AB - Risk taking behaviour — how individuals perceive and respond to threat — varies among individuals. In birds, this behaviour influences the choice of nest microhabitat presumably because exposure to predation depends on the structural composition of the nest microhabitat (i.e., a small area where a bird builds its nest). Thus, a chosen nest microhabitat can indicate an adaptation to predation risk. However, where both parents participate in or share breeding roles, it is unknown whether the chosen nest microhabitat is influenced by risk taking behaviour of the female, the male or both parents. Moreover, risk taking may affect other behaviours during breeding, thus having a partner with similar risk taking behaviour may be important for pair complementarity. We investigated risk taking behaviour of breeding Kentish plovers (Charadrius alexandrinus) using flight initiation distance (FID) as a proxy. First, we tested whether FID is repeatable. Second, we tested whether members of breeding pairs have similar FID. Third, we investigated whether male and female’s FID is associated with the choice of nest microhabitat. We classified nest microhabitat by two indices: cover directly above the nest scrape (above nest cover) and cover around the nest (around nest coverage). We found that (i) FID was highly repeatable, (ii) FID was correlated within members of breeding pairs and (iii) female’s risk taking behaviour is linked to the use of around nest coverage. Specifically, females with longer FID, (i.e., more risk-averse ones) tended to use less concealed nest microhabitat. We concluded that nest microhabitat choice in the Kentish plovers is likely a reflection of the female’s risk taking behaviour. Breeding partners likely have similar risk taking behaviour, an indication of assortative mating. We advocate partitioning of correlation within breeding pairs to ascertain estimates of within pair correlation attributable to assortative mating. © 2024 Brill Academic Publishers.

The wildlife on islands are particularly vulnerable to threats posed by alien predators, habitat loss and overexploitation. Effective conservation management of vulnerable species requires reliable information on vital population rates for all life stages and an understanding of key environmental drivers. However, demographic data are often not available for island populations before they decline or are extirpated. Here, we use Cormack–Jolly–Seber (CJS) models and 15 years of data for 1370 juveniles and 687 adults to estimate apparent survival for a genetically distinct resident population of Kentish plovers Charadrius alexandrinus on the island of Maio, Cabo Verde. We report two main findings. First, environmental conditions have a large effect on demographic performance since chicks that hatch during dry years experience a tenfold reduction in first-year survival compared to chicks that hatch during wet years. Second, female and male plovers in Maio are expected to live for 7.41 ± 0.69 (mean ± SE) years and 6.75 ± 0.64 years, respectively, due to relatively high annual survival among comparable-sized shorebirds. High adult survival thus could buffer the population against low reproductive success that this population has experienced over the last decade. Cabo Verde is typical of tropical islands with increased development that can impact native breeders and/or will accelerate habitat loss. Thus, more frequent droughts associated with climate change may exacerbate the prospects of native wildlife on many islands. © 2024 The Authors.

AB - Although biparental care is thought to be rare among insects, it has evolved independently numerous times resulting in diverse forms and varying levels of parental involvement. Several theoretical studies address potential factors promoting biparental care in beetles; however, empirical studies target principally only species of Scarabaeidae and Silphidae families. Here, we investigated the behavioural repertoire of the breeding pairs in two natural populations of a geotrupid beetle Lethrus apterus with parental care. Changes in female care as a response to the male’s absence were also investigated by experimentally removing males from pairs. We found that males spend the majority of their time at the nest entrance, while females leave their nest and collect leaves at a significantly higher rate than males. We also showed that males often desert their nests and were usually replaced by new males in a short time. The desertion of males, however, does not seem to influence females’ behaviour. These findings indicate that L. apterus may have a dynamic mating system with typically short-term mate fidelity. Furthermore, our results have advanced our understanding of parental roles and nesting behaviour and contributed to the description of the distinct roles of parents in different phases of nesting events in L. apterus beetles.

The costs and benefits of care are key to understanding patterns of parental care, where parents can benefit by having their partner increase investment in care, while reducing their own effort. However, investigating the costs and benefits of parental care in wild populations is challenging. Here we use highly detailed behavioral observations in families of a small shorebird, where one parent frequently deserts its offspring, to explore the potential costs and benefits of desertion in a wild population. We first show that females desert their broods more frequently than males. Second, we investigate the benefits of this frequent female desertion in terms of additional mating opportunities, and the costs of desertion to females in terms of the growth and survival of deserted offspring. Our results indicate that female desertion is favored by a combination of remating benefits and a lack of costs to brood growth and survival, as abandoned male parents continue to provide care after desertion. Our results shed light on the costs and benefits underlying natural desertion strategies and suggest that female desertion is a fine-tuned behavior that responds to seasonally changing benefits of desertion. © The Author(s) 2022.

