"text": "Bergmann's rule, an eco-evolutionary generalization predicting that endothermic animals will be larger in cold climates and smaller in warm climates, gives an explanation for the evolution of body size variation among similar groups of organisms (Bergmann, 1847;Salewski and Watt, 2017), which has been deployed to understand various aspects of ecology, such as predator-prey relationships (e.g., Mcnab, 1971). Although this hypothesis has been tested across different taxa, such as mammals (Clauss et al., 2013), birds (Ashton, 2002), and insects (Scriven et al., 2016), there is still an ongoing debate on its suitability for intra-and inter-specific studies (see Shelomi, 2012;Clauss et al., 2013). Simultaneous investigation of intra-and inter-specific variations in body size will enhance our understanding of the generalization of the Bergmann's rule. This is particularly important if such studies are conducted on little known species and regions such as Afrotropical regions."

"text": "The contrasting results obtained from the investigation of Bergmann's hypothesis suggest influence of other confounding factors, such as microclimates along latitudinal and altitudinal gradients (e.g., Shelomi, 2012;Bhusal et al., 2019). With the global climate change affecting all life forms on earth (Crozier et al., 2008;Şekercioĝlu et al., 2012), understanding species adaptation is important from an applied perspective. Species would need to adjust their physiology and behavior in order to cope with changing climatic conditions (Tieleman and Williams, 2000). Such studies are seldom reported from tropical areas, particularly Africa, which holds huge biodiversity, but projected to be adversely affected by global warming in the nearest future (Midgley and Bond, 2015;Sintayehu, 2018)."

"text": "Due to their relative ease of trapping, birds are an important model for physiological studies. Here, we tested the Bergmann's rule within and across 30 avian species along vegetation and altitudinal differences in Nigeria, West Africa. While several studies have supported the Bergmann's rule, demonstrating that average body size within a species tends to increase toward cooler and higher latitudes (Ashton, 2002), we chose to test this rule along an altitudinal gradient because the north-south temperature gradient at the same elevation in Nigeria is small (an average difference of 7 • C) and a previous study has already demonstrated a lack of relationship between latitude and body size in Nigeria (Nwaogu et al., 2018). We hypothesized a larger avian body size at high altitudes compared to lower altitudes and that the magnitude of size difference between lowland and montane populations will differ with respect to vegetation type (savanna vs. rainforest) and species."

"text": "For species with at least 10 records at both lowland and montane areas, we used the R package (R Core Team, 2016) to perform a principal component analysis (PCA) (Cozzolino et al., 2019) based on a correlation matrix using body mass and wing length. Both wing length and body mass are an indication of body size and have been consistently recorded at all ringing data but rather than analyze them separately, by using PCA, we can combine these two response variables into a single component to produce an index of body size. This procedure produces principal component scores for each individual; negative and low vales of scores indicate individuals with shorter wings and lighter body mass (i.e., smaller body sized individuals) while positive and higher values indicate larger body sized individuals. Because principal component scores had a Gaussian distribution, we used a general linear model to investigate if body size was affected by altitude (m), average monthly temperature ( • C), total monthly rainfall (mm), using latitude as weighted variable. We used latitude as a weighting factor rather than an explanatory variable because a previous study testing the Bergmann's Rule along latitudinal gradient indicated that latitude had a slight but non-statistically significant effect on body size of birds in Nigeria (Nwaogu et al., 2018). By doing this, we also avoided over-parameterization of models while still adjusting for possible, if only slight, effect of latitude. To also avoided over-parameterization of models, the northern and southern sites were analyzed separately. Because temperature and rainfall were correlated, we analyzed their effect on body size in two separate models in order to avoid effects multicollinearity."

