Although a number of investigations have concluded that lower latitudes are associated with increases in herbivore abundance and plant damage, the generality this pattern is still under debate. Multiple factors may explain lack consistency latitude–herbivory relationships. For instance, latitudinal variation pressure be shaped entirely or not by climatic variables, vary among guilds differing life‐history traits. Additionally, strength top–down effects from natural enemies on herbivores...
PREMISE OF THE STUDY: Coflowering plants are at risk for receiving pollen from heterospecifics as well conspecifics, yet evidence shows wide variation in the degree that heterospecific transfer occurs. Evaluation of patterns and correlates among‐ within‐species (HP) receipt is key to understanding its importance floral evolution species coexistence; however, rarity deeply sampled multispecies comparisons has precluded such an evaluation. METHODS: We evaluated HP load size diversity 19 across...
Although the effects of plant diversity on herbivores are contingent upon herbivore traits and source (e.g. intra‐ interspecific), most studies have analyzed these separately. We compared genotypic big‐leaf mahogany Swietenia macrophylla with that tree species two specialist caterpillars (Hypsipyla grandella stem borers Phyllocnistis meliacella leaf miners) three generalist leafhoppers (Cicadellidae) feeding in a large‐scale (7.2 ha) forest experiment southern Mexico. The consisted...
Although clinical applications represent the next challenge in single-cell genomics and digital pathology, we still lack computational methods to analyze or pathomics data find sample-level trajectories clusters associated with diseases. This remains challenging as single-cell/pathomics are multi-scale, i.e., a sample is represented by of cells/structures, samples cannot be easily compared each other. Here propose PatIent Level analysis Optimal Transport (PILOT). PILOT uses optimal transport...
ABSTRACT The richness and seasonal variation of ant‐plant interactions were compared in four habitats México: lowland tropical dry forest (La Mancha, Veracruz), coastal sand dune matorral (San Benito, Yucatán), semiarid highland vegetation (Zapotitlán, Puebla), lower montane humid (Xalapa, Veracruz). effects temperature precipitation on the distribution number differed among habitats. general linear models fitted to interaction curves explained 78.8 percent for La 80.1 Zapotitlán, 18 San...
Despite increasing evidence that plant intra- and inter-specific diversity increases primary productivity, such effect may in turn cascade up to influence herbivores, there is little information about effects on anti-herbivore defenses, the relative importance of different sources diversity, mechanisms for effects. For example, increased growth at high lead reduced investment defenses via growth-defense trade-offs. Alternatively, positive herbivore abundance which leads a greater defenses....
Summary Geographic variation in abiotic factors and species interactions is widespread hypothesized to generate concomitant patterns of trait variation. For example, higher rates herbivory at lower latitudes are thought select for increased plant defences, although latitudinal defences may also be influenced directly by indirectly predators parasitoids reducing herbivore pressure. We measured the herb R uellia nudiflora among 30 populations spanning a gradient from northern Yucatan southern...
ABSTRACT The contribution of dipterans to pollination in tropical communities has been scarcely studied. Although some studies have evaluated dipteran crops and wild species, limited attention paid their role networks. In particular, pollen transport neglected. Integrating as floral visitors importance through interaction networks may help reveal co‐flowering communities. We constructed visitation from the analysis carried on bodies two coastal test prediction that would fewer but more...
The acclimation, foraging behavior, and pollination efficiency of stingless bees the species Nannotrigona perilampoides Cresson were evaluated in tomato (Lycopersicon esculentum Mill.) plants cultivated two greenhouses. greenhouses divided into three areas 16 m2, one following treatments was used for pollination: (SB), mechanical vibration (MV), no (NP). Observations conducted once a week from 0800 to 1600 hours during 2 mo. acclimation estimated by number that did not return hive (lost...
Insufficient pollination is a function of quantity and quality pollen receipt, the relative contribution each to limitation may vary with intrinsic plant traits extrinsic ecological properties. Community-level studies are essential evaluate variation across species in under common conditions. This study examined whether endemic more limited by or than non-endemic co-flowering three endemic-rich communities located biodiversity hotspots different continents (Andalusia, California Yucatan)....
Abstract Species interactions are known to be key in driving patterns of biodiversity across the globe. Plant-plant through heterospecific pollen (HP) transfer by their shared pollinators is common and has consequences for plant reproductive success floral evolution, thus potential influence global community assembly. The literature on HP growing it therefore timely review causes among-species variation receipt at a scale, uncovering its contribution biodiversity. Here we analyzed published...
Abstract The number of co‐flowering species, floral density and trait diversity can be major determinants pollinator‐mediated plant–plant interactions in a community. However, evaluation how each one these components affects the pollination success single focal plant effects vary at different spatial scales, is lacking. Here, we evaluated functional (flower morphology colour), taxonomic (reflecting potential sampling effects) flower (conspecific heterospecific), on pollinator environment...
Abstract The ecological dynamics of co‐flowering communities are largely mediated by pollinators. However, current understanding pollinator‐mediated interactions primarily relies on how plants influence attraction shared pollinators, and much less is known about plant–plant that occur via heterospecific pollen (HP) transfer. Invaded in particular can be highly affected the transfer alien pollen, but strength, drivers fitness consequences these at a community scale not well understood. Here...
Abstract Despite the importance of native pollinators in agricultural systems, little is known about potential competitive interactions among them or way they exploit crops' floral resources. This study determines temporal use resources by, and interspecific between, bees Apis mellifera L. (Hymenoptera: Apidae) experimental plots squash, Cucurbita moschata (Duchesne ex Lam.) Duchesne Poir. (Cucurbitaceae), watermelon, Citrullus lanatus (Thunb.) (Cucurbitaceae). General specific niche overlap...
Although studies have shown that pollen addition and/or removal decreases floral longevity, less attention has been paid to the relationship between reproductive costs and longevity. In addition, influence of on longevity responses not yet evaluated. Here, orchid Cohniella ascendens is used answer following questions. (a) Does experimental flower buds in C. increase longevity? (b) decrease does this response depend plant resource status?To study effect 21 plants were selected from which we...
Background: Coastal ecosystems in Mexico remain understudied spite of their ecological, economic and conservation value are being impacted by human activities along the coast. Knowledge on spatial patterns plant species distribution that helps preserve these fragile is crucial.Aims: We evaluated differences richness, diversity dominance 16 communities as well degree to which were driven climatic conditions sandy dunes Yucatán. importance invasive mediating patterns.Results: found wide...
The interactions between pairs of native and alien plants via shared use pollinators have been widely studied. Community level studies however, are necessary in order to fully understand the factors mechanisms that facilitate successful plant invasion, but these still scarce. Specifically, few community considered how differences invasion (alien flower abundance), degree floral trait similarity invasive species, mediate effects on plant-pollinator communities. Here, we evaluated role species...
