Abstract The population of the recently-described Whenua Hou diving petrel Pelecanoides whenuahouensis comprises c. 200 adults that all breed in a single 0.018 km2 colony in a dune system vulnerable to erosion. The species would therefore benefit from the establishment of a second breeding population through a translocation. However, given the small size of the source population, it is essential that translocations are informed by carefully targeted monitoring data. We therefore modelled nest survival at the remaining population in relation to potential drivers (distance to sea and burrow density of conspecifics and a competitor) across three breeding seasons with varying climatic conditions as a result of the southern oscillation cycle. We also documented breeding phenology and burrow attendance, and measured chicks, to generate growth curves. We estimated egg survival at 0.686, chick survival at 0.890, overall nest survival at 0.612, and found no indication that nest survival was affected by distance to sea or burrow density. Whenua Hou diving petrels laid eggs in mid October, eggs hatched in late November, and chicks fledged in mid January at c. 86% of adult weight. Burrow attendance (i.e. feeds) decreased from 0.94 to 0.65 visits per night as chicks approached fledging. Nest survival and breeding biology were largely consistent among years despite variation in climate. Nest survival estimates will facilitate predictions about future population trends and suitability of prospective translocation sites. Knowledge of breeding phenology will inform the timing of collection of live chicks for translocation, and patterns of burrow attendance combined with growth curves will structure hand-rearing protocols.

Abstract 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 (Sporophila iberaensis) 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 Rhynchospora corymbosa than Paspalum durifolium, 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.

Compensation Hypothesis

ABSTRACTThe Functional Compensation Hypothesis (Hochberg 1986a, b) interprets frequent expression of pronominal subjects as compensation for frequent deletion of agreement marking on finite verbs in Puerto Rican Spanish (PRS). Specifically, this applies to 2sg.túwhere variably deleted word-final -smarks agreement. If the hypothesis is correct, finite verbs with agreement deleted in speech should co-occur more frequently with pronominal subjects than finite verbs with agreement intact. Likewise, social dialects which frequently delete agreement should show higher rates of pronominal expression than social dialects which less frequently delete agreement. These auxiliary hypotheses are tested across a socially stratified sample of 62 speakers from San Juan. Functional compensation does show stylistic and social patterning in the category of Specifictú, not in that of Non-specifictú. However, Non-specifictúis the key to frequency differences between -s-deleting PRS and -s-conserving Madrid; hence the Functional Compensation Hypothesis should be discarded.

Abstract Objective: This study aimed to examine factors that may have contributed to community disaster resilience following Hurricane Maria in Puerto Rico. Methods: In April 2018, qualitative interviews (n = 22) were conducted with stakeholders in 7 Puerto Rican municipalities (9% of total). Transcripts were deductively and inductively coded and analyzed to identify salient topics and themes, then examined according to strategic themes from the Federal Emergency Management Association’s (FEMA) Whole Community Approach. Results: Municipal preparedness efforts were coordinated, community-based, leveraged community assets, and prioritized vulnerable populations. Strategies included (1) multi-sectoral coordination and strategic personnel allocation; (2) neighborhood leader designation as support contacts; (3) leveraging of community leader expertise and social networks to protect vulnerable residents; (4) Censuses of at-risk groups, health professionals, and first responders; and (5) outreach for risk communication and locally tailored protective measures. In the context of collapsed telecommunications, communities implemented post-disaster strategies to facilitate communication with the Puerto Rican Government, between local first responders, and to keep residents informed, including the use of: (1) police radios; (2) vehicles with loudspeakers; (3) direct interpersonal communication; and (4) solar-powered Internet radio stations. Conclusions: Adaptive capacities and actions of Puerto Rican communities exemplify the importance of local solutions in disasters. Expanded research is recommended to better understand contributors to disaster resilience.

Puerto Rico has long been understood by archaeologists as a key geographical location for understanding the succession of cultural occupations in the Caribbean (Alegría, 1965; Curet, 2006; Siegel, 2005.) Unfortunately, despite the importance of archaeology in this region, the island has been continuously effected by socio-economic instability, lack of archaeological funding opportunities, few specialized academic programs, and a heavy focus on cultural resource management (CRM) rather than academic research. Though more Puerto Rican-focused archaeologists have joined the academic discussion, publications in this area are still relatively low and heavily focused on CRM and salvage work. Poor funding and resources for non-consulting archaeological projects has relegated Puerto Rico to the “island with the lowest number of publications in the Spanish Caribbean.” (L.A. Current, 2006 pg. 656). This paper will highlight some of the limitations of working in Puerto Rican archaeology. We will use the experiences we gained from our research project at the La Mina archaeological site to shed light on some of the difficulties we encountered as well as (hopefully) encourage an increase in academic and financial support for this understudied region of the Caribbean.

Adaptation Practice

Farmers across the globe are experiencing compounding shocks that make evident the need to better understand potential drivers and barriers to strengthen adaptive capacity. This is especially true in the context of a disaster, where a disruption in the natural and built environment hinders livelihood strategies and exposes the underlying dynamics that perpetuate vulnerability to natural hazards. As such, the interconnections of structural and individual attributes must be considered when evaluating adaptive capacity. This paper uses a convergent mixed-methods approach to assess Puerto Rican farmers' actual and intended adoption of adaptation practices, in light of the obstacles they faced toward recovery after 2017's category four Hurricane Maria, to contribute to better understanding adaptive capacity. This study uses data from 405 farmers across Puerto Rico (87% response rate), surveyed 8 months after Maria by agricultural agents of the Extension Service of the University of Puerto Rico at Mayagüez. Quantitative data was assessed through negative binomial regressions (actual adoption) and generalized linear models (intended adoption), while qualitative data (reported obstacles) were analyzed through thematic analysis. This study found that almost half of farmers adopted an adaptation practice after Maria, and that in many cases, broader structures, such as systems of governance, farmers' social networks, and infrastructure, affect adaptive capacity more than individual perceptions of capacity. Future adaptation strategies and interventions, especially in the context of disaster, should consider the extent to which structural factors hinder individuals' ability to prepare for, respond, and recover from the impacts of these shocks. Our results show that there might be opportunity to enact new systems in light of catastrophic events, but this does not solely depend on individual actions. The mixed-methods approach used can inform future studies in better assessing adaptive capacity from a standpoint that incorporates individual and structural components.

The results obtained in two coffee fertilizer tests performed with the Puerto Rican variety of Coffea arabica on "Catalina Clay" are presented, statistically analyzed, and discussed. Nitrogen and phosphoric acid applications seem to be of greater importance as regards market-coffee production of the above variety in the soil type used, than are the applications of potash, which had no significant effects on the yields. These results are in sharp contrast with the results obtained by McClelland, who found potash applications to be essential and phosphoric acid applications to be not essential for maximum coffee production in Puerto Rico. It should be noted that McClelland's experiments were carried out on other soil types, which were probably not in condition to provide the coffee trees with their potash requirements.
