“…While this finding in fisheries science indicates that selective capture can indirectly contribute to damage mitigation through microevolution (Diaz Pauli and Sih 2017), the methodology for selective capture of mammals should be clarified. Recent studies have suggested that the most effective method is the hunting/culling of animals in farmlands and around forest edges (Thurfjell et al 2009; Honda et al 2014; Honda and Iijima 2016; Hinton et al 2020) because individuals that use the farmland often use the forest edge (Baasch et al 2010; DeVore et al 2016; Found and St Clair 2019). A theoretical explanation for why farmland-utilizing individuals are less likely to use deep forests is that the cost of moving to deep forests is high (Baasch et al 2010); this fact is supported by an empirical study using radio telemetry (Honda et al 2008).…”

“…In Canada, there is no evidence that increase in harvesting practices lead to reduction in human–bear conflicts (Obbard et al 2014). In Japan, the population growth ratio of sika deer and the damage increase ratio do not coincide (Honda et al 2014). Damage to northern temperate forests caused by Cervidae is associated with the density of Cervidae (Gill 1992).…”

Why Mammals do Not Damage Entire Farmlands Like Insect Pests Do? A Review from a Behavioral Perspective

Crop damage caused by mammals is not uniformly distributed and is more localized near the forest; this damage distribution differs from that of insect pests. Species that cause damage are often forest inhabitants and hence the damage sites are also biased toward the forest edge. However, these species do not necessarily use forests as their home ranges for cover or shelter, but may be entirely urban (e.g., urban bears). Forest vegetation cannot be considered essential for these species, as this contradicts the behavior of animals that use urbanized areas only. Our review illustrates why crop damage is uneven, localized at forest edges, and less likely to occur on farmlands away from forests in terms of population density, food availability, personality, habituation, and human behavior. This review reveals the role and risk perception of human disturbances. If risk of farmland is perceived to be greater than the true risk, mammals prefer farmlands near forests with low degrees of human disturbances (perceptual trap). The current damage distribution is a result of this perceptual trap because hunting pressures are not always higher in farmlands than in forests.

“…The difference is likely related to specifics in the aetiology and ecological preferences of the non-native, originally East Asian sika deer, and European red deer. Sika deer favours open land habitats that are more likely to have lower mosquito populations (Honda et al ., 2014; Macháček et al ., 2014). Setaria cervi has rarely been reported in sika deer from Europe (Rehbein and Visser, 2007).…”

Setaria cervi(Filarioidea, Onchocercidae) undressing in ungulates: altered morphology of developmental stages, their molecular detection and complete sequencecox1 gene

This work introduces new morphological and molecular information on the filaroid nematode Setaria cervi (Rudolphi, 1819) obtained from 13 infected game ungulates out of 96 dissected. The hosts comprised the following: a single moose (Alces alces), ten red deer (Cervus elaphus) and two sika deer (Cervus nippon) originating from the western and northern regions of the Czech Republic. Based on the complete sequences of the gene encoding mitochondrial cytochrome c oxidase subunit 1 (cox1), all 20 females and four males belonged to the species S. cervi. We detected three developmental female stages (adult fertile females, juvenile L5 females and L4 female larvae) differing in size and some morphological traits as the subtle structure of peribuccal crown and shape and features of tail knob. Such differences were described in detail for the first time. The phylogenetic relationships within the family Onchocercidae have been evaluated using new information on the cox1 sequence of S. cervi (maximum likelihood method, GTR + I + G model). In accordance with the latest phylogenetic studies, the present analysis confirmed the ancient separation of the subclass Setariinae from the remaining two onchocercid lineages Dirofilariinae and Onchocerinae.

Managing boldness of wildlife: an ethological approach to reducing crop damage

Wildlife can cause serious crop damages, and factorial analyses focusing ecological aspects have been conducted to resolve this problem. However, ethological perspectives should also be considered. Individuals often show consistent biases in behaviour—so‐called personality; e.g., boldness may cause to intrude into a farmland. Here, we hypothesized that boldness–shyness traits in wildlife could be managed through selective harvesting on the base of personality traits. We considered several scenarios involving the selective harvesting and fencing as means to prevent crop damage, and assessed their effects on the average boldness and population size using simulation models, assuming that bold individuals tend to enter farmlands, while shy ones prefer to stay in forests. The results showed that fencing and selective harvesting in farmlands reduced both the average boldness and crop damages, while harvesting in forests caused the increase of the both. Those results came from the selective harvesting and fencing on the base of personality traits, and indicate that not only population ecology but also an ethological approach is needed for wildlife management.
