Geographic variation in walking activity in the red flour beetle Tribolium castaneum

Population Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

GERMINATE. A Generic Database for Integrating Genotypic and Phenotypic Information for Plant Genetic Resource Collections [PDF]

Plant Physiology, 2005
Abstract The extensive germplasm resource collections that are now available for major crop plants and their wild relatives will increasingly provide valuable biological and bioinformatics resources for plant physiologists and geneticists to dissect the molecular basis of key traits and to develop highly adapted plant material to sustain

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

A Constraint Generation Integer Programming Approach to Information Theoretic Sensor Resource Management [PDF]

2007 IEEE/SP 14th Workshop on Statistical Signal Processing, 2007
Many estimation problems involve sensors which can be actively controlled to alter the information received and utilized in the underlying inference task. In this paper, we discuss a novel integer programming method which exploits the submodularity of information theoretic estimation criterion to find an efficient solution to constructing an open loop ...

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

Population Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

Origin of life: β‐sheet amyloid conformers as the primordial functional polymers on the early Earth and their role in the emergence of complex dynamic networks

FEBS Letters, EarlyView.
The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...
