Abstract

In highly transformed regions, such as the tropical Andes, identifying the influence of forest succession and soil fauna on non-additive effects of litter decomposition is crucial for gaining a more realistic understanding of carbon dynamics and nutrient cycles. The objective of this paper was to analyze the changes of litter mixture effects on decomposition between different soil fauna treatments (macrofauna inclusion vs macrofauna exclusion) and successional stages (mature forests vs secondary forests) in upper Andean tropical forests along time by using a reciprocal translocation experiment of 1,344 litterbags that ran for 18 months with six common native Andean species. Thought t-tests, linear regressions, and linear mixed models, I found that litter mixture effects vary among sites and increase with time in secondary forests until the year of decomposition in litterbags with macrofauna exclusion. Mature forests exhibited strong antagonistic effects, while pronounced synergistic effects were observed in secondary forests. Although soil macrofauna did not increase significantly litter decomposition and synergistic effects in the mixtures at any of the stages of decay, it is likely that soil macrofauna may impact litter mixtures through top-down effects within soil food webs, rather than exerting a direct effect in the litter consumption as has been reported in tropical lowland ecosystems. Overall, this study supports the idea that litter mixtures exhibit significant variability across sites, can change with successional stage, and are influenced by soil fauna depending on the stage of decay in tropical Andean montane forests.

5. Sexual Size Dimorphism in 28 Neotropical Bat Species Fails to Obey Rensch's Rule.

Author

Castillo-Figueroa, Dennis

Abstract

Sexual size dimorphism (SSD) is the difference in body size between males and females. One of the most studied patterns in allometric size difference between sexes is Rensch's rule, which describes an increase of SSD with increasing species size when males are the larger sex. However, few studies have tested this rule in bats, and morphological structures other than body size have rarely been included. The objective of this paper was to analyze the patterns of SSD across 28 New World bat species and assess their conformity to Rensch's rule. To do this, I obtained measurements of forearm length, length of the third digit, and length of the fifth digit from 1,151 bat specimens, and through t-tests and reduced major axis regressions, I analyzed patterns of SSD and Rensch's rule. I found high variation in size and wing morphology, with a modest female-biased size in more than half the species, which fails to support Rensch's rule. Larger wing structures in females can improve flight performance to overcome aerodynamic challenges during reproduction when carrying pups and foraging for food. Mechanisms other than body size in females, geographic variation, and the set of species selected may explain the isometric pattern between sexes, which invalidates Rensch's rule for Neotropical bats. Further studies should encompass a broader range of bat species from different lineages, but it is also necessary to analyze SSD based on various traits related to resource use, such as wing and nasal morphology, as well as include the influence of geographic variation and environmental factors. El dimorfismo sexual del tamaño (DST) es la diferencia en el tamaño corporal entre machos y hembras. Uno de los patrones mas estudiados en la diferencia de tamaño alométrico entre sexos es la regla de Rensch que describe un aumento del DST con el aumento del tamaño de la especie cuando los machos son el sexo más grande. Sin embargo, existen pocos estudios realizados en murciélagos y en contadas ocasiones se han incluido estructuras morfológicas distintas del tamaño corporal para probar esta regla. El objetivo de este artículo fue analizar los patrones de DST en 28 especies de murciélagos neotropicales y evaluar la validez de la regla de Rensch. Para ello, obtuve medidas de la longitud del antebrazo, longitud del tercer y quinto dígito de 1,151 especímenes de murciélagos, y a través de pruebas t y de regresiones de eje mayor reducido, analicé patrones de DST y la regla de Rensch. Encontré una gran variación en el tamaño y la morfología alar con un ligero aumento de las hembras en más de la mitad de las especies, lo cual no respalda la regla de Rensch. Estructuras alares más grandes en las hembras pueden mejorar el rendimiento de vuelo para superar los desafíos aerodinámicos durante la reproducción cuando cargan a las crías y buscan alimento. Mecanismos distintos del tamaño corporal en las hembras, así como la variación geográfica, y el conjunto de especies seleccionadas pueden explicar el patrón de isometría entre sexos que invalida la regla de Rensch para murciélagos neotropicales. Futuros estudios deberían abarcar una mayor variedad de especies de murciélagos de diferentes linajes, pero también es necesario analizar el DST en función en diversos rasgos relacionados con el uso de recursos, como la morfología alar y nasal, además de incluir la influencia de la variación geográfica y los factores ambientales.

