La col·lecció osteològica d’ocells de l’Institut Mediterrani d’Estudis Avançats (IMEDEA, CSIC-UIB, Esporles, Mallorca)

The avian osteological collection of the Institut Mediterrani d’Estudis Avançats (IMEDEA, CSIC-UIB, Esporles, Mallorca) In this article we present the osteological collection of extant birds curated at the Institut Mediterrani d’Estudis Avançats (IMEDEA, CSIC-UIB). This collection is part of the general vertebrate collection of the IMEDEA. It includes 2,330 specimens available via GBIF and Taxo&Map. The collection consists of complete, near complete, and partially disarticulated skeletons, all preserved dry. The specimens are from various sources: collections, donations and exchanges. Most specimens were prepared at IMEDEA. All the records we present here have been reviewed and georeferenced for publication. The collection includes 411 species from 83 families, most of them from the Western Palearctic.

Utilization of Ficus benjamina by Birds at Urban Habitat in Depok

Most of the research about the relationship of birds and figs were conducted at natural habitat. We conducted a research about this relationship at urban habitat in Depok and specifically studied utilization of Ficus benjamina by birds as feeding and nesting tree. The objective of our research was to describe the F. benjamina utilization by urban birds in Depok. Scans sampling and nest counting were used during this study. Our research shows that F. benjamina was used as feeding tree by most of birds which lives at urban habitat in Depok. Our research also shows that some birds used this fig species as nesting tree.

Keanekaragaman Jenis Burung Di Lahan Basah Way Pegadungan Desa Rajawali Kecamatan Bandar Surabaya Kabupaten Lampung Tengah

ABSTRACT Way Pegadungan wetlands is a wetland closure difference between the two riparian communities. One of the wetlands is converted into paddies fields, while the other is a natural wetland which are still overgrown with trees. To determine diversity differences in bird species between two wetlands research communities, the point count method (IPA) and line transects were used. Observations made by the stationary point count and record the birds found. Each community was taken 6 points count and observed for 3 days. Research encountered 41 species of birds included in the 17 families with a total of 796 individual in paddies fields and 46 birds species with total of 655 individuals from 17 families of individuals in natural wetlands. Natural wetlands diversity index was 3.44 with equality index of 0.90, this value is higher than the wetlands changed into paddies fields with a diversity index of 2.91, and in a stable condition with equality index of 0.78. Both wetlands communities have the same identical species approach (IS = 1) with a similarity index of 0.73. Key words: birds, diversity, wetlands, Way Pegadungan

EFFECTS OF MASH DIET AND PELLETS UPON DIGESTIVE MOTOR FUNCTIONS IN DOMESTIC HENS AND GUINEA HENS

The changes of gastric and intestinal motilities induced by food restriction and refeeding with pellets instead of an all-mash diet were compared in hens and guinea hens. Smooth muscle electrical activity was recorded in both species, which differed by their degree of domestication and food habits. Six-day fasting reduced gastric activity in both species, a phenomenon paralleled by an increase in intestinal motility and the disappearance of the diurnal cycles of gastro-intestinal activity. Refeeding increased gastric activity and reduced the intestinal activity in hens. By contrast with hens, pellets failed to induce major changes in the guinea hens, despite an increased frequency of gastric spike bursts and inhibition of the orad propagation of the intestinal spike bursts. The results suggest that hens, despite a lower responsiveness to environmental changes, are more sensitive than guinea hens to changes in diet.
