Low-density genotype panel for both parentage verification and discovery in a multi-breed sheep population [PDF]

, 2019
peer-reviewedThe generally low usage of artificial insemination and single-sire mating in sheep, compounded by mob lambing (and lambing outdoors), implies that parentage assignment in sheep is challenging.

Pseudorandomised controlled trial of a novel navel barrier solution versus 10% iodine to protect navel and ear tag sites of neonatal lambs

Veterinary Record, EarlyView.
Abstract Background During lambing, 10% iodine is often used to protect neonatal navel and ear tag sites. The evidence for its effectiveness is sparse. Recently, a specific navel barrier solution (NBS) was developed. Here, an in vivo field trial compared the two treatments. Methods Ten farms reported data from 6840 lambs. The navel and ear tag sites of

Effects of genotype and plane of nutrition on growth and carcass characteristics of lambs from hill sheep systems

Animal, 2009
The objective of this study was to determine the effect of lamb genotype and plane of nutrition on post-weaning lamb growth, and carcass characteristics in hill sheep systems.

Challenges in population monitoring: Bar‐tailed Godwits (Limosa lapponica) on the East Atlantic Flyway defy assumed population structure

Ibis, EarlyView.
Estimating and monitoring migratory bird populations involves significant challenges, even in the most well‐studied and easily‐counted species, and can be further complicated by long‐held but unverified assumptions and by shifting distributions in changing flyway conditions.

Dissolved Fe across the Weddell Sea and Drake Passage: impact of DFe on nutrient uptake [PDF]

Biogeosciences, 2014
This manuscript reports the first full depth distributions of dissolved iron (DFe) over a high-resolution Weddell Sea and Drake Passage transect. Very low dissolved DFe concentrations (0.01–0.1 nM range) were observed in the surface waters of the Weddell

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

North-Coast of Texel: A Comparison between Reality and Prediction [PDF]

Coastal Engineering 1998, 1999
For an efficient protection of the north coast of the Dutch Waddensea island Texel, a long dam was constructed in 1995. The position of this dam is on the southern swash platform of the ebb tidal delta of the Eijerlandse Gat: the tidal inlet between the two Waddensea islands Texel and Vlieland. The long dam changed the hydro-morphological conditions in

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

Insect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, Volume 12, Issue 1, February 2026.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.
