“…In an Appalachian hardwood forest, the herbaceous component of the herb layer was significantly greater in young clear-cut stands than in mature stands, whereas the woody component of the herb layer was significantly greater in mature stands [9]. Pinard et al [39] also suggested that forest management decisions should consider the type of plant-animal interaction in relation to seed dispersal. Since such traits are probably good indicators of the effects of the forest management systems used, we focused not only on diversity indices but also on the ecological characteristics of the species found in each type of forest.…”

-We compared the plant species diversity of forest-floor vegetation in long-rotation Larix kaempferi plantations with standardrotation plantations and abandoned coppice forest in central Japan. Species diversity and richness did not differ between the standard-and longrotation plantations. However, the composition of tall-tree species, of different seed-dispersal types, in long-rotation plantations differed from that in standard-rotation plantations, but was similar to that in abandoned coppice forest. These results indicate that, in particular, long-rotation plantations contained more tall-tree species with animal-dispersed seeds, which in turn suggests that long-rotation plantations may be better for colonization of tall-tree species with this type of seed dispersal. The relatively long period since management in long-rotation plantations may play a significant role in the growth, reproduction, and seedfall of naturally regenerated tall-tree species with animal-dispersed seeds. Therefore, long-rotation plantations may maintain and restore species composition via recovering ecological function.forest ecosystem management / seed dispersal / species classification / life form Résumé -Effets de l'allongement de la période de rotation des plantations de Larix kaempferi au centre du Japon sur la diversité en espèces végétales. Nous avons comparé la diversité en espèces végétales du sous bois entre des plantations de Larix kaempferi menées en rotations longues par rapport à des rotations classiques courtes ou des taillis abandonnés. La diversité et la richesse en espèces végétales ne diffèrent pas entre les plantations classiques et les plantations à longue rotation. Cependant, la diversité de la strate arborée, avec des stratégies de dispersion des graines différentes, diffère entre les plantations à longue durée par rapport aux plantations classiques mais est semblable aux taillis abandonnés. Les résultats indiquent en particulier que les plantations avec de longues rotations contiennent plus d'espèces arborées avec une stratégie de dissémination des graines par zoochorie ce qui suggère également que ce type de plantation longue soit favorable aux arbres avec ce type de dissémination. La longue période après la dernière intervention en forêt dans les plantations à longue rotation semble donc jouer un rôle important dans la croissance, la reproduction et la dispersion des graines par zoochorie pour les arbres se régénérant naturellement. Par conséquent, les plantations à longue rotation pourraient maintenir et restaurer la composition en espèces végétales par rétablissement de la fonction écologique. gestion des écosystèmes forestiers / stratégie de dispersion des graines / classification des espèces / type biologique

“…Assim como o corte de cipós e a anelagem de árvores competidoras, a exploração florestal também contribui com o aumento da capacidade produtiva da floresta remanescente (PINARD et al, 1999). As técnicas de EIR constituem-se do planejamento da exploração florestal, desenvolvimento de infraestrutura e técnicas operacionais, as quais objetivam reduzir os danos ambientais da extração da madeira, enquanto aumentam a eficiência das operações (BOLTZ et al, 2003).…”

Efeito da silvicultura pós-colheita na população de Chrysophyllum lucentifolium Cronquist (Goiabão) em uma floresta de terra firme na amazônia brasileira

RESUMO -Avaliou-se o crescimento de uma população de Chrysophyllum lucentifolium Cronquist (goiabão), considerando árvores com diâmetro igual ou superior a 35 cm, em 700 ha de floresta natural de terra firme explorada com técnicas de impacto reduzido, seguidas de tratamentos silviculturais, no Município de Paragominas, PA, Amazônia brasileira. Foram estabelecidos sete tratamentos, com quatro repetições de 25 ha em cada um, em que foram aplicados os tratos silviculturais, que constaram de corte de cipós e anelagem de árvores competidoras. O crescimento da espécie foi determinado por meio do incremento periódico anual em diâmetro, no período de 2005 a 2009. Além das medidas de diâmetro, foram observadas as formas das copas das árvores e a intensidade de luz recebida pelas copas. Chrysophyllum lucentifolium não respondeu significativamente aos tratamentos silviculturais, ou seja, a anelagem e o corte de cipós parecem não ter influenciado o crescimento da espécie no período de cinco anos. No entanto, as árvores com diâmetro de 40 a 49 cm, com copas de forma regular e recebendo alta intensidade de luz, cresceram mais, na maioria dos tratamentos. Portanto, é provável que o incremento ainda vá aumentar nos anos seguintes, embora em outras áreas da Amazônia o efeito da abertura do dossel tenha estimulado o crescimento das árvores apenas até o final do terceiro ano após a exploração. Outras avaliações silviculturais da espécie devem ser realizadas para constatar se houve aceleração no crescimento nos últimos anos ou se há a necessidade de aplicar novamente os tratos silviculturais.Palavras-chave: Crescimento de espécies arbóreas; Tratamentos silviculturais; Corte de cipós.

“…Forest management for economic purposes can affect the availability of plant species and of natural cavities and hollows. Consequently, population densities of animals utilizing them can be affected (Pinard et al 1999, Eltz et al 2003 in two ways: by the mortality caused by the fall of trees during timber exploration (selective or not), and indirectly, by the lower availability of cavities.…”

“…In mature forests, the abundance and diversity of birds that nest in cavities tend to increase as the forest ages (Newton 1994). Selective timber explorations decrease the density of larger trees in tropical forests, which are more prone to have trunk and twig cavities and hollows (Kerr et al 1999, Pinard et al 1999). …”

Neotropical Entomology 35(3): 285-298 (2006) Revisão sobre a Influência de Fatores Proximais na Nidificação de Vespas e Abelhas Solitárias (Hymenoptera: Aculeata) em Cavidades Pré-Existentes no Lenho PALAVRAS-CHAVE: Vespa solitária, abelha solitária, guilda, cavidade em árvores, ninho-armadilha ABSTRACT -Guilds of Aculeate solitary wasps and bees that nest in preexisting cavities in wood are important components of terrestrial ecosystems because they engage in several ecological interactions (e.g. predation and pollination) with other species of plants and animals. Spatial and temporal variations in richness and abundance of solitary wasps and bees can be related to changes in environmental structure and in the diversity of other groups of organisms. The nesting period of these Aculeata is their most critical life cycle stage. Females of solitary wasp and bee species invest relatively more time constructing and provisioning their nests than do females of social species. Differently from species that nest in the soil or construct exposed nests, the main factors affecting the reproductive success of solitary species nesting in preexisting wood holes are still unknown. Our objective is to provide an overview of the role of proximate causes of nesting failure or success among solitary wasps and bees (Aculeata), for designing effective conservation and management strategies for these Hymenoptera.