The results of the principal component showed high and A plot of PC1 against PC2 and the general linear model with site as predictor indicated that for the southern zone, montane populations were on average significantly heavier than lowland populations, but with lowland species having a comparable longer wing length (Figure 2 and Table 1). Of the six species analyzed, only the Olive Sunbird Cyanomitra olivacea had a higher body size in the lowland population (Supplementary Table 1). However, since PCA 2 is the component of wing length and since lowland species have more positive scores along PCA 2 axis (Figure 2), it means that even though they are smaller than their montane counterparts, their wing length are comparatively longer. The GLM indicated that temperature was a significant predictor of body size, with body size and temperature having a negative relationship, The three-way interaction of location, species, and temperature was significant, indicating that differences in size between species was due to temperature variations between location (Table 1, Model a). Rainfall was not a significant predictor of body size and the three-way interaction between location, species, and rainfall was not significant either (Table 1, Model b), therefore, rainfall cannot explain the differences in body size between lowland and montane sites in the southern zone."

Of the 24 species considered in the study, populations of 17 species were heavier in montane areas while populations of seven species were heavier in lowland areas (Supplementary Table 1). A general linear model showed that both temperature and rainfall were significant predictors of body size (Table 2, Models a and b) with temperature showing a negative effect on body size. The three-way interaction of location, species, and temperature was significant indicating that temperature was responsible for the difference in body size of species at the different elevations. Although there was a significant effect of rainfall on the body sizes of species but the three-way interaction of location, species, and rainfall was not significant (Table 2, Model b). This is supported by weather data which shows that temperatures were lower at higher altitudes compared to lower (Figure 4A) latitudes whereas rainfall pattern did not follow and altitudinal trend (Figure 4B)."

Nwaogu et al., 2018), our findings shed more light on the importance of microclimates while testing the Bergmann's rule along altitudinal gradients. To our understanding, this is the first study to simultaneously consider the interplay of these factors in the afrotropical context."

In the present study, montane populations were significantly heavier than lowland populations in the Guinea forest region. However, in the savanna region, there was extensive overlap in body sizes between montane and lowland populations. This pattern suggests the influence of other microclimates and macroclimate factors."

Indices of body sizes indicated that populations in the southern zone were larger than the northern zone; body size on the Obudu Plateau were significantly larger than birds on the Jos Plateau (difference = 1.29, CI = 0.06-1.91, p < 0.001, Figure 4) and birds from IITA were also significantly larger than those of Yankari (difference = 0.36, CI = 0.12-0.59, p < 0.001; Figure 5)."

"text": "For instance, we found that temperature significantly influenced body size in both rainforest and savanna regions, whereas, rainfall only had a significant impact on savanna species populations in the north. This is hardly surprising. Unlike temperature, the duration and volume of rainfall in Nigeria is significantly higher in the southern rainforests in comparison with the northern savanna (Anyadike, 1993;Obot et al., 2010). Shorter rainfall duration and intensity in the north would result in shorter periods of food availability, thus resulting in a lower body size index. In highly variable environments when food availability is limited or unpredictable, a larger body size is a disadvantage because larger bodied individuals require high energy intake in order to meet their energy requirement (Yom-Tov and Geffen, 2006). This premise is supported by our results which show that in the same species, the northern populations were smaller than the southern populations for both lowland and montane regions. In addition, it is likely that the temperature difference between the montane and the lowland habitat in the savanna region was not wide enough to impact on body size difference in the studied populations (Figure 4). Although there was a wide altitudinal gradient between the Jos Plateau and the lowland Yankari, the temperature difference between these sites was less than 1 • C."

"text": "Our study has not only shown the applicability of the Bergmann's rule across afrotropical bird species, but also of its potential in understanding the impacts of climate change, which is important from a conservation standpoint. Although we attempted to fill knowledge gaps, our findings have exposed many others, which should provoke further studies. Since Africa supports a host of ecoregions and microclimates along latitudinal and altitudinal gradients (Olson et al., 2001), we would benefit more if further studies are conducted in understudied regions and species, particularly those that are sexually dimorphic (Blanckenhorn et al., 2006;Scriven et al., 2016). This study has also highlighted the need to study the potential impacts of climate change on avian species due to increasing temperature and erratic rains particularly its effect on the physiological state of organisms (Brown, 1996). Body condition, for instance, is known to influence survival and breeding in many species (Kitaysky et al., 1999;Souchay et al., 2013)."

