In Tasmania, a considerable proportion of the forested landscape is available for land clearance and production forestry, which has and will continue to result in a decline in hollow availability unless managed appropriately. All hollow-using species are listed as having priority status under the Tasmanian Regional Forest Agreement. To ensure the habitat for hollow-using fauna is managed effectively, we first have to understand the requirements of the species involved. This paper is a review of the distribution, hollow requirements and conservation status of the five species of arboreal marsupials, eight species of bats and 29 bird species that use hollows in Tasmania. The number of species that use hollows is lower than in many other areas of Australia, but these species represent a large proportion of the vertebrate fauna of Tasmania. Three of these species and nine subspecies are endemic to Tasmania and seven are exotic. Four bird species are listed as Threatened at the state and/or national level. Twenty-five of Tasmania’s hollow-using species are capable of using small hollows, 14 can use medium-sized hollows and three bird species are limited to using large hollows. Current records indicate that the highest diversity of hollow-using species is associated with dry forest areas.

Bird Richness

Bird species richness is an important measure for monitoring biodiversity changes. We analysed avifauna richness and composition in a 472 ha protected cerrado fragment and surroundings at Fazenda Canchim (RL-CPPSE), São Carlos, in the State of São Paulo (SP). We carried out 95.1 hours of observation (22 visits) at irregular intervals from May 2004 to December 2006. Qualitative surveys were done walking through tracks inside the fragment and on the roads at its edge. We recorded 160 species, six of which were endemic to Cerrado domain, 22 migratory, seven threatened within the State of São Paulo, and two globally threatened. We found 28 species in the cerradão, 110 in the cerrado sensu stricto, 13 in the gallery forest, 26 in the reservoir border, 26 in pasturelands and sugar cane monoculture and 55 in an anthropic area. Most of the species had low frequency of occurrence in all vegetation forms. Insectivores were the major trophic category (46.9%), which is typical in tropical regions, and it is also related to resource availability. Omnivores followed with 19.4%, granivores with 8.8% and frugivores with 7.5%. We conclude that, despite its size and conservation status, our study area has a remarkable bird community and must be considered as a priority conservation area to preserve bird species in Sao Paulo State.

The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosys tems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for the first time, a survey of the bird species and their conservation status for the different habitats present on the island. We recorded 269 bird species of 54 families (25 species were seabirds). More than 50% (140) of the total number of species were residents or probable residents, 20% (58) were visitors and a relatively high number of species (61, 23%) had indeterminate residential status. Nearly 15% (35 species) of the 244 landbird species observed were endemic to the Atlantic Forest. Habitat specificity was recorded for 40% (97 species). We recorded one Endangered (Solitary Tinamou Tinamus solitarius), one Vulnerable (White-necked Hawk Leucopternis lacernulata), and three Near-threatened species (Azure Jay Cyanocorax caeruleus, Azure-shouldered Tanager Thraupis cyanoptera, Black-backed Tanager Tangara peruviana). We also recorded six locally threatened species that we predict will become extinct in the near future. The future for the birds of the island is uncertain, especially for habitat specialists, due to habitat loss for resort developments, and a lack of concern by the government and local people.

Birds are the best-known vertebrate group, although many localities in the world are considered to be knowledge gaps. This is the case of many little-known environments in the Amazon biome, the world’s largest tropical forest. Here, we present a survey of birds in the upper Purus basin, comprising the municipalities of Manoel Urbano and Feijó in the Brazilian state of Acre, and Boca do Acre and Pauini in the state of Amazonas. In this region, poorly-studied habitats, such as open rainforest dominated by palms or bamboo, still predominate. We recorded 452 bird species during 45 field trips between May and July in 2016, and June to August in 2017. Twenty-four of these species are associated with bamboo habitat, 28 are endemic to the southwestern Amazon basin, and seven are threatened with extinction. This high diversity is typical of the western Amazon basin, one of the richest regions in the world in the number of species, due to the heterogeneity of the local environments. The data presented here highlight the importance of the region for the conservation of birds, including species typical of the western Amazon, some of which are still poorly-known.

We describe Croton calcareus Riina & Mateo-Ram. sp. nov., a new species in Croton section Cyclostigma (dragon’s blood trees) from the state of Chiapas (Mexico). This species is a small tree growing in dry forest on calcareous substrates. Both morphological and molecular data support C. calcareus sp. nov. as a new species closely related to C. redolens, another dry forest taxon from northern Venezuela. We provide illustrations, a distribution map and suggestions for species conservation status. The new species along with Croton draco are the only known representatives of C. section Cyclostigma occurring in Mexico.

