Os insetos como agentes polinizadores da mangueira [PDF]

Anais da Escola Superior de Agricultura Luiz de Queiroz, 1959
The authors study the insect population that visit the mango trees and search for their pollinizing activity. Prior operations showed that very few bees (Apis mellifera) visited the flowers of mango trees. It was known that the percentage of fecundation is low (Simao 1955), Popenoe (1929), Spencer and Kennard (1955), Lynch and Mustard (1955), Ruehle ...

Misión Polinizadores: ciencia ciudadana para conectar a Bogotá con sus abejas y polinizadores

Este cuadernillo presenta un protocolo de ciencia ciudadana diseñado para talleres públicos en Bogotá, con el fin de introducir a familias y jóvenes a la diversidad de polinizadores urbanos y a técnicas básicas de observación de interacciones planta–polinizador.

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes. [PDF]

Conserv Biol
Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

Exploring the importance of aromatic plants' extrafloral volatiles for pollinator attraction. [PDF]

New Phytol
Summary Aromatic plants occur in many plant lineages and have widespread ethnobiological significance. Yet, the ecological significance and evolutionary origins of aromatic volatile emissions remain uncertain. Aromatic emissions have been implicated in defensive interactions but may also have other important functions.

Setting goals for pollinator gardens. [PDF]

Conserv Biol
Abstract In recent years, declines in animal pollinators have stimulated tremendous interest in pollinator‐friendly gardening. There is a widespread notion that pollinator gardens are beneficial, but the specific capacity of pollinator gardens to improve biodiversity conservation and societal well‐being remains unclear.

Gene Flow and Vertical Stratification of Pollination in the Bat-Pollinated Liana <i>Marcgravia longifolia</i>. [PDF]

Ecol Evol
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

Integrating data to assess occupancy patterns of an endangered bumble bee. [PDF]

Conserv Biol
Abstract There is growing interest in integrating community science data with structured monitoring data to estimate changes in distribution patterns of imperiled species, including pollinators. However, significant challenges remain in determining how unstructured community science data should be incorporated into formal analyses of species ...

Variación interespecífica de ensambles de polinizadores en Nierembergia (Solanaceae) en relación con la localización geográfica y la variación fenotípica de las flores

Ecología Austral, 2022
Comprender cómo varían las interacciones de especies emparentadas de plantas con polinizadores a escala espacial permite establecer vínculos entre patrones macroevolutivos y procesos microevolutivos, y aproximarse a los mecanismos que subyacen a la ...

Effects of land cover and protected areas on flying insect diversity. [PDF]

Conserv Biol
Abstract Widespread insect losses are a critical global problem. Mitigating this problem requires identifying the principal drivers across different taxa and determining which insects are covered by protected areas. However, doing so is hindered by missing information on most species owing to extremely high insect diversity and difficulties in ...