] | 78ad0571-e2b3-48f8-b070-05104f6cb7e8 | The Bergmann's rule predicts that in endotherms, body sizes will differ with respect to thermal gradients. Larger bodied individuals will inhabit colder environments while in warmer environments, individuals will be smaller-bodied. This hypothesis has been proved and disproved many times due to inconsistencies in body size differences along latitudinal gradients. We tested this hypothesis in 30 Afrotropical resident bird species inhabiting two vegetation types at different latitudes (southern guinea forests and northern savanna) and at different altitudes in Nigeria, West Africa. Using principal component analyses of body mass and wing length, the first principal component, the component of size, indicated that individuals in montane areas were larger than lowland populations in southern guinea forests. However, in the northern guinea savanna, there was no significant difference in body sizes between lowland and montane populations. General linear models show that body size increases as temperature decreases. In species found in both southern guinea forests and northern savanna (i.e., African Thrush Turdus pelios and Snowy-crowned Robin Chat Cossypha niveicapilla), variations in body sizes were significantly dependent on sites. Our study indicates that other macroscale factors such as vegetation and rainfall patterns might modulate conformity to Bergmann's rule in Afrotropical environments. |

The model therefore chose the purchase of commercial concentrate during the dry season in cows producing 1,350 kg and 1,500 kg per lactation, but jaragua grass cannot support a production of 2,000 kg per lactation without there being additional protein and energy supplements throughout the year.

Pucallpa has 41% of the herd in milk while this figure is close to 60% in Costa Rica and Nicaragua (Table 2). To offset this effect, the percentage of milking cows in the Pucalpa herd must be increased throughout the year to a minimum of 53%, or the stocking rate must be increased from the current 0.9 AU/ha to 1.3 AU/ha by introducing more animals. Under current conditions, degraded native pastures cannot support these high stocking rates and the forage alternatives tested could become viable."

Even if the investment in these forage alternatives was economically superior, the real interest rate in Peru is so high that farmers would not have the option of intensifying production. They would not be able to pay the 34% real interest in any scenario (not even if cow productivity were 2,000 kg per lactation or terms of payment were over 10 years).

Calf weight gain was similar, whether with Stylosanthes or with the traditional system, but milk production (in the bucket) increased by 1 liter per cow (22%) per day. This technology may be readily accepted by small-scale farmers in the short term because it increases their incomes from milk sales without affecting calf development and using relatively small areas of Stylosanthes-based pastures. Consequently, this forage alternative is perhaps the only one in Pucallpa to have good possibilities of being adopted. "

] | 52f84eb0-81c7-4a63-b7df-47d2eb6935b9 | The objective was to perform an ex-ante economic evaluation of new, legume-based forage alternatives available to farmers in Latin American tropical lowlands. These alternatives included grasses of the Brachiaria genus and the legumes Stylosanthes guianensis, Cratylia argentea, and Arachis pintoi. Case studies, involving farmers participating in the CIAT-led Tropileche Consortia convened by ILRI, were conducted in the forest margins of Pucallpa (Peru) and in the hillsides of the dry tropics of Esparza (Costa Rica) and Esquipulas (Nicaragua). A linear programming farm model developed by CIAT to maximize income was used for this analysis. Animal management parameters were based on farm averages at each reference site evaluated so that they represented current management conditions. Similarly, the model incorporated the prices of inputs and products typical of each country. A constant herd size was assumed for all alternatives evaluated. Production costs per kilogram of milk were estimated as the maximum expression of competitiveness, using three cow productivity parameters: the current average production per lactation (800 kg in Peru, 1,000 kg in Nicaragua, and 1,350 kg in Costa Rica); and two postulated parameters: 1,500 kg/lactation and 2,000 kg/lactation. For all forage options, key factors analyzed were (1) milk production costs resulting from implementing each forage alternative; (2) the investment required to establish each option, assuming the same number of milking cows and herd fertility; (3) the feasibility of obtaining credit with a local bank to invest in a forage alternative; and (4) the percentage of pasture area on the farm freed for other uses as a result of establishing one of the forage alternatives.Results indicated that the forage alternatives evaluated significantly improved the competitiveness of dual purpose farms in the hillsides of Nicaragua and Costa Rica, reducing the cost of producing milk between 13% and 37% with increased stocking rates, releasing up to 36% of area allocated to pastures. However, under current commercial banking conditions (real interest rates of 13% in Costa Rica and 18% in Nicaragua with payback periods of 5 years), the implementation of the options evaluated were not financially viable except for the establishment of Cratyla with sugarcane for dry-season feeding and Stylosanthes for pre-weaned calves. For all options to be implemented with commercial credit, a longer payback period was needed (8-10 years) and lower real interest rates (5-10%). The case of the forest margins of Pucallpa, was different, as none of the forage options evaluated, except Stylosanthes for pre-weaned calves, improved the competitiveness of farms under current management and production conditions due to low milk yields per cow and low proportion of herd in milk, which increased depreciation cost/cow to levels which were not viable. In addition, Pucallpa has an excess supply of forage biomass from a reduced herd inventory during the 80s and a limited fresh milk market which makes adoption of improved forages low attractive by farmers.peru holmann |

