Avaliação genética em erva-mate pelo procedimento BLUP individual multivariado sob interação genótipo x ambiente

The objectives of this paper were to estimate genetic and phenotypic parameters and to predict breeding values for parents and provenances of Ilex paraguariensis. Eight provenances with 164 progenies were evaluated on three sites (Ivaí, PR, Guarapuava, PR and Rio Azul, PR) for the trait leaf weight (LW). All the variance components, parameters and breeding values were obtained by REML/BLUP (restricted maximum likelihood/best linear unbiased prediction) procedure at the individual level, through multivariate analysis involving the three sites. The individual strict sense heritabilities for the trait LW were 0.15 in Ivaí, 0.62 in Guarapuava and 0.23 in Rio Azul, demanding more sophisticated selection methods in Ivaí and Rio Azul. The provenance effect was significant in Ivaí and Rio Azul, with intraclass phenotypic correlation of 0.13 in Ivaí and 0.09 in Rio Azul. The provenances were more stable across sites than progenies with genetic correlation of 0.95 between the sites Ivaí and Rio Azul. Genetic values for all provenances and parents in all sites were predicted for the trait LW. The best provenances are Barão de Cotegipe, Quedas do Iguaçu, Cascavel and Ivaí.Os objetivos deste trabalho foram estimar parâmetros genéticos e fenotípicos e realizar a predição de valores genéticos de matrizes e procedências de erva-mate (Ilex paraguariensis). Foram avaliadas 164 progênies de oito procedências, em três locais (Ivaí, PR, Guarapuava, PR e Rio Azul, PR), em relação ao caráter produção de massa foliar (PMF). Os componentes de variância, parâmetros genéticos e valores genéticos foram estimados pelo procedimento REML/BLUP individual (máxima verossimilhança restrita/melhor predição linear não viciada), realizando a análise multivariada para os três locais. Os coeficientes de herdabilidade individual, no sentido restrito, para o caráter PMF foram 0,15 em Ivaí, 0,62 em Guarapuava e 0,23 em Rio Azul. A baixa magnitude desses coeficientes em Ivaí e Rio Azul demanda a utilização de métodos de seleção que utilizem todos os efeitos aleatórios do modelo estatístico. O efeito de procedências foi significativo em Ivaí e Rio Azul, com correlação fenotípica intraclasse de 0,13 em Ivaí e de 0,09 em Rio Azul. As procedências apresentaram correlação genética de 0,95 entre os locais Ivaí e Rio Azul. Nesses locais, as procedências foram mais estáveis nos diferentes ambientes do que as progênies. Foram preditos os valores genéticos em relação a todas as procedências e matrizes em todos os locais quanto ao caráter avaliado. As melhores procedências são Barão de Cotegipe, Quedas do Iguaçu, Cascavel e Ivaí

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
