“…We also found that local density influenced cooing activity, with birds being less vocally active when fewer than three males were singing simultaneously (Figure 1). A similar pattern was also observed by Gutiérrez-Galán (2016), who found that the average duration of silence between singing bouts was longer for densities of less than three singing males than for males at higher densities. Social stimulation of singing, with more intense singing activity in the presence of other singing males, has been also observed in other species (Sexton et al, 2007;Alldredge et al, 2007b;Voigt et al, 2021).…”

“…For example, Calladine et al (1999) mentioned lower cooing activity in late June than mid-June or early July, and Gutiérrez-Galán (2016) observed a drop in cooing rates in the second fortnight of May. These variations could be associated with periods of unusually poor weather, which could limit cooing activity, as suggested by Gutiérrez-Galán (2016). Our study, based on intensive monitoring throughout the breeding season in three years and across four distinct study areas, and which avoided days of very poor weather for surveys, did not show a drop in cooing activity during the breeding season.…”

“…Calladine et al, 1999;Dias et al, 2013;Gutiérrez-Galán et al, 2018;Chiatante et al, 2021), since males of this species perform their characteristic coos as territorial song. It has been previously shown that male cooing activity varies throughout the breeding period and in relation to time of day (Calladine et al, 1999;Rocha & Hidalgo de Trucios, 2002;Gutiérrez-Galán, 2016), although detailed parametrisation of these variations is not readily available. A previous study has also suggested that survey duration should be at least ten minutes in order to minimise the likelihood of missing males between cooing bouts (Gutiérrez-Galán, 2016), but there is no information about whether this is valid in all contexts or regarding the relationship between detectability and survey duration.…”

SummarySurveys based on abundance indices may still be the most cost-efficient method for monitoring programmes that aim to be extensive in time or space, but it is important to take into account differences in activity patterns when combining data collected at different times or from different areas. The European Turtle-dove Streptopelia turtur is a migratory game species that has declined in recent decades and for which identifying efficient and easy-to-apply monitoring schemes to assess changes in abundance is critical for adaptive management. We describe variation in cooing activity to help optimising Turtle Dove abundance monitoring schemes based on point-counts of cooing males. Cooing activity (number of minutes during a ten-minute sampling period when each Turtle Dove was cooing) declined markedly and linearly throughout the morning; in addition, it increased slightly from May to late June, and declined abruptly in the second half of July. The number of different turtle doves detected per ten-minute period significantly declined with time since dawn and was markedly lower after mid-July. Predicted abundance per observation point at dawn on 25 June (from a GLM per region including time and a quadratic relationship with date), correlated tightly (r = 0.95) with the average number of turtle doves detected at each point over multiple visits during the breeding season. Correlation of the latter with the number of birds observed in a single visit during the breeding period was weaker (0.68 ± 0.02). Estimated abundance per point was higher the longer the monitoring bout duration, but five-minute periods allowed detecting c. 80% of birds detected during ten-minute periods. To optimize Turtle Dove abundance monitoring schemes based on abundance indices, we suggest implementing five-minute samplings from mid-May to mid-July during the first three hours after dawn, and transforming the observed values into predicted values considering the date and time at which surveys were made, to obtain comparable results across observation points and years.—Arroyo, B., Moreno-Zarate, L., Fernández-Tizón, M., Sardà-Palomera, F., Bota, G. & Mougeot, F.

“…The duration of food provision was similar during the study period (median: 85 days), but the amount provided per plot increased from 800 kg in 2009 to 2600 kg in recent years. This may be attributed to the hunting interest in turtle doves and other columbids in this part of Spain, the lack of natural food experienced in the last decade, caused by changes in agriculture [ 38 ] or lack of management of forested areas which may result in low availability of natural habitats in which turtle doves find seeds [ 39 ]. In some cases, food provision is the only way to provide food due to the difficulties in creating seed-rich habitats (such as uncultivated plots and game crops) [ 12 ].…”

In some regions of Spain, hunting grounds conduct management targeting the European turtle dove (Streptopelia turtur), a commonly hunted species, and unsustainable harvesting levels at these sites have been identified as one of the factors responsible for the species’ decline across its range. In hunting grounds where food was provided, we estimated the local turtle dove abundance before the hunting season, productivity (juvenile/adult ratio) and harvesting levels using harvest data from managed grounds over 4 years (2009, 2015, 2019 and 2020). Compared to previous research, a higher productivity value was found (median 1.67, range 1.24–4.15) in grounds providing more food for a longer period. We calculated that the harvesting rate should not exceed 37% of the estimated turtle dove population size (35–45%). Significant differences were found between the estimated local turtle dove abundance using a removal sampling protocol and the number of birds observed by hunters before the hunting season, which suggests that in a high proportion of grounds, the latter method may have led to bird overestimation and overharvesting. Our research supports the current European Union’s harvest management plan to promote sustainable hunting in grounds where targeted management is conducted.

Litterfall production plays a fundamental role in the dynamics and function of tropical forest ecosystems, as it supplies 70–80% of nutrients entering the soil. This process varies annually and seasonally, depending on multiple environmental factors. However, few studies spanning several years have addressed the combined effect of climate variables, successional age, topography, and vegetation structure in tropical dry forests. In this study, we evaluated monthly, seasonal, and annual litterfall production over a five-year period in semideciduous dry forests of different successional ages growing on contrasting topographic conditions (sloping or flat terrain) in Yucatan, Mexico. Its relationship with climate and vegetation structural variables were also analyzed using multiple linear regression and generalized linear models. Litterfall was measured monthly in 12 litterfall traps of 0.5 m2 in three sampling clusters (sets of four 400 m2 sampling plots) established in forests of five successional age classes, 3–5, 10–17, 18–25, 60–79, and >80 years (in the latter two classes either on slopping or on flat terrain), for a total of 15 sampling clusters and 180 litterfall traps. Litterfall production varied between years (negatively correlated with precipitation), seasons (positively correlated with wind speed and maximum temperature), and months (negatively correlated with relative humidity) and was higher in flat than in sloping sites. Litterfall production also increased with successional age until 18–25 years after abandonment, when it attained values similar to those of mature forests. It was positively correlated with the aboveground biomass of deciduous species but negatively correlated with the basal area of evergreen species. Our results show a rapid recovery of litterfall production with successional age of these forests, which may increase with climate changes such as less precipitation, higher temperatures, and higher incidence of hurricanes.