Detailed distribution pattern of colubrid snakes in Serbia is still inadequately described, despite the long historical study. In this paper, we provide accurate distribution of seven species, with previously published and newly accumulated faunistic records compiled. Comparative analysis of faunas among all Balkan countries showed that Serbian colubrid fauna is among the most distinct (together with faunas of Slovenia and Romania), due to small number of species. Zoogeographic analysis showed high chorotype diversity of Serbian colubrids: seven species belong to six chorotypes. South-eastern Serbia (Pčinja River valley) is characterized by the presence of all colubrid species inhabiting our country, and deserves the highest conservation status at the national level. This study should provide the basis for further, more comprehensive faunistic research, as the data on distribution of colubrid species in our country are far from complete, with large distribution “gaps”, especially in northern and central parts of Serbia.

Private Protected Areas

Private protected areas have recently attained more importance at a worldwide level as regards nature conservation. Particularly, the specific region of Western Ecuador receives hardly any protection from the State, and private reserves could, therefore, be a suitable tool to ensure the preservation of its forests and their associated wildlife biodiversity. In this work, we compare the bird species richness between private reserves and public protected areas (managed by the State) located in this region. We also show a checklist of bird species found in the Buenaventura Reserve, a private reserve located in south-western Ecuador. Our comparison shows that smaller private reserves may harbour a similar number of bird species than larger protected areas managed by the state, and they have a higher number of bird species per area. In particular, a total of 233 different bird species were registered in Buenaventura, which were distributed in 16 orders and 42 families. Three species were classified as endangered at an international level: El Oro Parakeet (Pyrrhura orcesi), El Oro Tapaculo (Scytalopus robbinsi), and the Grey-backed Hawk (Pseudastur occidentalis), and another three at a national level: the Long-wattled Umbrellabird (Cephalopterus penduliger), the Slaty-winged Foliage-gleaner (Philydor fuscipenne), and the White-vented Plumeleteer (Chalybura buffonii). Therefore, private reserves can be appreciated as a suitable conservation tool for bird conservation, and they should not be undervalued because of their smaller size. Buenaventura Reserve is a good example of how private reserves are extremely important in fragmented landscapes, as is the case with tropical forests in Western Ecuador.

ABSTRACT Poaceae is a cosmopolitan family that includes species found in both forest and grassland formations. The objective of this study was to carry out the first floristic survey of Poaceae in the Parque Estadual do Guartelá (PEG), one of the last remnants of native grassland vegetation in the State of Paraná, Brazil, and provide resources to assist the identification of genera and species. The survey was conducted based on field collections and searches in the Species Link online database. In the PEG, Poaceae is represented by 29 genera and 54 species, being Paspalum L. (eight spp.), Andropogon L. (five spp.) and Eragrostis Wolf (four spp.) the richest genera. The number of species in the PEG was incremented by 29 new records. In addition, five species were classified as exotic, five as endemic to Brazil, and two were considered least concern in relation to their conservation. We also present information regarding the distribution, habitat and conservation status for each species.

A catalogue of 126 species of benthic marine brown macroalgae (Phaeophyta) hasbeen compiled for the coastline of tropical–subtropical Queensland,Australia. This number represents a significant decrease compared to the 139brown macroalgal species previously recorded for the State (Lewis 1985).Cutleria mollis Allender & Kraft,Padina gymnospora (KÜtzing) Sonder, andTaonia australasica J.Agardh are newly recorded forQueensland. With the exception of the genus Sargassum, ataxonomically difficult genus in urgent need of revision, misidentificationshave been corrected and erroneous records excluded from the flora. Species ofthe Fucales (59 species), particularly the genusSargassum (51 species), and the Dictyotales (31 species)comprise approximately three quarters of the total number of species recordedand often are ecologically important as dominant species in lower intertidaland subtidal communities. The flora is composed of predominantly tropicalspecies, but also includes temperate species which range into subtropicalsouthern Queensland. However, the geographical ranges of most species remainpoorly documented and little is known of their patterns of abundance orhabitat specificity. Consequently, it is not currently possible to determinethe conservation status of many Queensland brown algal species.

SummaryTheme conflicts of interest is one of the major reasons for concern local government, regional and central administrative and criminal legal implications aiming to uphold the integrity and decisions objectively. Also, most obviously, conflicts of interest occur at the national level where political stakes are usually highest, one of the determining factors of this segment being the changing role of the state itself, which creates opportunities for individual gain through its transformations.
