A cost-effective method for rapid identification of the southern muriqui (Brachyteles arachnoids: a contribution for the control of illegal bushmeat trade Mastozool. neotrop.
Valões Cardoso,M. Luiza; Ferreira,Paula B; Wanderley,Artur M; Torres,Rodrigo A; Talebi Gomes,Mauricio; Teixeira,Rodrigo H. F; Duarte,José M. B; Garcia,José E.
To control illegal wildlife-product trade and protect endangered species of animals, unambiguous identification of the captured specimens is essential. Forensic genetic tools have contributed to identify animal species for conservation purposes promoting accurate results for informing public policies and management of the biodiversity. The southern muriqui (Brachyteles arachnoides) is the largest non-human primate of the Neotropical region and is critically endangered (IUCN Red List of Threatened Species), mainly due to the illegal hunting for bushmeat. In this study, we describe a molecular method using PCR/RFLP to differentiate between bushmeat of southern muriqui and the meat of the domestic animals most commonly consumed in Brazil (Bos taurus, Ovis...

Analysis of geographic and taxonomic groups informs conservation of Rhododendron subgenus Vireya (Ericaceae) Naturalis
MacKay, M.; Smith, G.; Gardiner, S.E..
Although Rhododendron subg. Vireya, comprising 400 taxa, is one of the largest plant genera in Southeast Asia, with taxa found throughout the region, it has a significant conservation problem, with conservation status assessments in 2011 and 2015 placing 201 taxa in an IUCN Red List threat category. Plant conservation is driven by the Global Strategy for Plant Conservation, with Target 8 requiring 75 % of threatened plant taxa to be conserved in ex situ collections, by 2020. To date there has been limited analysis of conservation priorities for subg. Vireya, or any consideration of how its geographic characteristics, complex taxonomy, and existing ex situ collections might influence priorities. We analyse the IUCN Red List status of geographic origins and...

Bird diversity and conservation in the southern coast of Santa Catarina state, Brazil Pap. Avulsos de Zool. (São Paulo)
Just,João Paulo Gava; Rosoni,Jonas Rafael Rodrigues; Romagna,Rafael Spilere; Zocche,Jairo José.
Abstract Coastal lagoons and their surrounding habitats often harbour high biodiversity and some of the most threatened ecosystems in the world. However, in the Neotropics the biodiversity is often poorly described, lacking even inventories of species which therefore limits the assessment of threats and the stablishment of efficient conservation measures. We present here lists of bird species recorded at ten sites along the under-studied coastal lagoons of southern Santa Catarina, Brazil, collected mainly from October 2012 to March 2018. We present quantitative data for endemic and threatened species, identify migratory status and highlight distributional novelties. In total, we recorded 229 species encompassing 63 families, including twelve species of...

Body weight-length relationships in giant otters (Pteronura brasiliensis) (Carnivora, Mustelidae) BABT
Rosas,Fernando César Weber; Rocha,Carla Soares da; Mattos,Gália Ely de; Lazzarini,Stella Maris.
Few giant otters (Pteronura brasiliensis) have been measured and weighed and its actual size is controversial in the literature. This study presents the weight-length relationship of Amazonian giant otters using 15 captive individuals. The maximum length and weight were 163cm and 22.5kg, and 162cm and 28.8kg, for the males and females, respectively. The weight-length relationships were not significantly different between the sexes (t = 0.658, d.f.=11, P>0.05) and can be expressed by the equation: W=1.48x10-5 L2.81. Considering that some of the giant otters used in this study were old individuals (more than 10 years old), and that all the animals analyzed were healthy, it is possible to assume that the weight-length relationships obtained are probably a...

Butterflies (Lepidoptera: Papilionoidea) from the campos rupestres of Serra de São José, Minas Gerais, Brazil Biota Neotropica
Henriques,Nathália Ribeiro; Beirão,Marina do Vale; Brasil,Ello; Cornelissen,Tatiana.
Abstract We provide the first inventory of butterfly species (Lepidoptera: Papilionoidea) in Serra de São José, Minas Gerais, Brazil. Serra de São José has elevations ranging from 800 m to 1,400 m above sea level; the butterflies were sampled using traps and entomological nets in seven plots along the altitudinal gradient. We recorded 647 butterflies belonging to 112 species and six families. We also recorded one threatened species and three endemic species for the Cerrado domain, which suggests that Serra de São José is an important refuge for butterfly conservation.

Bycatch fauna of seabob shrimp trawl fisheries from Santa Catarina State, southern Brazil Biota Neotropica
Branco,Joaquim Olinto; Freitas Júnior,Felipe; Christoffersen,Martin Lindsey.
Marine communities in tropical regions contain a great diversity of species that play key roles in ecological processes. The observed bycatch fauna in artisanal fishing for the seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) in the southwest Atlantic exceeds the quantity of commercial shrimp captured. This bycatch has not been previously inventoried extensively in Brazil, particularly in the State of Santa Catarina, where small-scale shrimp fisheries is a traditional activity and dominates the local fishing economy. Six municipalities were sampled three times a month, from 1996 to 2011, yielding 216 species belonging to the bycatch (7 cnidarians, 22 mollusks, 42 crustaceans, 11 echinoderms, and 134 fishes). Bycatch management is a pressing aspect of...

