DESCRIÇÃO DA CURVA DE CRESCIMENTO DE FRUTOS DO CAJUEIRO POR MODELOS NÃO LINEARES

open access: yes, 2016
O objetivo do trabalho foi avaliar o ajuste dos modelos Gompertz e Logistico, com estrutura de erros independentes e autoregressivos, no desenvolvimento de frutos de caju, com base em medidas de comprimento e largura do fruto, tomados ao longo do tempo ...

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Influência das cargas selecionadas na determinação da potência crítica determinada no ergômetro de braço em dois modelos lineares

open access: yes, 2000
The aim of this study was to verify the effect of selected loads and the model used to determine CP in the arm ergometer. Eight active males apparently healthy participated in the study. The subjects performed 4 tests with constant loads maintained until

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响

open access: yesConservation Biology, EarlyView.
Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Modelos lineares generalizados para análise de dados com medidas repetidas

open access: yes, 2003
In this work, we consider the generalized estimation equations developed by Liang and Zeger (1986) focusing the theory of estimating functions presented by Godambe (1991). These estimation equations are an extension of generalized linear models (GLMs) to

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

TAXA DE CÂMBIO E AJUSTE EXTERNO: UMA INVESTIGAÇÃO COM MODELOS ARDL PARA AS ECONOMIAS EMERGENTES DO BRICS

open access: yesRevista de Economia Contemporânea, 2019
RESUMO O objetivo deste trabalho é investigar o papel da taxa de câmbio (nível, desalinhamento e volatilidade) para o ajuste externo dos BRICS (1998 a 2015) usando modelos ARDL.
