Limited creep-feeding supplementation effects on performance of beef cows and calves grazing limpograss pastures

open access: yesLivestock Science, 2015
Abstract Limpograss ( Hemarthria altissima ) is a warm-season grass used by cow–calf producers in South Florida; however, limpograss protein concentration may limit animal performance. The objective of this study was to test the effects of creep-fed protein supplement on performance of cow–calf pairs grazing limpograss pastures.

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

open access: yesBoreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

The disappearance of malaria from Denmark, 1862–1900

open access: yesThe Economic History Review, EarlyView.
Abstract The reason for malaria's disappearance from northwestern Europe in the early twentieth century has long been discussed but remains an unresolved conundrum. This is partially due to a previous focus on the early modern era, and partially because various theories have never been tested against each other.

Outbreak of poisoning by sodium hydrogen methylarsonate (MSMA)—an arsenic‐based herbicide—in horses in Brazil

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Arsenic poisoning in horses is rarely reported in the literature. However, arsenic compounds can be present in rodenticides, pesticides, and herbicides, representing a potential source of accidental exposure for horses. Objective To describe the epidemiological, clinical, and laboratory findings from a herd of 31 horses exposed to ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

open access: yesMedical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Nutrient addition and herbivore exclusion alter plant traits and biomass via distinct mechanisms: intraspecific variability vs species turnover

open access: yesNew Phytologist, EarlyView.
Summary Soil nutrients and vertebrate herbivory are key ecological factors with opposite and interactive effects on grassland plant traits and biomass. Partitioning trait changes into species turnover and intraspecific change provides a mechanistic linkage between trait shifts and biomass responses.
