AbstractNest predation can threaten marine turtle nesting success, and having to address dissimilar predator species complicates nest protection efforts. On Florida's Keewaydin Island predation by raccoons Procyon lotor and invasive feral swine Sus scrofa are disparate, significant threats to marine turtle nests. Using 6 years of nesting data (mostly for loggerhead marine turtles Caretta caretta) we examined the impacts of swine predation on nests and the benefits of swine eradication, caging nests to protect them from raccoon predation, and the effects of nest caging on swine predation. Nest predation by swine began in mid nesting season 2007, after which swine quickly annihilated all remaining marine turtle nests. During 2005–2010 raccoon predation rates for caged nests (0.7–20.4%) were significantly lower than for uncaged nests (5.6–68.8%) in every year except 2009, when little raccoon predation occurred. The proportions of eggs lost from raccoon-predated nests did not differ between caged and uncaged nests. Caging did not prevent destruction by swine but median survival time for caged nests was 11.5 days longer than for uncaged nests, indicating that caged eggs in nests have a greater chance of hatching before being predated by swine. The financial cost of the eradication of swine greatly outweighed the value of hatchlings lost to swine predation in 2007.

Data from a focus group of nine Latina parents, specifically mothers from a South Texas border region known as the Rio Grande Valley, were analyzed using a qualitative methodology. Grounded in the theory of social capital, the purpose of the study was to understand the perceptions and experiences of Latina parents related to accessing information and resources to aid their students in enrolling in postsecondary institutions. The study was an exploratory, descriptive, and qualitative one that used a naturalistic paradigm. Findings showed that Latina parents perceived gaining information and resources related to increasing their understanding of college readiness, college knowledge, and college access as challenging. In addition, findings indicate that despite challenges, the mothers did receive support along the way. As parents, they want to get their students not only to the college door but through the college door, declaring that their children will go to college. They recognize there are keys to helping guarantee access to college, and it is these keys that these mothers seek. Such findings are important because the national portrait of college enrollment and attainment of college degrees shows continuing inequalities based on class, race/ethnicity, and income, especially for Latina/o first-generation students. Yet, few studies have considered the perceptions and experiences of Latina/o parents related to accessing information and resources to support their students when preparing for, applying to, and enrolling in postsecondary institutions.

Elk (Cervus canadensis), a native species on the Canadian Prairies, makes extensive use of agro-ecosystems. Feral Swine (Sus scrofa) is a highly invasive species introduced to western Canada in the late 1980s; it is now endemic and rapidly expanding its range across the Canadian Prairies. Here we consider a series of 14 trail camera photos obtained near St. Breiux, Saskatchewan on 18 November 2018. Taken at night over 67 minutes, they document close, non-aggressive encounters between Elk and Feral Swine. We believe that these are the first documented observations of close (<5 m) interactions between free-ranging Elk and Feral Swine in North America that include no indications of fear response or displacement of one species by the other. These types of indirect interactions among species have important implications in terms of potential risk of disease transmission and interpreting potential ecological impacts of invasive Feral Swine on native large mammals.

Foi investigado o valor diagnóstico da resposta alérgica cutânea em leitões experimentalmente sensibilizados, pela via intramuscular, com suspensões oleosas de Mycobacterium bovis ou M. avium inativados pelo calor.Foram utilizados 91 animais, divididos em quatro grupos: grupos A e B, cada um com 25 indivíduos, grupos C e D com 21 e 20 indivíduos respectivamente, balanceando-se as características de raça, linhagem, faixa etária e sexo. Aos 30 dias de idade, todos os animais foram submetidos a uma triagem com a aplicação de tuberculina PPD bovina, pela via intradérmica na base da orelha e não houve qualquer tipo de reação. Decorridos 60 dias do teste tuberculínico de triagem, o grupo A recebeu injeção intramuscular de 0,5 mL de uma suspensão oleosa de M. avium estirpe D4; o grupo B recebeu 0,5 mL de uma suspensão oleosa de M. bovis estirpe AN5; o grupo C (controle I), recebeu 0,5 mL do adjuvante oleoso; e o grupo D (controle II), recebeu 0,5 mL de solução fisiológica. Após 30 dias da sensibilização foi realizada a prova de tuberculinização comparativa com reação medida pela variação da espessura da pele com cutímetro de mola às 0h, 24h, 48h e 72h, após a aplicação das tuberculinas. No teste comparativo, lido às 48 ou 72 horas, a reação foi considerada negativa quando a diferença das reações entre o PPD bovino e o PPD aviário foi menor que 6,7 mm; suspeito ou inconclusivo quando a diferença se situou na faixa de 6,7 a 7,5 mm; e positiva de acordo com o tipo de PPD, considerando-se tuberculose para PPD M. bovis e micobacteriose para PPD M. avium, quando a diferença da reação foi superior a 7,5 mm.
