The northeast area of the Bogotá Savannah (Cundinamarca, Colombia) is a region where biodiversity requires research because of few records in the current literature. We present a list of birds from the northeast area of the Bogotá Savannah. A systematic sample was conducted in the Ecoparque Sabana Nature Reserve (Tocancipá) to record the frequency of occurrence of bird species, while opportunistic observations were made at Parque Jaime Duque Nature Reserve (Tocancipá) and Aguablanca wetland (Sesquilé). A total of 820 h of sampling was done between February 2016 and June 2019. We provide a list with 128 species belonging to 37 families. Of these species, eight are newly recorded from the Bogotá Savannah; one species is considered Endangered and three are Near Threatened according to the Red List of the International Union for Conservation of Nature. The species richness found in our study supports the importance of protected areas in the northeast area of the Bogotá Savannah. Protected areas here help conserve the biodiversity of birds of the Andean region.

Abstract Farmland landscapes are recognized as important ecosystems, not only for their rich biodiversity but equally so for the human beings who live and work in these places. However, biodiversity varies among sites (spatial change) and among seasons (temporal change). In this work, we tested the hypothesis that bird diversity hotspots distribution for breeding is congruent with bird diversity hotspots for wintering season, focusing also the representation of protected areas for the conservation of local hotspots. We proposed a framework based on the use of species richness, functional diversity, and evolutionary distinctiveness to characterize avian communities. Although our findings show that the spatial distribution of local bird hotspots differed slightly between seasons, the protected areas’ representation was similar in both seasons. Protected areas covered 65% of the most important zones for breeding and 71% for the wintering season in the farmland studied. Functional diversity showed similar patterns as did bird species richness, but this measure can be most effective for highlighting differences on bird community composition. Evolutionary distinctiveness was less congruent with species richness and functional diversity, among seasons. Our findings suggest that inter-seasonal spatial congruence of local hotspots can be considered as suitable areas upon which to concentrate greater conservation efforts. However, even considering the relative congruence of avian diversity metrics at a local spatial scale, simultaneous analysis of protected areas while inter-seasonally considering hotspots, can provide a more complete representation of ecosystems for assessing the conservation status and designating priority areas.

AbstractThe conservation of wide-ranging, territorial carnivores presents many challenges, not least the inadequacy of many protected areas in providing sufficient space to allow such species to maintain viable populations. As a result populations occurring outside protected areas may be of considerable importance for the conservation of some species, although the significance of these areas is poorly understood. Brown hyaenas Parahyaena brunnea are categorized as Near Threatened on the IUCN Red List and recent research suggests the species may be particularly vulnerable to habitat loss and the conversion of land to agriculture. Here we report on the population density and abundance of brown hyaenas in an area of commercial farmland in western Botswana. Mean brown hyaena density estimated from camera-trap surveys was 2.3 per 100 km2 and from spoor surveys 2.88 per 100 km2, which are comparable to estimates reported for protected areas. Estimated densities were higher on farms used for livestock production than on those used for game farming, suggesting that the species can tolerate land-use change where reliable alternative food resources exist. Our results indicate that populations of brown hyaenas in non-protected areas comprise a significant proportion of the global population and that such areas may be of critical importance for their conservation.

A rapid bird survey was done in a small conservation area of industrial timber concession of PT BMH (Bumi Mekar Hijau), namely KPPN (Kawasan Pelestarian Plasma Nutfah), South Sumatra Province. The area has 448 ha, dominated by degraded secondary swamp forest surrounded by Acacia plantation. Three survey methods were applied to assess bird diversity in this area: transect line, mist-netting and audio-visual station recording. A total of 36 species was recorded during survey. Among three methods applied, transect line is the most effective method to detect more bird species (29 species), followed by audio-visual station recording (26 species) and mist-netting (three species). There are eight species which protected by Indonesian law and two birds are listed as Near Threatened (NT) by International Union for Conservation of Nature or IUCN. Although number of species birds recorded are not significance, but this area still support habitat for various birds diversity, and the forest remaining should be well-managed to support its conservation goals.

In Taiwan, conserved areas represent more than 20% of the current jurisdiction, which is about twice that of the proportion of protected land worldwide. In this study, we explored the spatial distribution of bird assemblages in Taiwan. By analysing functional and phylogenetic diversity relative to elevational gradient, we assessed the network of bird protected areas. Hotspots of species richness were located at the coastal areas of northern and western Taiwan, although hotspots for protected bird species were located in the mountain areas. We found that phylogenetically close birds have similar trait values, and the protected species were evenly distributed in the functional and phylogenetic trees. The assemblages in higher-elevation areas were more phylogenetically clumped than those in lower-elevation areas, indicating that, in addition to elevational gradient, phylogenetic constraint may be a crucial factor that influences bird distribution in Taiwan. However, the current bird protected areas in Taiwan may overly depend on species richness and overlook the importance of the overall phylogenetic diversity.