Abstract

Deadwood is a large global carbon store with its store size partially determined by biotic decay. Microbial wood decay rates are known to respond to changing temperature and precipitation. Termites are also important decomposers in the tropics but are less well studied. An understanding of their climate sensitivities is needed to estimate climate change effects on wood carbon pools. Using data from 133 sites spanning six continents, we found that termite wood discovery and consumption were highly sensitive to temperature (with decay increasing >6.8 times per 10°C increase in temperature)—even more so than microbes. Termite decay effects were greatest in tropical seasonal forests, tropical savannas, and subtropical deserts. With tropicalization (i.e., warming shifts to tropical climates), termite wood decay will likely increase as termites access more of Earth’s surface.

Abstract

A pesar de que las sabanas neotropicales han sido sometidas a procesos continuos de transformación del paisaje (por ejemplo, la agricultura, la industria de petróleo, gas e hidrocarburos), muy poco se sabe sobre la ecología e historia natural de grupos biológicos importantes como los mamíferos terrestres, y la información asociada con los aspectos comportamentales de las especies de mamíferos que habitan estos ecosistemas es especialmente escasa. El objetivo del estudio fue describir los patrones de actividad de mamíferos medianos y grandes en dos ecosistemas de sabana de los Llanos colombianos. Se instalaron 60 cámaras trampa en los dos ecosistemas durante 35 días (2100 días-cámara). Se describieron los patrones de actividad de nueve especies predominantemente nocturnas. No se encontraron diferencias en las distribuciones circadianas de mamíferos entre ecosistemas. Cuniculus paca Linnaeus 1758 y Dasyprocta fuliginosa Wagler 1832 mostraron patrones de exclusión explicados probablemente por la competencia, en tanto que otras especies como Tamandua tetradactyla Linnaeus 1758 y Myrmecophaga tridactyla Linnaeus 1758 mostraron patrones de actividad similares. Se destaca la importancia de las sabanas para la conservación de estas especies y se discute la relevancia de los estudios sobre patrones de actividad para la ecología y conservación de mamíferos en las sabanas neotropicales. Neotropical savannas have undergone continuous processes of landscape transformation (e.g., agriculture, oil, gas, and hydrocarbon industry) and very little is known about the ecology and natural history of key biological groups such as terrestrial mammals while the information on behavioral aspects of mammalian species in these ecosystems is very scarce. Here, we aimed to describe the activity patterns of medium and large mammals in two savanna ecosystems in the Colombian Llanos. A set of 60 camera traps was installed in the two ecosystems for 35 days (2100 camera days). We described the activity patterns of nine predominantly nocturnal species. We found no difference in circadian distributions of mammals between ecosystems. Cuniculus paca Linnaeus 1758 and Dasyprocta fuliginosa Wagler 1832 showed patterns of exclusion probably due to competition whereas other species like Tamandua tetradactyla Linnaeus1758 and Myrmecophaga tridactyla Linnaeus 1758 displayed similar activity patterns. We highlight the importance of savannas for the conservation of these species and discuss the relevance of studies on activity patterns for mammal ecology and conservation in Neotropical savannas.

Abstract

Deadwood is a large global carbon store with its store size partially determined by biotic decay. Microbial wood decay rates are known to respond to changing temperature and precipitation. Termites are also important decomposers in the tropics but are less well studied. An understanding of their climate sensitivities is needed to estimate climate change effects on wood carbon pools. Using data from 133 sites spanning six continents, we found that termite wood discovery and consumption were highly sensitive to temperature (with decay increasing >6.8 times per 10°C increase in temperature)-even more so than microbes. Termite decay effects were greatest in tropical seasonal forests, tropical savannas, and subtropical deserts. With tropicalization (i.e., warming shifts to tropical climates), termite wood decay will likely increase as termites access more of Earth's surface.
