Plant age, crop stage and surrounding habitats: their impact on sucking pests and predators complex in cotton (Gossypium hirsutum L.) field plots in arid climate at district Layyah, Punjab, Pakistan

open access: yesBrazilian Journal of Biology, 2021
Sucking pests are major threat to cotton field crop which cause unbearable losses to the crop yield. Aim of the current study was to record seasonal dynamics of major sucking insect pests including whitefly, jassid, thrips and their natural arthropod ...

Cardenolides in the defensive fluid of adult large milkweed bugs have differential potency on vertebrate and invertebrate predator Na+/K+-ATPases

open access: yesRoyal Society Open Science
Aposematic animals rely on diverse secondary metabolites for defence. Various hypotheses, such as competition, life history and multifunctionality, have been posited to explain defence variability and diversity.

Powerful proteins from polyp possessing predators [PDF]

open access: yes, 2021
Cnidarians are soft bodied animals possessing complex venom systems which have evolved to allow for the capture of arthropod and vertebrate prey, as well as to defend themselves against such predators.

Summer foraging behaviour of shallow-diving seabirds and distribution of their prey, Arctic cod (Boreogadus saida), in the Canadian Arctic [PDF]

open access: yesPolar Research, 2012
Productive areas in the Canadian Arctic seasonally provide top predators with accessible and often predictable sources of energy. Arctic cod (Boreogadus saida) aggregate in shallow bays during the summer and are exploited by seabirds and marine mammals ...

A Community-Based Conservation Initiative for Wolves in the Ladakh Trans-Himalaya, India

open access: yesFrontiers in Ecology and Evolution, 2022
We describe a pilot community-based conservation initiative for wolves Canis lupus that involves (i) voluntary deactivation of traditional trapping pits called Shandong, (ii) commitment to wildlife conservation by the local community, and (iii ...

The influence of large predators on the feeding ecology of two African mesocarnivores: the black-backed jackal and the brown hyaena

open access: yes, 2013
Interactions between apex and mesopredators and their impacts on prey populations have been well documented, while the influence of apex predators such as lions on carrion availability and the subsequent impacts at lower trophic levels are not fully ...

Aquatic macroinvertebrate responses to native and non-native predators [PDF]

open access: yes, 2014
Non-native species can profoundly affect native ecosystems through trophic interactions with native species. Native prey may respond differently to non-native versus native predators since they lack prior experience.

Camouflage in predators [PDF]

open access: yesBiological Reviews, 2020
ABSTRACTCamouflage – adaptations that prevent detection and/or recognition – is a key example of evolution by natural selection, making it a primary focus in evolutionary ecology and animal behaviour. Most work has focused on camouflage as an anti‐predator adaptation. However, predators also display specific colours, patterns and behaviours that reduce

Vertebral morphology in the tail-whipping common thresher shark, Alopias vulpinus

open access: yesRoyal Society Open Science
Thresher sharks (Alopias spp.) are characterized by an elongated, scythe-like caudal fin that is used in tail-whipping, a behaviour where the tail is thrown overhead to stun prey.

Template‐Confined Synthesis of Shape‐Engineered Single‐Crystal Gold Microplates in Lithographically‐Defined Polymeric Patterns

open access: yesAdvanced Functional Materials, EarlyView.
Single‐crystal gold microplates are high‐performance nanomaterials with an impressive wafer‐based application space. Progress has, however, been tempered by an inability to exert synthetic control over microplate size, shape, and positioning. In this work, control over these parameters is demonstrated using a seed‐mediated synthesis that both confines ...
