Predator-prey overlap induced Holling type III functionalresponse in the North Sea fish assemblage

open access: yes, 2009
No abstracts are to be cited without prior reference to the author.Understanding the response of predator populations to varying prey fields is a prerequisite to understand prey population dynamics and to correctly parameterise multi species stock ...

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

PREDATOR-PREY SYSTEMS IN PEST MANAGEMENT [PDF]

open access: yes
The use of chemical pesticides frequently causes minor pests to become serious problems by disturbing the natural controls that keep them in check. As a result, it is possible to suffer heavier crop losses after pesticides are introduced than before ...

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

The musculature and skeleton of the pelvic fin of the crocodile shark, Pseudocarcharias kamoharai (Matsubara, 1936) (Elasmobranchii: Lamniformes): Morphology and sexual dimorphism

open access: yesThe Anatomical Record, EarlyView.
This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...
