TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

Ingestive behavior and nitrogenous compounds balance of heifers on pastures of Urochloa brizantha cv. Marandu deferred and fertilized with nitrogen

Objetivou-se com este estudo avaliar o efeito de diferentes doses de nitrogênio em pastos de Urochloa brizantha cv. Marandu diferidos, e suas implicações sobre o comportamento ingestivo e o balanço de compostos nitrogenados de novilhas Nelore. Utilizou-se o delineamento inteiramente ao acaso, com quatro tratamentos (doses de nitrogênio) e quatro repetições (número de piquetes adubados). Foram utilizadas 16 novilhas da raça Nelore, com média de oito meses de idade e com peso corporal inicial de 178,69 ± 26,67 kg, sendo quatro novilhas por tratamentos. Os resultados foram avaliados por meio de análise de variância e regressão a 5% de probabilidade. As atividades comportamentais dos animais não se alteraram (P > 0,05) com o uso das diferentes doses de nitrogênio nos pastos com tempos médios de 576,25 minutos (10h:00min) em pastejo, 509,84 minutos (8h:50min) em ruminação, 315,16 minutos (5h:25min) em ócio e 39 minutos alimentando no cocho. Para o nitrogênio ingerido, nitrogênio digerido e o nitrogênio retido (g/dia) e o nitrogênio digerido (% do N ingerido), houve efeito linear crescente (P 0,05) das doses de nitrogênio, com média de 15,79 mg/dL. As atividades comportamentais das novilhas não são afetadas pelas doses de nitrogênio em pastos de Urochloa brizantha cv. Marandu diferidos. O nitrogênio ingerido, nitrogênio retido (g/dia), o nitrogênio digerido (g/dia) e (% do N ingerido), a concentração de nitrogênio ureico na urina, e as excreções de ureia e de nitrogênio ureico na urina são influenciados pela quantidade crescente de proteína bruta na forragem oriundas da adução nitrogenada, nas condições de realização desta pesquisa.This study has to evaluate the effect of different levels of nitrogen in pastures Urochloa brizantha cv. Marandu deferred, and its implications on feeding behavior and the nitrogen balance of Nelore heifers. The design was used completely randomized, with four treatments (nitrogen of levels) and four replications (number of fertilized paddocks). Were used 16 heifers Nellore, averaging eight months of age and initial body weight of 178.69 ± 26.67 kg, 4 heifers for treatments. The results were evaluated by analysis of variance and regression at 5% probability. The nitrogen levels did not influence the behavioral activities with average time of 576.25 minutes (10:00) grazing, 509.84 minutes (8h50min) in rumination, 315.16 minutes (5h25min) in idle and 39 minutes in the feeding trough. For nitrogen intake, digested nitrogen and the nitrogen retention (g/day) and the digested nitrogen (%N ingested), there was increasing linear effect (P 0.05) nitrogen in the feces and urine nitrogen (g/day), and not the nitrogen retention (% of N ingested) and nitrogen retention (% of digested N), whose mean values were 22.98 g/day; 39.48 g/day; 46.83% and 78.10%, respectively. For N urea in urine, there was increasing linear effect (P0.05) of nitrogen rates, averaging 15.79 ml/dL. The behavioral activities of the heifers are not affected by nitrogen levels in pastures Urochloa brizantha cv. Marandu deferred. The ingested nitrogen, retained nitrogen (g/day), digested nitrogen (g/day) (% of ingested N), the urea nitrogen in urine, excretion in urine urea and urea nitrogen in urine are influenced by the amount increasing crude protein forage derived nitrogen adduction, these results are important to prevent the economic losses due to excessive supply of protein in the diet.

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set.

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

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.
