Integrating presence‐only and presence–absence data to model changes in species geographic ranges: An example in the Neotropics

Journal of Biogeography, Volume 50, Issue 9, Page 1561-1575, September 2023., 2023
Abstract Aim Anthropogenic changes such as land use and climate change affect species' geographic ranges, causing range shifts, contractions, or expansions. However, data on range dynamics are insufficient, heterogeneous, and spatially and temporally biased in most regions.

The asymmetric effect of fiscal policy on private consumption and private investment over a business cycle: Evidence from Sub‐Saharan African countries

Regional Science Policy &Practice, Volume 15, Issue 6, Page 1147-1162, August 2023., 2023
Abstract This study examines the response of private consumption and private investment to an exogenous shock of fiscal policy and estimates the size of fiscal multipliers during periods of economic slacks and positive output gap. Panel vector autoregressive (VAR) estimation technique is performed on a sample of 18 Sub‐Saharan African (SSA) countries ...

Implications of fetal premature atrial contractions: systematic review

Ultrasound in Obstetrics &Gynecology, Volume 60, Issue 6, Page 721-730, December 2022., 2022
ABSTRACT Objective Fetal heart‐rate irregularities occur in 1–2% of pregnancies and are usually caused by premature atrial contractions (PAC). Although PAC are considered benign, they may be associated with cardiac defects and tachyarrhythmia. We aimed to determine the incidence of congenital heart defects (CHDs) and complications in fetuses with PAC ...

Population estimates and trends of three Maui Island‐endemic Hawaiian Honeycreepers

Journal of Field Ornithology, Volume 92, Issue 2, Page 115-126, June 2021., 2021
Abstract Population monitoring is critical for informing the management and conservation of rare Hawaiian forest birds. In 2017, we used point‐transect distance sampling methods to estimate population densities of birds on Haleakalā Volcano on east Maui island.

Measuring policy debate in a regrowing city by sentiment analysis using online media data: A case study of Leipzig 2030

Regional Science Policy &Practice, Volume 13, Issue 3, Page 675-692, June 2021., 2021
Abstract In a time of data science, online crowdsourced data and advanced data analytics would be a waste of resources and knowledge if these tools wouldn't assist urban planning. This paper uses sentiment analysis to understand policy debates' present in online media in a re‐urbanized city and discusses how these tools and new datasets can help ...

Factors influencing occupancy and density of salt marsh songbirds in northeast Florida

Journal of Field Ornithology, Volume 91, Issue 2, Page 156-169, June 2020., 2020
Abstract Salt marshes and the organisms that depend on them are subject to a variety of anthropogenic threats. In Florida, Worthington’s Marsh Wrens (Cistothorus palustris griseus) and MacGillivray’s Seaside Sparrows (Ammospiza maritima macgillivraii) are species of concern that inhabit a small, narrow range of salt marsh in the northeastern corner of ...

Opposing genetic patterns of range shifting temperate and tropical gastropods in an area undergoing tropicalisation

Journal of Biogeography, Volume 51, Issue 2, Page 246-262, February 2024.
Abstract Aim The poleward range expansion of tropical species, and range contraction of temperate species (known as tropicalisation) has mainly been studied from an ecological perspective, with little research on its genetic consequences. Here, we used distributional and genetic data to document the consequences of tropicalisation in rocky shore ...
