Relationships between individual behaviour and morphometry under different experimental conditions of temperature and feeding in glass eels (Anguilla anguilla) [PDF]

Knowledge and Management of Aquatic Ecosystems, 2008
After Anguilla anguilla larvae reach the European coast, metamorphosing glass eels exhibit an estuarine migration phase and can potentially colonize the continental area.

The effects of overwintering, sex, year, field identity and vegetation at the boundary of fields on the body condition of Anchomenus dorsalis (Coleoptera: Carabidae)

European Journal of Entomology, 2014
Body condition, in terms of body mass corrected for structural body size, represents an animal s energetic reserves and is an indicator of the health and fitness of an organism. This study investigates the variability in the body condition of the carabid

Applicability of self-consistent mean-field theory

, 2004
Within the constrained Hartree-Fock (CHF) theory, an analytic condition is derived to estimate whether a concept of the self-consistent mean field is realized or not in level repulsive region. The derived condition states that an iterative calculation of

The effect of breed and parity on curves of body condition during lactation estimated using a non-linear function

Animal, 2007
The objectives of this study were to see if the body condition score curve during lactation could be described using a model amenable to biological interpretation, a non-linear function assuming exponential rates of change in body condition with time ...

Humpback whale (Megaptera novaeangliae) maturity and body condition in Ireland, Norway and Cabo Verde based on UAS photogrammetry data

Frontiers in Marine Science
Animal morphometrics are essential for understanding a species’ life history and its ecological interactions with the environment. This study investigates the maturity status and body condition of humpback whales (Megaptera novaeangliae) across ...

On the distribution of proportions and ratios as indicators of ungulate body condition [PDF]

, 2007
In the wildlife literature various studies have shown that the amount of fat around the kidneys is often a good indicator of body condition and health of ungulate species ([1],[2]).

Working donkey welfare assessment and owner survey in Meru County, Kenya

Animal Welfare
There are significant welfare concerns regarding the plight of working donkeys (Equus asinus) in developing countries. To-date, however, there has been limited work assessing the welfare of donkeys in many parts of Africa, including Kenya.

The complex relation between production and scattering amplitudes

, 2007
The unitarity relation, Im(A)=T* A, is derived for a three-body production amplitude, A, that consists of a complex linear combination of elements of the two-body scattering amplitude, T. We conclude that the unitarity relation does not impose a realness

Fall bird migration in western North America during a period of heightened wildfire activity

Avian Conservation and Ecology, 2022
Billions of birds annually migrate between breeding and nonbreeding grounds in North America. During fall 2020, there was a series of alarming mass-mortality events of migratory birds across the western United States, with estimates of 100,000 to 1 ...

The Applicability of Nonlinear Systems Dynamics Chaos Measures to Cardiovascular Physiology Variables [PDF]

, 1991
Three measures of nonlinear chaos (fractal dimension, Approximate Entropy (ApEn), and Lyapunov exponents) were studied as potential measures of cardiovascular condition.
