Monitoring of sex and age ratios in ungulate populations of the Kruger National Park by ground survey

open access: yesKoedoe: African Protected Area Conservation and Science, 1990
Objectives, techniques and problems of monitoring ungulate population structure and trends using standardised ground surveys as an adjunct to aerial counts are described and discussed in the light of experience gained over the past seven years.

Spatial ecology of long‐tailed ducks and white‐winged scoters wintering on Nantucket Shoals

open access: yesEcosphere, 2020
We examine the long‐term co‐occurrence of long‐tailed ducks (Clangula hyemalis) and white‐winged scoters (Melanitta fusca) wintering at the Nantucket Shoals off Massachusetts, USA, and ask: (1) What oceanographic features attract these aggregations?

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

2002 Aerial Surveys of Grey Seals in the Northeastern United States

open access: yesNAMMCO Scientific Publications, 2007
In the past 20 years, grey seals have become established in coastal waters of the Northeastern United States. There are 3 sites where pupping and breeding occurs in January and February, 2 in Maine and 1 in Massachusetts. In 2002 we recorded a minimum of

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
