Larvae of the bruchid beetle Caryedes brasiliensis (Bruchidae) develop entirely within the seed of the neotropical legume DiocIea megacarpa. The seed contains an appreciable concentration of L-canavanine, a potent ...

In the premontane rain forests of northwest Costa Rica, patches of secondary forest can contain high densities of large Vriesea spp. bromeliads. Such patches contain an average of 6,470 ± 1,080 (s.e.) larvae ha-1 of the ...

The processes of arc initiation at the margin of an oceanic plateau are remarkably well preserved along the southern coastline of eastern Costa Rica and western Panama. We present new results of a combined tectonostratigraphic ...

Insect parasitoids may be an exception to the typical biogeographic pattern of increasing species richness at lower latitudes exhibited by most taxa. Evidence for this ‘anomalous’ latitudinal gradient has been derived from ...

A new genus of Xanthopygina rove beetles is described here as Lendatus gen. nov. The new genus includes three new species: L. bolivianus sp. nov., described from Bolivia, L. philothalpiformis sp. nov. described from Costa ...

Understanding the relationship between multi-level institutional linkages and conditions influencing the likelihood of successful collective action has practical and theoretical relevance to sustainable local resource ...

During the ir spring night ~a.'W n. free-ranging male cecropia moths lived a maximum of 12 days (one of 124 recaptu red moths of 387 relea~d moths). The number of survivors declined precipitiously after day fi ve: five ...

Countless seamounts occur on Earth that can provide important constraints on intraplate volcanism and plate tectonics in the oceans, yet their nature and origin remain poorly known due to difficulties in investigating the ...

Tropical conservation biology is inescapably the biology of habitat fragments and has been focused on habitat decay. Habitat restoration is primarily the initiation. growth. and coalescence of habitat fragments. Management of ...
