

Orangutan (Pongo pygmaeus) MHC-C appears less evolved than human HLA-C: Popy-C is not fixed and its alleles encode only one (C1) of the two motifs for killer cell Ig-like receptor (KIR) ligands. To assess the structure and complexity of the orangutan KIR locus, the complete nucleotide sequence of an orangutan KIR haplotype was determined. The PopyKIR locus is flanked by LILR and FCAR and consis...

Following the publication of this article, the editors were alerted to concerns over the accuracy and clarity of information reported regarding the source of the samples included in the study. The editors were contacted by representatives of the Borneo Orangutan Society who indicated that the samples included in this study were collected by the society for surveillance purposes as per the requi...

Agrilozodes bellamyi sp. nov. from the Caatinga Biome (type locality: Juazeirinho, Paraíba, Brazil) is described and illustrated. It differs from the other five known species mainly by the moderate longitudinal elevation between the eyes, posterolateral angles of pronotum acute and oblique, mesoepisternum excavated, elytral color pattern and elevation of interestriae 2 and 4. The distribution o...

The rare findings of specimens in larval or post-larval stages (6 phyllosomas and 7 nistos/early juveniles) belonging to the family Scyllaridae are reported for the waters around Sicily. Some were stranded on different winter occasions near the Strait of Messina (north–eastern Sicily), while others were collected during experimental trawl surveys carried out in the Sicilian Channel, at depths u...

Conservation biological control involves manipulation of the environment to enhance effectiveness natural enemies in controlling crop pests. In this study, we combined historical data, sticky trap sampling tomato greenhouses and beat adjacent vegetation identify which greenhouse characteristics, habitat management practices landscape features favour an early colonisation by key mirid predator M...

Ecological studies of orangutans have almost exclusively focused on populations living in primary or selectively logged rainforest. The response of orangutans to severe habitat degradation remains therefore poorly understood. Most experts assume that viable populations cannot survive outside undisturbed or slightly disturbed forests. This is a concern because nearly 75% of all orangutans live o...