Species in the family Jacanidae are commonly used for studying this type of breeding system (called sex-role reversal), and previous studies found discrepancies and variation between species in the expected characteristics of reversed sex roles. Yet, a better understanding of sex role differences in breeding behavior in such species is crucial for disentangling possible evolutionary mechanisms leading to this peculiar breeding system. Sex-role reversal in the pheasant-tailed jacana Hydrophasianus chirurgus has been documented long time ago. Since the very early observation of this species, however, there was no attempt to provide a comprehensive and quantitative description of their breeding. This study aims to fill these knowledge gaps by investigating the sex role differences in the breeding behavior of pheasant-tailed jacanas, by observing and monitoring a breeding population in Taiwan. We focused on three main characteristics of sex-role reversal: (1) competition between females for access to males, such as agonistic and courtship behaviors, (2) polyandrous mating, and (3) male-only care. As expected, we found that females provide most of the territory defense toward conspecifics. Males also participated in agonistic behaviors, although less frequently than females. Furthermore, contrary to what was expected, we found that males spent more time than females on courtship behavior. Polyandrous females performed mating and laying sequentially with different mates but maintained the pair bonds simultaneously with multiple males. For the first time for the species, we could estimate that the average number of mates per female (i.e., degree of polyandry) was 2.4 and that at least 81.8% of the females in the population were polyandrous. Finally, our observations corroborated that brood care is predominantly provided by males, nevertheless females were also participating to some degree in brood attendance but never in direct care (i.e., brooding). This study highlights that some aspects of polyandrous breeding might deviate from stereotyped view on sex-role reversal, and stress the importance of further within species and comparative studies in order to fully understand the mechanisms leading to sex-role reversal.

AB - Several members of the highly conserved oxytocin/vasopressin neuropeptide family are involved in the regulation of reproductive and affiliative behaviours in numerous vertebrate and invertebrate species. Here we investigate gene expression patterns of inotocin, the insect ortholog of this peptide family, and its receptor to decipher their possible role in the control of reproductive behaviour in a beetle, Lethrus apterus, with biparental care. In an experiment performed on individuals of a wild population, we found that inotocin is not related to the control of water balance in this species because expression patterns did not change as a response to drought exposure. The expression levels of inotocin and its receptor, however, increased over the reproductive season i.e., when behaviour shifts from pair formation to parental care, suggesting that inotocin might be involved in the regulation of parental care in this insect. No difference was, however, found between sexes; a finding which might indicate that inotocin plays a similar role in both parents. LA - English DB - MTMT ER - TY - JOUR AU - Yilmaz, K.

AB - Within this study, bird species composition, spatial distribution of nests of the most common breeding bird species-the Kentish plover (Charadrius alexandrinus L.)-coastal habitat types, and spatiotemporal change on lagoon surface area were monitored. Field work and water-level monitoring occurred during a 2-year period form 2009 to 2011. Habitat mapping was accomplished through a combination of remote sensing (unsupervised classification of vegetation types) combined with ground truthing. Eleven habitat types were mapped in GIS software to create a dynamic habitat map for analyzing distribution and abundance of waterfowl. Annual changes in water levels and its effect on adjacent habitats are explored. Fifty-two nests were located in 2009 on places that were inundated by the spring flood and were, thus, potentially endangered by the flood. For change detection of the wetland, 13 Landsat Thematic Mapper and Enhanced Thematic Mapper Plus scenes, covering the period between January 2009 and October 2009, were used for pair-wise comparisons. For land cover classification, a WorldView-2 data was used and the information obtained was used in delineating boundaries of habitats. During the point surveys at the six observation points, 44 bird species were observed, whereas 65 bird species in total were recorded in the course of the project. At the salt marshes, 36 species were recorded, whereas at the freshwater marsh habitat, there were 28 species. In total, 247 Kentish plover nests were found during 2 years. The date eggs were laid was known for 198 nests; most nests were laid during May. The overall objective of this article was to develop a monitoring methodology for predicting the effect of inundation on reproductive success, understanding the habitat features of nesting waterfowl species, and estimating their population size for future monitoring of coastal wetlands.
