Abstract Southern calamary (Sepioteuthis australis) in Tasmania form spawning aggregations in Great Oyster Bay on the central east coast of Tasmania during spring/summer; these are targeted by commercial fishers. However, it is not known if there are similar aggregations farther south in Tasmania or at other times of the year, mainly because the species lives for less than a year. Therefore, this study describes and identifies differences in reproductive ecology of southern calamary on the east and southeast coasts of Tasmania, by sampling adults and surveying egg masses at inshore sites in both regions. Inshore populations on both coasts showed a similar seasonal trend of large gonosomatic index, reproductive output, and body size, and of greatest abundance during spring, and lowest in autumn. The number of egg masses was higher on the east coast, where mature calamary formed large spawning aggregations during spring and summer. However, there were no such aggregations during winter or autumn. Along the southeast coast, spawning activity was sporadic, resulting in isolated, low density, egg patches deposited over broader areas during spring, summer, and winter. There was no evidence of areas of seagrass or macroalgae associated with large depositions of egg masses at any time on the southeast coast. It appears that, by adopting different spawning behaviour in different locations and seasons, southern calamary may spread the risk of mortality in both space and time. The biological significance of this is unclear, particularly with respect to understanding the mechanisms that drive the development of spawning aggregations. Both spatial and seasonal spawning patterns appear to result from specific use of inshore sites at certain times of the year.

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD—with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.

Hill Country

Large areas of North Island hill country are producing below potential as a result of low fertility and poor pasture composition. Removal of undesirable species and replacement with a higher producing pasture is essential for increased productivity but is difficult to achieve. A development programme is described where the use of glyphosate in close association with oversowing and stock management has allowed rapid pasture establishment, marked increase in carrying capacity and a quick return on investment. Keywords: Pasture establishment, glyphosate, oversowing, white clover, subdivision, productivity.

Lincoln Park

In late September 2018, multiple generations of Chicago’s storied social movements marched through Chicago’s Lincoln Park neighborhood as part of the sold-out, three-day Young Lords Fiftieth Anniversary Symposium hosted by DePaul University—an institution that, alongside Mayor Richard J. Daley’s administration, had played a sizeable role in transforming Lincoln Park into a neighborhood “primed for development.” Students, activists, and community members—from throughout Chicago, the Midwest, the East Coast, and even as far as Texas—converged to celebrate the history of Puerto Ricans in Chicago, the legacies of the Young Lords, and the promises and possibilities of resistance. As Elaine Brown, former chairwoman and minister of information for the Black Panther Party, told participants in the second day’s opening plenary, the struggle against racism, poverty, and gentrification and for self-determination and the general empowerment of marginalized people is a protracted one. “You have living legends among you,” Brown insisted, inviting us to associate as equals with the Young Lords members in our midst. Her plea encapsulated the ethos of that weekend’s celebrations: “If we want to be free, let us live the light of the Lords.”
