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

open access: yesPopulation 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,

Ecological Economics and Human Ecology [PDF]

open access: yes, 2008
While economic theory has been enormously influential since the eighteenth century, the cultural, political and ethical dominance it has gained in the last few decades is unprecedented. Not only has economic theory taken the place of political philosophy and ethical discourse and imposed its own concepts and image of society on other social sciences ...

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

open access: yesPopulation 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 ...

Studies on the macromycetes of the Janów Forests Landscape Park (SE Poland)

open access: yesActa Mycologica, 2014
The article presents a list of 357 macromycetes species found so far in the Janów Forests Landscape Park (SE Poland), and takes into account their abundance in individual localities categories of threat, and gives a preliminary mycological evaluation of ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

open access: yesPopulation Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Ecology management education social-ecology monitoring

open access: yesRUDN Journal of Ecology and Life Safety, 2010
Social-ecology monitoring is a system of sightings that reflects the social communities' dynamics according to the ecology problematic. The monitoring system of that time realizes some social management functions that define the ways and assets of ...

Principles of Ecology Revisited: Integrating Information and Ecological Theories for a More Unified Science

open access: yesFrontiers in Ecology and Evolution, 2019
The persistence of ecological systems in changing environments requires energy, materials, and information. Although the importance of information to ecological function has been widely recognized, the fundamental principles of ecological science as ...

An Adaptive Management Model for Brown Bears in Hokkaido: Based on Total Population and the Number of Nuisance Bears

open access: yesPopulation Ecology, EarlyView.
Bear management changes management actions according to the horizontal axis of the population size and the vertical axis of the number of nuisance bears. Aiming for the target population size of Ntar, Actions I and II protect the bears, and Action IV reduces the population.

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
