ABSTRACT
The number of citations that papers receive has become significant in measuring researchers' scientific productivity, and such measurements are important when one seeks career opportunities and research funding. Skewed citation practices can thus have profound effects on academic careers. We investigated (i) how frequently authors misinterpret original information and (ii) how frequently authors inappropriately cite reviews instead of the articles upon which the reviews are based. To reach this aim, we carried a survey of ecology journals indexed in the Web of Science and assessed the appropriateness of citations of review papers. Reviews were significantly more often cited than regular articles. In addition, 22% of citations were inaccurate, and another 15% unfairly gave credit to the review authors for other scientists' ideas. These practices should be stopped, mainly through more open discussion among mentors, researchers and students.

Chinchilla lanígera é um roedor proveniente do Chile e sua criação é com fins comerciais. As doencas parasitarias, principalmente giardíase podem causar problemas clínicos e sanitarios, causando perdas produtivas e económicas. Foram colhidas amostras de fezes de 220 chinchilas de urna criação comercial no sul do Brasil e 35 amostras de chinchilas da Reserva Nacional las Chinchillas no Chile, e submetidas ão método de Faust e colaboradores. O total de amostras positivas para cistos de Giardia sp. foi de 31,37 por cento (80/255); da criação comercial foi de 36,36 por cento(80/220). O número de amostras que apresentaram mais de 5 cistos/campo foi 4,55 por cento(10/220). Todas as amostras dos animáis da Reserva foram negativas. Não houve associação entre a positividade e a faixa etária dos animais analisados.
Chinchilla lanígera is a rodent native to Chile which is bred for commercial purposes. Parasitic diseases, mainly giardiasis, may cause clinical and sanitary problems and lead to production and economic losses. Fecal samples were collected from 220 chinchillas pertaining to a commercial breeding facility in southern Brazil and from 35 chinchillas from Las Chinchillas National Reserve in Chile. All samples were analyzed using the method proposed by Faust et al. Positive samples for Giardia cysts amounted to 31.37 percent (80/255); 36.36 percent (80/220) was recovered from the commercial breeding facility. The rate of samples with over 5 cysts/field was equivalent to 4.55 percent (10/220). All of the samples collected from the National Reserve were negative for Giardia sp. No association was found between positive rates for Giardia sp. and the age of chinchillas.

A female of Amblyomma aureolatum was found on the howler monkey Alouatta guariba, in Cachoeira do Sul, Rio Grande do Sul, Southern Brazil. This is the first record of this tick species parasitizing this primate species in Brazil.
