Mating behavior and three types of mating songs of the sandy beach-dwelling ground cricket Dianemobius csikii (Grylloidea, Trigonidiidae, Nemobiinae)

Journal of Orthoptera Research, Journal Year: 2024, Volume and Issue: 33(2), P. 249 - 254

Published: Aug. 15, 2024

This study aimed to investigate the mating behavior of sandy beach-dwelling ground cricket, Dianemobius csikii (Bolívar, 1901) (Orthoptera, Grylloidea, Trigonidiidae, Nemobiinae). The calling songs males were recorded, and temporal structures analyzed. Subsequently, courtship song cricket pairs observed. consisted only monotonous chirps, while similar chirps ticks consisting a single pulse. exhibited relatively longer duration than other species. female stayed with male for approximately 25 min emitted song. then changed trill song, which is continuous just before copulation. Copulation occurred within 10–40 s emitting differs from that well-studied species, such as Gryllinae. findings this provide insight into behaviors crickets.

Artificial light at night and temperature as combined stressors on the development, life-history, and mating behaviour of the Pacific field cricket, Teleogryllus oceanicus

Unprecedented rates of urbanisation cause detrimental impacts on the natural environment. Two most prominent and ubiquitous urban stressors are artificial light at night (ALAN) heat island (UHI) effect. Individually, these two have a wide array effects physiological, behavioural, life-history traits organisms. However, rarely work in isolation, potential interactions ALAN elevated temperatures organismal traits, particularly with respect to sexual signalling reproduction, not well understood. Here, fully factorial design, we manipulated intensities exposure (simulating pollution) and/or developmental rearing UHI effects) explore consequences for juvenile development, survival, signalling, mating behaviour Pacific field cricket, Teleogryllus oceanicus. Our data revealed significant temperature key traits. Crickets reared under had higher mortality; reduced adult longevity, altered male attractiveness. In very limited impacts, reducing development time. Similarly, both acting concert also little impact; female duration when control temperatures, but temperatures. These suggest combined this species, while consistent effects, equivocal potentially increasing fitness. highlight complexity wildlife Understanding processes is essential as predicted intensify.

Temperature and tree number drive tree crown‐dwelling arthropod diversity in Brazilian semi‐arid cities

Abstract Urbanisation is one of the most severe land use changes with significant negative impacts on several biological groups. However, response arthropods to this process still unclear, especially in cities located arid regions, which represent an important part global urban ecosystems. Here, we examined variations abundance, richness, diversity and taxonomic composition tree crown‐dwelling 10 Brazilian semiarid climate dry forest region (Caatinga), taking into account temperature gradients number street trees along cities. We expected that cooler (in a hot range temperature) more forested would present richer, abundant distinct communities than warmer This hypothesis supported by large amount evidence showing effects local structuring communities. used method arboreal arthropod collector sample community inhabiting crowns up m height. collected total 22,911 specimens belonging two classes (Insecta Arachnida) 24 orders.

Artificial light at night

Published: Dec. 26, 2024

Abstract What is artificial light pollution, and how does it affect the behaviour of animals and, in turn, populations? In this chapter, we review key literature that has framed our understanding two mechanisms by which (as an individual stressor) shifts animal behaviour: altering nocturnal photic landscape disrupting hormonal pathways drive circadian behaviour. Our highlights behavioural research field primarily focused on individual-level impacts, particularly terrestrial systems, further required landscape-level approaches to understand impact ecosystem dynamics health. Finally, highlight case studies where recent driven effective management policy mitigated at night for wildlife, resulting measurable ecological benefits.

Recent Progress in Studies on Acoustic Communication of Crickets

Published: Jan. 1, 2023

Acoustic communication between male and female crickets has been studied at both proximate ultimate levels. This chapter focuses on the study of level. The fitness benefits preference for songs have long studied. As direct benefits, there are many reported cases increased fecundity in females. an indirect benefit, it is often that offspring attractive males become sons. However, some unresolved problems exist limit our understanding acoustic crickets, including relationships with other sexually dimorphic traits such as weapon influence conspecific social communication. For example, owing to aggressiveness socially isolated toward females, reproductive success hindered. Furthermore, signals can be used cues by heterospecific individuals. Predators parasitoids eavesdrop locate attack them. Moreover, song one cricket species may interfere (acoustic masking interference). Finally, I explore how anthropogenic disturbances impact

Multiple carotenoid-based signals are enhanced despite poor body condition in urban male and female Northern Cardinals (Cardinalis cardinalis)

ABSTRACT If humans aim to sustainably coexist with wildlife, we must understand how our activity impacts the communication systems of urban animal populations. We know much about effects anthropogenic noise on bird song, but relatively little avian visual signals are affected by urbanization. One way such an effect may occur if urbanization alters food available species color based carotenoids, which they obtain from their diet. Over three years, compared a comprehensive suite in male and female Northern Cardinals ( Cardinalis cardinals ) rural population. predicted that birds would have enhanced carotenoid-based as likely access more carotenoids invasive plants, especially honeysuckle Lonicera spp.), thrive cities. used reflectance spectrometry, digital image analyses, models quantify hue, saturation, brightness chest (male), underwing (female), bill (male female) signals. Compared males, males had redder feathers one year bills every year. Urban females saturated than These differences were sufficient be distinguished system. Urbanization did not affect color. Interestingly, significantly reduced mass-related body condition birds. results show both can display despite being poor condition.
