Fig. 1 in Biology and Conservation of Cicindela ohlone Freitag and Kavanaugh (Coleoptera: Carabidae: Cicindelinae), the Endangered Ohlone Tiger Beetle. II. Population Ecology of Adults and Larvae and Recommended Monitoring Methods
Fig. 1. Marking scheme for individual identification of Ohlone tiger beetle adults used during the capturerecapture and frequency of capture studies. Some variation in the maculations exists. Numbers on the elytra represent the positions for marking each beetle with a unique identification number. Marks applied to single or multiple locations uniquely identify each marked beetle. For example, beetle #1 would have a mark at the #1 position, beetle #12 would have marks at the #2 and #10 locations, and beetle #147 would have marks at the #7, #40, and #100 locations.

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>
