Abstract:
... On 10 March 2014, a radio‐tracked Australian scrub python (Simalia amethistina) made a predatory attack on a 64 kg sleeping woman. The snake was unsuccessful, but data from our radio‐tracking programme suggest that predation attempts on oversized prey are not uncommon – even if they threaten the survival of the predator. We explore hypotheses about why snakes attempt to consume such large meals. ...

Abstract:
... In this paper, we present and analyze a spatio-temporal eco-epidemiological model of a prey predator system where prey population is infected with a disease. The prey population is divided into two categories, susceptible and infected. The susceptible prey is assumed to grow logistically in the absence of disease and predation. The predator population follows the modified Leslie-Gower dynamics and ...

Abstract:
... Many researchers highlight the role of urban ecology in a rapidly urbanizing world. Despite the ecological and conservation implications relating to carnivores in cities, our general understanding of their potential role in urban food webs lacks synthesis. In this paper, we reviewed the scientific literature on urban carnivores with the aim of identifying major biases in this topic of research. In ...

Abstract:
... Animal movements are highly constrained by morphology and energetics. In addition, predictable bodily damage can constrain locomotion even further. For example, for animals moving on land, losing legs may impose additional costs. We tested if losing legs affects the distance travelled over time (endurance) and the metabolic costs of locomotion (oxygen consumption) in Nelima paessleri harvestmen. T ...

Abstract:
... The effects of human disturbance spread over virtually all ecosystems and ecological communities on Earth. In this review, we focus on the effects of human disturbance on terrestrial apex predators. We summarize their ecological role in nature and how they respond to different sources of human disturbance. Apex predators control their prey and smaller predators numerically and via behavioral chang ...

Abstract:
... Grouping behaviour displayed by animals is usually attributed to predation and foraging‐related benefits. The mechanisms of predator protection and foraging efficiency are diverse and often produce conflicting drivers of grouping behaviour. One key conflict is that between group size and phenotypic oddity. Theoretically, individuals should choose the largest available group due to multiple mechani ...

Abstract:
... Sexual size dimorphism (SSD), commonly observed in snakes, may arise from a different growth rate between the sexes. This indicates a sex-specific resource intake that is in fact observable in free-living snakes. It is not so well known whether the sexes can express differential feeding rates under conditions unconstrained by spatial accessibility, competition, etc. Here, I studied sex-specific va ...

Abstract:
... Understanding how predators affect prey populations is a fundamental goal for ecologists and wildlife managers. A well‐known example of regulation by predators is the predator pit, where two alternative stable states exist and prey can be held at a low density equilibrium by predation if they are unable to pass the threshold needed to attain a high density equilibrium. While empirical evidence for ...

Abstract:
... Animal behaviours often dependent on age. In many insect species, walking shows an age-dependent decline, and food intake may also be dependent on age. However, few studies have investigated the relationship between age and walking or food intake.

Abstract:
... Small-scale spatial variability can affect community dynamics in many ecological and biological processes, such as predator-prey dynamics and immune responses. Spatial variability includes short-range neighbour-dependent interactions and small-scale spatial structure, such as clustering where individuals aggregate together, and segregation where individuals are spaced apart from one another. Yet, ...

Abstract:
... In consumer communities, intra‐guild predation (IGP) is a commonly observed interaction that is widely believed to increase resource density. However, some recent theoretical work predicts that resource density should first decrease, and then increase as the strength of IGP increases. This occurs because weak to intermediate IGP increases the IG predator density more than it reduces the IG prey de ...

Abstract:
... The frequency and unpredictability of predator attacks can substantially influence vigilance patterns in prey animals. However, the lack of control over predator behavior hampers our understanding of the effect of predator attack patterns on vigilance. To circumvent this limitation, I developed a virtual experiment in which the behavior of the (virtual) predator was under full control of the exper ...

BACKGROUND: With the increase in telemetry studies over the past decade, improving understanding of how different tagging methods influence the probability of presence in a receiver array is important in maximizing the resulting data. Disappearance from the array may be due to mortality from surgery complications, tag loss, predation, or emigration. Internally tagging fish on a boat can cause baro ...

Abstract:
... Predatory interactions among anurans (Lissamphibia; Order: Anura) within food webs are important to assessing mortality threats in a conservation context. Anurans are a significant prey item for other anurans in post-metamorphic stage; however, to date, there are few studies addressing the distribution of frog-eat-frog predatory behavior across anuran taxa. Therefore, in this work, we review frog- ...

Abstract:
... In cooperatively breeding species, subordinates forgo reproduction to assist breeders in raising offspring. When cooperative breeding is facultative, breeders from the same population may differ in whether they are assisted by non‐breeding helpers. Predation risk is a major source of nest failure and assistance during nest defense is often an overlooked, yet important, way helpers assist breeders. ...

Abstract:
... Predation often deviates from the law of mass action: many micro‐ and meso‐scale experiments have shown that consumption saturates with resource abundance, and decreases due to interference between consumers. But does this observation hold at macro‐ecological scales, spanning many species and orders of magnitude in biomass? If so, what are its consequences for large‐scale ecological patterns and d ...

Abstract:
... Camouflage through background matching is a widespread antipredator strategy in which animals blend in with their background to avoid detection. To maximise survival in a variable natural environment, animals can have colourations that either match one of the backgrounds maximally (i.e. specialist strategy) or match multiple backgrounds partially (i.e. generalist strategy).
