Low reproductive success of the endangered Iberá Seedeater in its only known breeding site, the Iberá Wetlands, Argentina
<div class="page"> <div class="section"> <div class="layoutArea"> <div class="column"> <p>Subtropical grasslands are highly susceptible to habitat conversion and number among South America's most threatened ecosystems. The grasslands of northeastern Argentina have been identified as a priority conservation area for threatened capuchino seedeaters because they constitute the main breeding area of these migratory birds. The Iberá Seedeater (<em>Sporophila iberaensis</em>) is a newly described species in the Iberá Wetlands in Argentina whose biology is still poorly understood. The endangered species inhabits grasslands, but has only been reported to breed in the Iberá Wetlands ecoregion of northeastern Argentina. To explore the species' association with grassland vegetation, we studied the breeding biology (clutch size, hatching success, and fledgling production) of the Iberá Seedeater and the main parameters that influence nest survival and nest site selection. We conducted nest searches and banded adults and nestlings in Iberá National Park during the breeding seasons of 2016-2018. The breeding season of the Iberá Seedeater was highly synchronous and the cumulative probability of nest survival was 0.16. The daily nest survival rate decreased as the breeding season advanced, survival was lower for nests supported by <em>Rhynchospora corymbosa</em> than <em>Paspalum durifolium</em>, the two main nest substrates, and the main causes of nest failure were nest predation and strong winds. Additionally, the population exhibited male-biased site fidelity and a low female return rate. In contrast to other capuchinos, whose breeding biology is associated with upland grasslands, the Iberá Seedeater nested exclusively in flooded lowland grasslands on marsh plants. Thus, effective lowland grassland management is key to maintain the vegetation structure required for reproduction in the Iberá Seedeater.</p> </div> </div> </div> </div>

Behavioural syndrome between boldness and aggressiveness and link with reproductive success in a wild bird population
<p>Boldness, defined as the behavioural response of individuals when facing a risky situation, is a major personality trait and often phenotypically correlates with other behavioural traits, in particular aggressiveness, exploration behaviour and neophobia. Yet, whether such links result from among-individual correlations, i.e. form behavioural syndromes sensu stricto, is often ignored and whether such syndromes may yield individual fitness benefits, and thus be selected for, remains poorly explored. We measured boldness as the nest defence behaviour against a dummy nest predator in a natural population of a small passerine bird, the collared flycatcher, <em>Ficedula albicollis</em>, and investigated the existence of a behavioural syndrome between boldness and two other behavioural traits, aggressiveness (measured as the agonistic response to competitors) and neophobia (measured as the behavioural response to a novel object in a known environment). Then we assessed the links between this potential syndrome and reproductive success, measured as fledging and recruitment success. Boldness score differed between the sexes and depended on whether the partner was present during the test. Nevertheless, it was repeatable, showing that boldness can be considered as a personality trait in our population. We found a positive among-individual correlation between boldness and aggressiveness, showing the existence of a behavioural syndrome between both personality traits. This syndrome was related to reproductive success: the number of fledged young (but not recruitment probability) increased with one integrative value of the boldness–aggressiveness syndrome. Conversely, boldness score was not correlated with neophobia. Our results thus clearly reveal a behavioural syndrome between boldness and aggressiveness with possible consequences for reproductive success in the study population, and therefore raise the question of the evolutionary implications of such a behavioural syndrome.</p>

FIGURE 2. Kalanchoe ×sampsonii. A. At flowering maturity plants of this shrubby nothospecies reach a height of about 0.5 m. B. Through heterosis, inflorescences are more branched and have a wider spread than in either of the parents. C. Peduncles are more intensely reddish-infused than in K. ×hankeyi, but less than in K. sexangularis. D. Flowers (corolla tube and corolla lobes) are more intensely yellow than those of either of the parents. E. Flowers, here in lateral view, of K. ×sampsonii (centre) are often intermediate between those of K. longiflora (left, one of the parents of K. ×hankeyi) and K. sexangularis (right), but the corolla tube is more intensely yellow. F. Corolla lobes of K. ×sampsonii (centre) are more intensely yellow than those of K. longiflora (left, one of the parents of K. ×hankeyi) and K. sexangularis (right, the other parent of K. ×hankeyi).

FIGURE 1. Kalanchoe ×hankeyi (A–B) and K. sexangularis (C–D). A. Leaves of K. ×hankeyi are light green to strongly red-infused, especially when grown in full sun. The marginal leaf crenations of K. ×hankeyi are situated more towards the upper parts of the leaf margins, as in one of its parents, K. longiflora, rather than virtually along the whole margin, as is found in the other parent, K. sexangularis. B. Flowers of K. ×hankeyi have yellow corolla lobes and a greenish yellow tube. C. Leaves of K. sexangularis turn a bright crimson red when exposed to high levels of solar irradiation. D. As in the case of K. ×hankeyi, flowers of K. sexangularis have a greenish yellow corolla tube and yellow corolla lobes. All photographs taken by Gideon F. Smith.