Climate and land-use changes effects on the distribution of a regional endemism: Melanophryniscus sanmartini (Amphibia, Bufonidae) Iheringia, Sér. Zool.
Rosenstock,Nicole; Toranza,Carolina; Brazeiro,Alejandro.
ABSTRACT Amphibians are the most threatened vertebrate group according to the IUCN. Land-use and land cover change (LULCC) and climate change (CC) are two of the main factors related to declining amphibian populations. Given the vulnerability of threatened and rare species, the study of their response to these impacts is a conservation priority. The aim of this work was to analyze the combined impact of LULCC and CC on the regionally endemic species Melanophryniscus sanmartini Klappenbach, 1968. This species is currently categorized as near threatened by the IUCN, and previous studies suggest negative effects of projected changes in climate. Using maximum entropy methods we modeled the effects of CC on the current and mid-century distribution of M....

Effects of forest structure components on the occurence, group size and density of groups of bare-face tamarin (Saguinus bicolor - primates: Callitrichinae) in Central Amazonia Acta Amazonica
Vidal,Marcelo Derzi; Cintra,Renato.
This study analyzed the influence of forest structural components on the occurence, size and density of groups of Bare-face Tamarin (Saguinus bicolor) - the most threatened species in the Amazon - and produced the first map of distribution of groups in large-scale spatial within the area of continuous forest. Population censuses were conducted between November 2002 and July 2003, covering 6400 hectares in the Ducke Reserve, Manaus-AM, Brazil. Groups of S. bicolor were recorded 41 times accordingly distributed in the environments: plateau (20); slopes (12); and lowlands (09). The mean group size was 4.8 indiv./group, and ranged from 2 to 11 individuals. In the sites where the groups were recorded, and in an equivalent number of sites where no tamarins were...

Estudo de uma população relictual de veado-campeiro, Ozotoceros bezoarticus (Linnaeus) (Artiodactyla, Cervidae) no municipio da Lapa, Paraná, Brasil Zoologia
Moura-Britto,Fernanda Góss Braga Mauro de; Margarido,Tereza Cristina Castellano.
The pampas deer, Ozotoceros bezoarticus (Linnaeus, 1758) was studied between August 1996 and September 1997 at Fazenda Santa Maria (25º34' and 25º36'S, 49º46'and 49º49'W) at Lapa, Paraná State. During that period we have collected information on feeding habits, group composition, time of the year for birth of youngsters and time for antlers change. The presence of the animal in the area was confirmed by the finding of vestiges and visual occurrences. Animais were observed feeding on young leaves of soya been (Glicine max), oat (Avenasaliva), ryegrass (Lolium mulliflorum) and barley (Hordeum vulgare). Only one female was observed feeding on dry leaves. A stag was observed feeding on a barley ear. Group's average size was 1.5 individual. Stags/female...

Financing threatened species management: the costs of single species programmes and the budget constraint AgEcon
Moran, Emma; Cullen, Ross; Hughey, Kenneth F.D..
In New Zealand total annual funding allows 15 percent of the 2,400 threatened species to be targeted for management. Although management costs are crucial to a conservation organisation's ability to achieve its goals, estimates of costs are not usually included in applications for funding or the preparation of recovery plans. Cost is also not generally a factor in priority ranking systems and cost-effectiveness analysis is rarely conducted. Using the results of analysis of 11 single species programmes for 2003-2012, this paper investigates the costs of management. It also considers the impact of the budget constraint on outcomes, cost-effectiveness, and investment.

Floristic and vegetation structure of a granitic grassland in Southern Brazil Rev. Bras. Bot.
Ferreira,Pedro Maria de Abreu; Müller,Sandra Cristina; Boldrini,Ilsi Iob; Eggers,Lilian.
A floristic and structural survey of a natural grassland community was conducted on Morro do Osso, a granitic hill in Porto Alegre, RS, Brazil. Structural data were surveyed in 39 one square meter plots placed over two major grassland areas. An accidental fire has occurred in one of the areas approximately one year prior to our survey, leading to further analysis of parameters differences between sites. The floristic list contains 282 species, whereas the structural survey has found 161 species. Families with highest accumulated importance values were Poaceae, Asteraceae and Fabaceae. The diversity and evenness indexes were 4.51 nats ind-1 and 0.86, respectively. Cluster analysis denoted two groups coinciding with the areas distinguished by the fire...

GAPeDNA: Assessing and mapping global species gaps in genetic databases for eDNA metabarcoding ArchiMer
Marques, Virginie; Milhau, Tristan; Albouy, Camille; Dejean, Tony; Manel, Stéphanie; Mouillot, David; Juhel, Jean‐baptiste; Dutta, Trishna.
Aim Environmental DNA metabarcoding has recently emerged as a non‐invasive tool for aquatic biodiversity inventories, frequently surpassing traditional methods for detecting a wide range of taxa in most habitats. The major limitation currently impairing the large‐scale application of eDNA‐based inventories is the lack of species sequences available in public genetic databases. Unfortunately, these gaps are still unknown spatially and taxonomically, hindering targeted future sequencing efforts. Innovation We propose GAPeDNA, a user‐friendly web interface that provides a global overview of genetic database completeness for a given taxon across space and conservation status. As an application, we synthetized data from regional checklists for marine and...

