Wildlife Management in the Presence of Predation and Damage Costs.

Publication Type: Academic Journal

Source(s): Journal of Forest Economics. 2022, Vol. 37 Issue 4, p437-454. 18p.

Authors:

Abstract: In this paper a simple age-structured model is constructed to analyze how a wildlife population creating hunting value, but also damage costs, is influenced by predation. The model may exemplify a moose population causing forest browsing damage and exp...

Concealed Object Detection.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Pattern Analysis & Machine Intelligence. Oct2022, Vol. 44 Issue 10, p6024-6042. 19p.

Abstract: We present the first systematic study on concealed object detection (COD), which aims to identify objects that are visually embedded in their background. The high intrinsic similarities between the concealed objects and their background make COD far mo...

The persistence and bifurcation analysis of an ecological model with fear effect involving prey refuge and harvesting.

Publication Type: Conference

Source(s): AIP Conference Proceedings. 2022, Vol. 2394 Issue 1, p1-17. 17p.

Abstract: In this work, the sufficient conditions for uniformly persistence of a food chain prey-predator model with prey refuge and harvesting have been found. By creating suitable Lyapunov functions, a set of sufficient conditions that can be checked easily ar...

Analytical study of delayed prey–predator system in aquatic world.

Publication Type: Conference

Source(s): AIP Conference Proceedings. 11/8/2022, Vol. 2481 Issue 1, p1-9. 9p.

Abstract: In this paper, a delayed prey–predator system, where both prey and predator exhibit schooling behavior, is discussed. We examine the effect of time delay on the predation term of the prey–predator system. By choosing τ a discrete-time delay as a bifurc...

Accounting for predator species identity reveals variable relationships between nest predation rate and habitat in a temperate forest songbird.

Publication Type: Academic Journal

Source(s): Ecology & Evolution (20457758). Oct2022, Vol. 12 Issue 10, p1-10. 10p.

Abstract: Nest predation is the primary cause of nest failure in most ground‐nesting bird species. Investigations of relationships between nest predation rate and habitat usually pool different predator species. However, such relationships likely depend on the s...

Predation‐mediated edge effects reduce survival of wader nests at a wet grassland‐forest edge.

Publication Type: Academic Journal

Source(s): Animal Conservation. Oct2022, Vol. 25 Issue 5, p692-703. 12p.

Abstract: Edge effects occur when the matrix has adverse impacts on the patches of remnant habitat. A widely explored example of this is the hypothesis of a higher predation pressure on bird nests closer to the habitat edge. In parallel with the recent loss of o...

Amazon: A story of accumulation through intellectual rentiership and predation.

Publication Type: Academic Journal

Source(s): Competition & Change. Jul2022, Vol. 26 Issue 3/4, p436-466. 31p.

Authors:

Abstract: This article elaborates on intellectual monopoly theory as a form of predation and rentiership using Amazon as a case study. By analysing Amazon's financial statements, scientific publications and patents, we show that Amazon's economic power heavily r...

Using referential alarm signals to remotely quantify 'landscapes of fear' in fragmented woodland.

Publication Type: Academic Journal

Source(s): Bioacoustics. Dec2022, Vol. 31 Issue 6, p629-645. 17p.

Abstract: Land-use changes have greatly impacted biodiversity and led to new conservation challenges, including greater predation pressure, although this can be difficult to quantify. Here we directly monitor predator encounters in fragmented woodlands by using ...

Background matching explains repeatable individual variation in the defence strategies of a stick insect.

Publication Type: Academic Journal

Source(s): Animal Behaviour. Dec2022, Vol. 194, p185-192. 8p.

Abstract: Visually matching the background environment is an important means by which many animals avoid predation. Yet natural habitats are rarely uniform over space and time. A key question is whether prey behaviour depends on an individual's perceived vulnera...

Predator-induced transgenerational plasticity in animals: a meta-analysis.

Publication Type: Academic Journal

Source(s): Oecologia. Dec2022, Vol. 200 Issue 3/4, p371-383. 13p. 3 Diagrams, 3 Charts.

Abstract: There is growing evidence that the environment experienced by one generation can influence phenotypes in the next generation via transgenerational plasticity (TGP). One of the best-studied examples of TGP in animals is predator-induced transgenerationa...
