Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

open access: yesEcology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Determinants and Consequences of Budget Reallocations*

open access: yesContemporary Accounting Research, Volume 38, Issue 3, Page 1782-1808, Fall 2021., 2021
ABSTRACT We investigate the determinants and consequences of budget reallocations—that is, corrective changes to the budget made during the year. Using proprietary data from a large consumer goods manufacturer, we analyze the extent to which initial budgeting decisions drive reallocations. Examining this relationship is important because initial budget

PICT: A low‐cost, modular, open‐source camera trap system to study plant–insect interactions

open access: yesMethods in Ecology and Evolution, Volume 12, Issue 8, Page 1389-1396, August 2021., 2021
Abstract Commercial camera traps (CTs) commonly used in wildlife studies have several technical limitations that restrict their scope of application. They are not easily customizable, unit prices sharply increase with image quality and importantly, they are not designed to record the activity of ectotherms such as insects. Those developed for the study

A systematic review and meta‐analysis of published cases reveals the natural disease history in multiple sulfatase deficiency

open access: yesJournal of Inherited Metabolic Disease, Volume 43, Issue 6, Page 1288-1297, November 2020., 2020
Abstract Multiple Sulfatase Deficiency (MSD, MIM#272200) is an ultra‐rare lysosomal storage disorder arising from mutations in the SUMF1 gene, which encodes the formylglycine‐generating enzyme (FGE). FGE is necessary for the activation of sulfatases, a family of enzymes that are involved in the degradation of sulfated substrates such as ...

Intermittent pneumatic compression versus additional prophylaxis with enoxaparin for prevention of venous thromboembolism after laparoscopic surgery for gastric and colorectal malignancies: multicentre randomized clinical trial

open access: yesBJS Open, Volume 4, Issue 5, Page 804-810, October 2020., 2020
This RCT compared intermittent pneumatic compression (IPC) alone with IPC plus enoxaparin for 1 week after surgery in the prevention of venous thromboembolism (VTE) in patients undergoing laparoscopic surgery for gastric or colorectal malignancy. Although VTE occurred in 4·8 per cent of the ICP‐alone group and 3·3 per cent of the ICP with enoxaparin ...

Modelling of cellular materials by a microsphere‐based material model

open access: yesPAMM, Volume 19, Issue 1, November 2019., 2019
Abstract Metal foams are a very interesting class of cellular materials which, due to their structure, can be used both for lightweight construction and for the absorption of kinetic energy. They have a microheterogeneous structure, which makes it difficult to simulate these materials efficiently.
