ECONOMIC AND SOCIO-ENVIRONMENTAL EVALUATION OF PREDATOR CONTROL ALTERNATIVES
A simulation model containing both economic (monetary) and socio-environmental (value index) components is developed in a case study of predator control alternatives. Particular emphasis is given to the description and justification of the socio-economic

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

The modeling of predator-prey interactions
, 2015 In this paper, we aim to study the interactions between the territorial animals like foxes and the rabbits. The territories for the foxes are considered to be the simple cells.

Sympatric prey responses to lethal top-predator control: predator manipulation experiments
, 2014 Introduction: Many prey species around the world are suffering declines due to a variety of interacting causes such as land use change, climate change, invasive species and novel disease.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

A Predator-Prey Model with an Application to Lake Victoria Fisheries
Greater complexity in renewable resource models is achieved by acknowledging that species interact through a predator-prey relationship in which both species are harvested.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)
The Anatomical Record, EarlyView.Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Gregarious Behaviour of Evasive Prey [PDF]
Gregarious behavior of potential prey was explained by Hamilton (1971) on the basis of risk-sharing: The probability of being picked up by a predator is small when one makes part of a large aggregate of prey.

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and
