Environmental improvement and conservation of useful pastures for wild herbivores in a Regional Park on the Apennines mountains

Italian Journal of Animal Science, 2010
In order to investigate some effects of the environmental management with faunistic purpose on pastures located on the Apennines mountains, in open areas subjected to bracken fern (Pteridium aqulinum) infestation, samples of vegetation were taken for ...

Evaluating the accuracy of the EcoservR toolkit for fine‐resolution habitat mapping

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Accurate habitat maps are essential for monitoring ecological change and supporting nature recovery planning. We evaluate the EcoservR rule‐based habitat mapping toolkit using field survey data from Merseyside and the North York Moors, validating classifications across the Joint Nature Conservation Committee (JNCC) Phase 1 hierarchy.

Forest Disturbance Drives Changes in the Functional Traits of Soil Bacteria: A Metagenomic Study of Kauri (Agathis australis) Forest Ecosystems

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study reveals how ecological disturbances reshape the structure and function of soil bacterial communities in kauri forests, which are critical for ecosystem resilience. By linking disturbance regimes to shifts in bacterial diversity and functional capacity, it highlights the wider effects of ecosystem disturbance on soil ecological function ...

Bovine papillomavirus type 2 detection in the urinary bladder of cattle with chronic enzootic haematuria

Memorias do Instituto Oswaldo Cruz, 2006
The bovine papillomavirus type 2 (BPV-2) involvement in the aetiology of chronic enzootic haematuria associated to bracken fern ingestion has been suggested for a long time.

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, Volume 41, Issue 3, Page 400-418, April 2026.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Differences in bird and bat traits, seed-dispersal interactions and functions between tropical montane forest and bracken-dominated areas

Frontiers in Ecology and Evolution
Most tropical plant species depend on animals to disperse their seeds. Seed dispersal by animals allows plants to colonize new sites in deforested habitats helping to accelerate forest recovery.

Post‐fire vegetation shifts: Role of invasives and seedbanks in an Australian grassy woodland ecosystem

Journal of Ecology, Volume 114, Issue 4, April 2026.
Wildfire and invasive species interact in a south‐eastern Australian grassy woodland, with the soil seedbank introducing predominantly non‐native species into the extant vegetation after fire. This influx can temporarily increase ecosystem flammability and promote a grass–fire cycle.

Toxicities of bracken fern in guinea pigs.

The Japanese Journal of Veterinary Science, 1983
Toxicities of bracken fern were studied for feeding periods of 5-1O days (experiment A), 20-80 days (experiment B) and 11-15 months (experiment C) in 149 albino female and male guinea pigs weighing approximately 200g. Guinea pigs were fed ad lib. the bracken diet containing 30% (Wt./Wt.) dry powdered young fronds, 0.012% thiamine and 0.01% ascorbic ...

Detecting Pteridium arachnoideum and Tithonia diversifolia in a Multiclass Land‐Cover Framework in the Cerrado: A Deep Learning Time‐Series Benchmark With Spatial Cross‐Validation

Transactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...

Evaluation of urine dipstick and cystoscopy in bovine enzootic haematuria

Semina: Ciências Agrárias, 2014
Enzootic bovine haematuria is mainly caused by the chronic ingestion of bracken fern and is still considered an important cause of economic losses in beef herds, particularly in large metropolitan areas of Brazil that are not suitable for agriculture ...