Genetic diversity and population structure of naturally rare Calibrachoa species with small distribution in southern Brazil Genet. Mol. Biol.
John,Ana Laura de Wallau; Mäder,Geraldo; Fregonezi,Jeferson N.; Freitas,Loreta B..
Abstract Calibrachoa is a South-American genus comprising 27 species, several considered endemic or rare; few were subjects in genetic studies. We attempted to generate new data about the phylogenetically related and rare species C. eglandulata, C. sendtneriana, C. serrulata, and C. spathulata concerning their genetic diversity and population structure, which, coupled with their known restricted distribution, could help access their conservation status and contribute to the study of the Brazilian biodiversity. We sequenced 88 individuals for plastid intergenic spacers and genotyped 186 individuals for five microsatellite loci. Compared among each other, C. sendtneriana and C. serrulata presented the highest values of genetic diversity [π% (sd) = 0.23...

Geographic analysis of Red List Rhododendron (Ericaceae) taxa by country of origin identifies priorities for ex situ conservation Naturalis
MacKay, M.B.; Gardiner, S.E..
A Red List assessment is insufficient to determine priorities for ex situ conservation in large genera such as Rhododendron, where there may be hundreds of taxa in any one Red List category. We have utilised an analysis of the geographic origins of 1?215 taxa of Rhododendron (Ericaceae) as a method to prioritise Red List taxa for ex situ conservation. This analysis includes descriptions of distribution and endemism by country of origin, analysis of the incidence of the 715 Red List taxa by country of origin, and determination of the extent to which taxa from each country of origin are in cultivation. We determined that of 30 countries of origin and a ‘Europe’ aggregate, 24 origins contain Red List taxa. Of those 24 origins, 17 origins and ‘Europe’ have...

Habitat structure and their influence in lizard’s presence Pap. Avulsos de Zool. (São Paulo)
Cosendey,Beatriz Nunes; Rocha,Carlos Frederico Duarte da; Menezes,Vanderlaine Amaral de.
Abstract Many species are declining due to environmental and physical changes in their habitats. Such disturbs alter the availability of micro-habitats and influences the presence of lizards, being even worse for threatened and endemic species. Glaucomastix littoralis is a teiid species restricted to four restingas areas of Brazil. The understanding about the use and preferences of micro-habitats by the species and the consequents effects of substrate loss is important to prevent local extinctions. This study took place in restingas of Maricá, Jurubatiba and Grussaí, in Rio de Janeiro State. We sampled the vegetation of all areas, to access differences between the physical structures, and recorded the individuals sighted and the micro-habitat they were in,...

Hymenostegia viridiflora (Detarieae, Caesalpinioideae, Leguminosae), a new tree species from Cameroon Naturalis
Mackinder, B.A.; Wieringa, J.J..
A new species of Hymenostegia (Detarieae, Caesalpinioideae, Leguminosae) is described from Cameroon. Hymenostegia viridiflora has previously been confused with the type species of the genus, H. floribunda, but differs from it in having pale green to greenish yellow instead of lemon yellow petals, a broader upper part of the stipule, more numerous reddish veins on the white bracteoles and generally more numerous and narrower leaflets. As a consequence, the geographic range of true H. floribunda no longer includes Cameroon. Hymenostegia viridiflora is assessed as Vulnerable according to the criteria of IUCN.

Ichthyofauna of the “Cachoeira de São Roberto” and fishes of lower Preto River, upper Paraná River basin, Brazil Biota Neotropica
Santos,Ana Cláudia; Gonçalves,Carla Cristina; Carvalho,Fernando Rogério.
Abstract Rheophilic environments typically houses fish species with specific ecological requirements. Thus, the suppression of these environments can lead to damaging impacts to local and regional fauna. In this work the ichthyofauna of the “Cachoeira de São Roberto” was inventoried, with a historical review of fish collected in the lower Preto River basin. The sampling sites included two reaches (named R1 and R2): R1 in the “Cachoeira de São Roberto” and R2 refers to two km upstream. The fishes were sampled bimonthly during one year (April 2013 to February 2014) using small and dip nets. Voucher specimens were catalogued in the Fish Collection of “Departamento de Zoologia e Botânica do Instituto de Biociências, Letras e Ciências Exatas, Universidade...

Knowledge about a Species' Conservation Status and Funding for its Preservation: Analysis AgEcon
Tisdell, Clement A..
Using a species’ population to measure its conservation status, this note explores how an increase in knowledge about this status would change the public’s willingness to donate funds for its conservation. This is done on the basis that the relationship between the level of donations and a species’ conservation status satisfies stated general mathematical properties. This level of donation increases, on average, with greater knowledge of a species’ conservation status if it is endangered, but falls if it is secure. Game theory and other theory is used to show how exaggerating the degree of endangerment of a species can be counterproductive for conservation.
