Fruit flies (Diptera: Tephritidae) are devastating agricultural pests worldwide but studies on their long-term population dynamics are sparse. Our aim was to determine the mechanisms driving long-term population dynamics ...

We present a perturbative formalism to deal with linear random positive maps. We generalize the biological concept of the population growth rate when a Leslie matrix has random elements (i.e. characterizing the macroscopic ...

This study proposes a delay-coupled system based on the logistic equation that models the interaction of a population with its varying environment. The integro-diferential equations of the model are presented in terms of ...

Modification of natural environments due to human activities has become an issue of great concern in the last years. In this study, beach urbanization impact was assessed through population dynamics of two dominant infaunal ...

In the development of management measures for sustainable fisheries, estimating the natural mortality rate and recruitment are fundamental. In northern Patagonia, Argentina, the southern geoduck, Panopea abbreviata, a ...

The success of control programs for mosquito-­borne diseases can be enhanced by crucial information provided by models of the mosquito populations. Models, however, can differ in their structure, complexity, and biological ...

Leptospirosis is a public health problem whose main vectors are rodents. The main objective of this work is to study the dynamics of this zoonosis considering the interactions between rodents and humans. We assume that the ...

Global losses of oyster populations urgently necessitate evaluating the status of underdocumented populations. The north-Patagonian Ostrea puelchana metapopulation changed in recent decades: certain beds grew and expanded; ...

Growth of wild ungulate populations within protected areas can cause an expansion towards surrounding non-protected areas and lead to conflicts with human activities. The spatial and demographic structure of colonizing ...
