Can aggregate quarry silt lagoons provide resources for wading birds? [PDF]

, 2017
Wading birds have declined across Europe as the intensification of lowland agriculture has resulted in the loss and degradation of wetland areas. Lowland aggregate extraction sites that incorporate areas of fine, waste sediments deposited in silt lagoons

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Lethal injuries on the scaphitid ammonoid Hoploscaphites nicolletii (Morton, 1842) in the Upper Cretaceous Fox Hills Formation, South Dakota, USA

Swiss Journal of Palaeontology
Predator–prey relationships are considered a major driver for the evolution of organisms, and thus contributed to shaping morphology, ecology, and diversity.

Ecological integrity of boreal streams [PDF]

, 2007
Running waters provide a number of services for humans, such as drinking water and food resources and many freshwater animals are confined and specialised to this environment.

Exposure of benthic invertebrates to sediment vibration: From laboratory experiments to outdoor simulated pile-driving [PDF]

Activities directly interacting with the seabed, such as pile-driving, can produce vibrations that have the potential to impact benthic invertebrates within their vicinity.

The Faraday Scalpel: Electrochemical Nerve Lesioning Mechanisms Studied in Invertebrate Models

Advanced Science, EarlyView.
Direct‐current produces nerve lesioning through discrete electrochemical reactions. Using hypoxia‐sensitive locust nerves and hypoxia‐tolerant leech nerves, we map three injury pathways: cathodic oxygen reduction, cathodic alkalization, and anodic chloride oxidation. These findings establish electrochemical lesioning—the “Faraday Scalpel”—as a precise,

Hematological Values of Two Species of Amazonian Caimans, Caiman crocodilus and Melanosuchus niger

Limnological Review
Determining hematological values is essential to provide baseline health and condition data. We evaluated the hematological parameters of free-living individuals of Caiman crocodilus and Melanosuchus niger from the middle Negro River region of Brazil. We

Mitochondrial Enzymes Mimetic Ultrasmall Palladium Nanozymes Prevent Senescence and Neurodegeneration Through Metabolic Reprogramming

Advanced Science, EarlyView.
Simply constructed polyvinylpyrrolidone (PVP) modified palladium nanoparticles (PdP NPs) as cytochrome c oxidase (CcO) and superoxide dismutase (SOD) mimic are promising multifunctional nanoreactors to boost mitochondrial respiration chain function and refine homeostasis via regulation of mitochondrial dynamics and proteostasis sensor UPRmt, which ...

Engineering a Virus‐Derived X Family DNA Polymerase FvPolX for de novo DNA Synthesis

Advanced Science, EarlyView.
In this study, a Faustovirus‐derived polymerase (FvPolX) is engineered based on structural and sequence analysis of PolX enzymes. The optimal mutants demonstrate substantially enhanced catalytic activity toward dNTPs and 3′‐ONH2‐dNTPs compared to the wild‐type enzyme.
