En Guatemala, el venado Cola Blanca es de los animales cinegéticos más importantes y sin duda de los más perseguidos a pesar de eso, se han realizado pocos estudios sobre él. En la actualidad, con la formación de la colección de la Fábrica de Municiones del ejército-FME-localizada en el municipio de Cobán, en el departamento de Alta Verapaz, se busca asegurar la conservación de esta especie. El estudio consistió en observaciones diarias para determinar el comportamiento general: social, productivo, reproductivo del venado y colectas de campo realizadas en las épocas de menor y mayor precipitación, con el objeto de obtener información acerca de la calidad de las principales plantas forrajeras, mediante análisis por el método de Weende. Se cuantificó la disponibilidad del forraje, utilizando porcentajes estimados de cubierta, para las plantas herbáceas y para arbustos y árboles se usó el muestreo sistemático por medio de parcelas de 10 x 10 m. Las plantas forrajeras principales fueron hierbas graminoides por existir en mayor disponibilidad (75%), luego los arbustos (22%), y por último las especies arbóreas (3%). Los forrajes consumidos fueron generalmente de calidad inferior que los forrajes de otras latitudes. Dentro de las especies arbustivas cabe mencionar como las más importantes para el venado del área, el clavel de Panamá (Hibiscus rosasimensis),pera (Pyrus communis) y Costa Rica (Bahuinia sp.). Estas especies junto con gramíneas como Andropogon bicornis, Panicum sellowii y Paspalum conjugatum, constituyen la base alimenticia del venado Cola Blanca en la FME. Los datos presentados sobre comportamiento social, sugieren diferencias en algunas estrategias sociales y de comportamiento a una edad temprana entre la población estudiada en semicautiverio y los reportes para poblaciones que habitan áreas silvestres o en completo cautiverio. Las hembras generalmente tienen sus crías en marzo, con un pico de nacimientos al final de dicho mes, aunque este es un período que puede prolongarse hasta mediados de abril. Lo que se observa en Cobán es una estacionalidad en la época de partos, lo cual concuerda con los factores climáticos que están relacionados con la sobrevivencia de los cervatos. Se infiere que los cervatos nacidos durante los meses de marzo y abril tendrán una mayor probabilidad de sobrevivencia que aquellos nacidos después o antes de la estación.Cuando las lluvias fuertes se presentan los cervatos son capaces fisiológicamente de utilizar los recursos vegetativos disponibles para su crecimiento y desarrollo. Por otra parte, las madres se recuperan de la tensión fisiológica como consecuencia de la lactancia.

Ungulate herbivory occurring within a forest plant community’s natural range of variation may help maintain species diversity. However, acute or chronically elevated levels of herbivory can produce dramatic changes in forest communities. For example, chronically high levels of herbivory by white-tailed deer (Odocoileus virginianus Zimmerman) in regions of historically low abundance at northern latitudes have dramatically altered forest community composition. In eastern hemlock (Tsuga canadensis L. Carrière) stands where deer aggregate during winter, high deer use has been associated with a shift towards deciduous species (i.e., maples [Acer spp.]) dominating the regeneration layer. Especially harsh winters can lead to deer population declines, which could facilitate regeneration of species that have been suppressed by browsing, such as hemlock. To enhance our understanding of how fluctuations in herbivory influence regeneration dynamics, we surveyed regeneration and deer use in 15 relict hemlock stands in the western Upper Peninsula of Michigan in 2007 and again in 2015. With the exception of small seedlings (0.04–0.24 m height), primarily maples whose abundance increased significantly (p < 0.05), we observed widespread significant declines (p < 0.05) in the abundance of medium (0.25 ≤ 1.4 m height) and large regeneration (>1.4 m tall ≤ 4 cm diameter at breast height) over the study period. Midway through our study period, the region experienced a high severity winter (i.e., “polar vortex”) which resulted in a substantial decline in the white-tailed deer population. Given the dominance of maples and dearth of hemlock in the seedling layer, the decline in the deer population may fail to forestall or possibly hasten the trend towards maple dominance of the regeneration layer as these stands recover from pulses of acute herbivory associated with high-severity winters and the press of chronically high herbivory that precedes them.

Abstract Managing northern hardwood forests using high-frequency, low-intensity regimes, such as single-tree selection, favors shade-tolerant species and can reduce tree species diversity. Management decisions among family forest owners (FFO) can collectively affect species and structural diversity within northern hardwood forests at regional scales. We surveyed FFOs in the Western Upper Peninsula of Michigan to understand likely future use of three silvicultural treatments—single-tree selection, shelterwood, and clearcut. Our results indicate that FFOs were most likely to implement single-tree selection and least likely to implement clearcut within the next 10 years. According to logistic regression, prior use of a treatment and perceived financial benefits significantly increased the odds for likely use for all three treatments. Having received professional forestry assistance increased likely use of single-tree selection but decreased likely use of shelterwood. We discuss these results within the context of species diversity among northern hardwood forests throughout the region.

Riparian forests with oaks, ashes and elms, now highly fragmented and rare in Europe, are considered hotspots for ecosystem services. However, their capacity to provide pollination seems to be quite low, although reports from in-situ research supporting this view are scarce. Our goal was therefore to thoroughly assess their pollination potential based on multifaceted field measurements. For this, we selected six test sites with well-developed riparian hardwood forests, located in the agricultural landscape along the middle Vistula River in Poland. We used seven indicators relating to habitat suitability (nesting sites and floral resources) and pollinator abundance (bumblebees and other Apoidea) and propose a threshold value (AdjMax) based on value distribution and Hampel’s test to indicate the level of pollination potential for this type of riparian forest. The obtained AdjMax for bumblebee density was 500 ind. ha−1, for Apoidea abundance—0.42 ind. day−1, while for nectar resources—200 kg ha−1. We demonstrate that the investigated small patches of the riparian hardwood forest have a higher pollination potential than reported earlier for riparian and other broadleaved temperate forests, but the indicators were inconsistent. As forest islands in the agricultural landscape, riparian hardwood forests play an important role in maintaining the diversity and abundance of wild pollinators, especially in early spring when there is still no food base available elsewhere.

Field Stations

Morphologic and mass measurements were taken on 24 complete white-tailed deer (Odocoileus virginianus) carcasses of varying ages and both sexes in southern Quebec. Each carcass was divided into three parts (skin, viscera, rest) to determine water, protein, fat, and ash content by chemical analyses. Fat content of carcasses varied between 0.8 and 17.4%. Multiple linear regression models were selected to predict carcass composition from morphologic and mass measurements. Two situations were considered: measurements taken at the laboratory on whole animals and measurements taken at field stations on eviscerated carcasses provided by hunters. All selected models can be applied to any deer without taking into account age or sex; they include 1 – 4 independent variables. For whole animals, adjusted R2 of models varied between 0.99 (water) and 0.89 (ash); models developed for field stations were less precise, the lowest R2 values being 0.82 and 0.73 for ash and fat, respectively. These models can be useful for research and management purposes.
