RESUMO Este trabalho fez uma análise bibliométrica da repercussão internacional do livro "Studies on termites from the Mato Grosso State, Brazil", de AGA Mathews (1977). O número de citações aumentou ao longo dos anos após a primeira citação. O livro de Mathews foi citado em artigos e revisões, teses e dissertações, livros e capítulos, resumos em anais de eventos e notas científicas. A maioria destes trabalhos é empírico e descritivo. Os estudos foram realizados em 35 países das regiões Neotropical, Paleártica, Afrotropical, Neártica, Australásia e Indomalaia. Entretanto, 55% dos trabalhos foram realizados no Brasil. As revistas Sociobiology e Insectes Sociaux, cujo escopo é publicar pesquisas sobre insetos sociais, apresentam o maior número de artigos que citaram Mathews. A maioria dos 71 autores que citaram Mathews mais de duas vezes é brasileiro. Constrictotermes cyphergaster (Silvestri) foi a espécie mais estudada em 80% dos trabalhos que abordaram Isoptera. As palavras-chave mais frequentes (termite, Isoptera, taxonomy), são termos generalistas que foram associadas à maioria dos países. A maioria das pesquisas foi executada em laboratórios e em áreas de vegetação nativa. Estudos em agroecossistemas foram realizados predominantemente no Brasil. Este estudo mostra a diversidade de aplicações (citações) do livro Mathews, e que o número de citações tende a aumentar devido à grande quantidade de informações apresentadas pelo autor.

ABSTRACT This paper consists on a bibliometric analysis of the international influences of the book "Studies on termites from the Mato Grosso State, Brazil", by AGA Mathews (1977). The number of citations has increased over the years after the first citation. Mathews book was cited in articles, reviews, theses, dissertations, books, book chapters, abstracts in conference proceedings, comments and scientific notes. Most these studies are empirical and descriptive. The studies were conducted in 35 countries of the Neotropical, Palearctic, Afrotropical, Nearctic, Australasia and Indomalaya regions. 55% of the studies were carried out in Brazil. The journals Sociobiology and Insectes Sociaux, have social insect studies within its scope, and the highest number of articles citing Mathews. Most of the 71 authors that cited Mathews more than twice are Brazilian. Constrictotermes cyphergaster was the most studied in over 80% of the studies addressing Isoptera. The most frequent keywords were termite, Isoptera and taxonomy, generalist terms indexed in most publications carried out in different countries. Most of the research studies were carried out in laboratories and native vegetation areas. Studies in agroecosystems were implemented predominantly in Brazil. This study shows the diversity of application (citations) of Mathews' book, and that the number of citations will continue to increase due to the large amount of information presented by the author.

Habitat fragmentation is one of the main threats to the biodiversity of the planet. This study was conducted in nine fragments of the Brazilian cerrado (savanna) sensu stricto. We assessed the effects that fragment size and distance between fragments has on the density and fertility of populations of Byrsonima pachyphylla A. Juss. (Malpighiaceae), known in Brazil as "murici". In each of the nine fragments, we evaluated seven individuals. We quantified the B. pachyphylla density within a 20-m radius around each individual. Fertility in each fragment was estimated by determining the ratio between the number of flowers and the number of fruits produced. We carried out linear regression analyses between mean B. pachyphylla density and fragment size, as well as between mean B. pachyphylla fertility and fragment size. The influence of spatial autocorrelation on the fertility of each studied plant was estimated by Moran's I to evaluate the effect of fragment distance on B. pachyphylla fertility. Population densities and the proportions of fertile plants were greater in the larger fragments, which were also more preserved. There was spatial autocorrelation only between plants in the same fragment. Neighboring fragments differed significantly in terms of fertility, which is probably related to the degree of preservation of each fragment. Habitat fragmentation has a marked effect on the fertility of plant species in the cerrado, and larger fragments are needed in order to maintain their populations and those of associated species.
