‘Flying barnacles’: implications for the spread of non-indigenous species [PDF]

open access: yesBiofouling, 2010
The presence of adult barnacles of Fistulobalanus pallidus (Darwin) and Fistulobalanus albicostatus (Pilsbry) attached to field-readable plastic leg rings on the Lesser Black-backed Gull Larus fuscus in Northern Europe is reported. L. fuscus is a long-distance palaearctic migrant, breeding in temperate areas spreading widely over inland and marine ...

Eimeria species occurrence varies between geographic regions and poultry production systems and may influence parasite genetic diversity [PDF]

open access: yes, 2017
Coccidiosis is one of the biggest challenges faced by the global poultry industry. Recent studies have highlighted the ubiquitous distribution of all Eimeria species which can cause this disease in chickens, but intriguingly revealed a regional divide in

Can species richness be maintained in logged endemic Acacia Heterophylla forests (Reunion Island, Indian Ocean) ? [PDF]

open access: yes, 2007
It is assumed that forests can serve multiple uses, including wood production and maintenance of high biodiversity level. We tested this hypothesis by studying eradication methods of invasive plants currently implemented in exploited endemic Acacia ...

Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

open access: yesAdvanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Ecological risk assessment of chlorpyrifos in Laizhou Bay based on species sensitivity distributions analysis

open access: yesEcological Indicators
Chlorpyrifos, a widely used organophosphorus insecticide, poses a potential hazard to marine ecosystems due to its toxicity to aquatic organisms. However, the ecological risks of chlorpyrifos to marine organisms remain unclear.

Freshwater fish assemblages in Cyprus with emphasis on the effects of dams [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2012
Background. The distribution of freshwater fishes in Cyprus is poorly known. The island is particularly interesting because of its biogeographical isolation and the long-term influence of humans on the biota, especially due to the recent damming of many ...

Grizzly and polar bears as nonconsumptive cultural keystone species

open access: yesFACETS, 2021
Grizzly bears and polar bears often serve as ecological “flagship species” in conservation efforts, but although consumptively used in some areas and cultures they can also be important cultural keystone species even where not hunted.