Vu Quang Nature Reserve, Vietnam, was brought to the attention of the world scientific community following the discovery of two previously undescribed large mammal species in the early 1990s. In light of the identification of other sites of high biodiversity value in the Annamite mountains of Vietnam and Laos, the relative importance for biodiversity conservation of Vu Quang needs to be reassessed. In this paper we evaluate the importance of the site for bird conservation, in relation to 13 other protected areas in the Annamese Lowlands Endemic Bird Area (EBA) and present species lists for all 14 sites. Whilst Vu Quang supports one of the highest numbers of recorded bird species of all 14 protected areas, a complementarity analysis revealed that Vu Quang does not fall within the critical subset of sites necessary to conserve 95% of the avifaunal diversity of the EBA. The site should not, therefore, be considered a regional bird conservation priority. Furthermore, of the nine restricted-range species known from the Annamese Lowlands EBA, only three are known from Vu Quang, which is not, therefore, a priority site for the conservation of endemic bird species. We also evaluate the conservation status of the avifauna of Vu Quang, and propose potential conservation measures to enhance its importance for bird conservation.

Abstract The Kedah Forest in Sumatra is one of the forests allocated for tourism and research purposes for the local or foreign communities. The Kedah Forest contains a wealth of biological natural resources, flora and fauna, including wood species with a high economic value (commercial). However, data on the diversity of commercial timber plant species in the area have not been recorded and documented, both in terms of tree species and their conservation status. This research aimed to identify commercial timber plant species and determine the population and conservation status of these species in the Kedah Forest. This study was carried out between October and December 2019. We assessed the species richness and the IUCN status of commercial timber species and assessed its conservation status in accordance with IUCN criteria. The result showed that Kedah Forest has 16 species of commercial timber plants from 11 families, of which six species of commercial timber plants have not been registered as commercial timber according to the Decree of the Minister of Forestry Number: 163/Kpts-II/2003 dated 26 May 2003. Four species of wood plants commercial forest in Kedah are listed on the IUCN Red List under the Near Threatened, Low Risk, and Data Less categories.

In terms of conservation, Argentinian odonates have not been assessed using a quantitative approach. One way to achieve this is by modelling their distribution to gather the extent of occurrence. Thus, we modelled the current and future (projected year, 2050) potential distribution of 44 odonate species that occur in Argentina as well as in neighboring countries. Our models of current times indicate a fairly wide distribution for most species but one exception is relevant for conservation purposes: Lestes dichrostigma has less than 30,000 km2 and falls in the ‘Near Threatened’ category according to the IUCN Red List. Another seven species have less than or close to 100,000 km2: Elasmothemis cannacrioides, Erythemis credula, E. paraguayensis, Heteragrion angustipenne, H. inca, Lestes forficula, and Mecistogaster linearis. Future distribution estimates suggest that: a) 12 species will lose or gain around 10%, four species will increase their distribution beyond 10% (up to 2,346%), and 28 species will lose more than 10% (up to 99%). Although current protected areas embrace most odonate species in Argentina, it is still premature to conclude whether this situation will remain in the future given the physiological tolerance and dispersal abilities of the study species among other drivers of distribution.

Abstract To study the seasonal changes in avian communities, we collected data in an extensively used farmland in Western Poland during 2006-2013. Generalized additive mixed models were used in order to study the effects of seasonality and protected areas on the overall bird species richness. A similarity percentage analysis was also conducted in order to identify the species that contribute most strongly to dissimilarity among each bird according to the phenological season. Furthermore, the differences in bird communities were investigated applying the decomposition of the species richness in season, trend, and remainder components. Each season showed significant differences in bird species richness (seasonality effect). The effect of the protected areas was slightly positive on the overall species richness for all seasons. However, an overall negative trend was detected for the entire period of eight years. The bird community composition was different among seasons, showing differences in terms of dominant species. Greater differences were found between breeding and wintering seasons, in particular, the spatial pattern of sites with higher bird richness (hotspots) were different between breeding and wintering seasons. Our findings showed a negative trend in bird species richness verified in the Polish farmlands from 2006. This result mirrors the same negative trend already highlighted for Western Europe. The role of protected areas, even if slightly positive, was not enough to mitigate this decline process. Therefore, to effectively protect farmland birds, it is necessary to also consider inter-seasons variation, and for this, we suggest the use of medium-term temporal studies on bird communities’ trends.
