Mapping technique has not been popular in holothurian monitoring procedures. We introduced the use of global positioning system to determine the local distribution pattern and estimate the individual number of Holothuria albiventer al Medana Bay, West Lombok, Indonesia.

Hernowo JB, Alikodra HS. 2018. The grouping system and local distribution pattern analysis of Javan green peafowl (Pavo muticus muticus, Linnaeus 1758) population in Baluran and Alas Purwo National Parks, East Java, Indonesia. Biodiversitas 19: 1690-1695. The Javan green peafowl population lives in a group system. The population applies a small size group system. The distribution of the birds in Java Island is randomly fragmented and isolated in several types of habitat and each has a small number of individuals in every group. Baluran and Alas Purwo National Parks, East Java, Indonesia as part of Javan green peafowl (Pavo muticus muticus, Linnaeus 1758) distributions have been selected for the study on the grouping system and the analysis of local distribution. The research was aimed at obtaining data and information on the grouping system and local distribution of Javan green peafowl population in Baluran and Alas Purwo National Park. The number of individuals and groups was counted by applying a transect method and a concentration method on every type of habitat where peafowls are present. The distribution pattern data were analyzed by using a formula (Ludwig and Reynolds 1988). The results indicate that Javan green peafowl population is living in small groups (2-4 birds). There are 5 types of Javan green peafowl groups in Baluran National Park (BNP) and Alas Purwo National Park (APNP). The dominant group is adult female group consisting 3 individual members. The leader of the group is a female bird. Adult males live in solitary. The group system among Javan green peafowl populations is a strategy of the birds. Local distribution of Javan green peafowl populations in Baluran and Alas Purwo National Parks is mostly in the form of clumped dispersion.

Abstract A new locality of regionally alien and rare Virga pilosa was recorded outside the compact range of the species in the Wielkopolski National Park, midwestern Poland. It probably appeared as a result of unintentional anthropochory. Local distribution pattern of V. pilosa in micro- and mesoscale was described and interpreted in the light of life and dispersal strategy and habitat conditions of the species. Accidental epizoochory and unintentional anthropochory could have been responsible for the mesoscale distribution pattern with population units scattered along human and animal communication routes. Close dense autochory together with the species CR life strategy with a strong competitive component were responsible for microscale distribution pattern alternating in space and time, but always mosaic, including vegetative, generative and mixed patches. The distribution pattern was also influenced by the occurrence of the required combination of the moderately light, moderately moist and nitrogen-rich habitat conditions with favourable human-induced disturbance. Some data on the form of growth, reproductive potential and dispersal mode of the species, as well as on plant-animal interactions were also included.