Europe, especially France and Switzerland, remains the main market for organic products from West Africa. Organic agriculture is mostly practised by small producers but the price premium and the importance of the European market may encourage large producers to use this type of practice. Competition coming mostly from countries from Latin America and the risk that the organic market becomes oversupplied may both decrease the price premium. However, this decrease might lead more and more consumers to prefer organic products to conventional products. SO 14001 is designed to help the implementation of environmental management systems for organizations in both the private and public sectors. It was created by the International Organization for Standardization (ISO) which is an international network of national standard institutes working along with governments, industry and consumer representatives. While there are a number of other ISO standards that can be used as environmental management tools, only ISO 14001 can be used for certification.

Therefore, the effect largely depends on the commitment of the individual company. Also the ISO logo cannot be used on products.

EUREPGAP aims to increase consumers' confidence in food safety by developing \"good agricultural practices\" (GAP) which must be adopted by producers. It also aims to harmonize buyers' requirements for food hygiene and for maximum residue limits for pesticides. Unlike the other certification programmes, the focus of EUREPGAP is not on environmental or social issues but rather on food safety and traceability. However, the EUREPGAP standard also includes some requirements on the use of pesticides, workers safety and compliance with national labour regulations. Among all the EUREPGAP standards, the one on fruits and vegetables is the most advanced 2 . It should be borne in mind that EUREPGAP has not been established by the European Union. he EUREPGAP standard requires that producers establish a complete control and monitoring system. Products can then be registered and traced back to the specific farm unit where they were grown. EUREP rules are relatively flexible about field practices such as soil fumigation and fertilizer usage. There are strict regulations about pesticide storage and pesticide residue limits. In addition, it is important to document and justify how the product was produced, so detailed records must be kept about farm practices."

Aun cuando este fenómeno ha sido corregido en parte por cruzamientos y un mejor desarrollo de las novillas de primer servicio, se observa en rebaños 'con una adecuada eficiencia reproductiva que las vacas de primer parto tienen una efi~iencia reproductiva muy por debajO del promedio del rebaño (Plasse 1979).

"text": "La presentación periódica de épocas de insuficiencia en el aporte de alimentos es casi habitual en las regiones tropicales, como consecuencia de la pronunciada estacionalidad de ras pasturas. De esa situación deriva que los animales en crecimiento manifiesten un retardo en la .evoluciÓn de su conformación y aptitudes. En. las vaquillas se registra una demora de más de siete meses en la presentación de la pubertad y de alrededor de más de 10 meses en la obtención de la primera cria (Helman 1977). La sequía se convierte en estas condiciones en un modifi~ador preponderante de los sistemas de producción (Paladines y Leal 1978). En la sabana nativa, la baja carga animal que se emplea, es lo que permite el mantenimiento del equilibrio biológico. Los intentos de intensificación de la producción, con el solo 'aumento de la carga animal, tienen como consecuencia final la perturbación del balance ecológico y la disminución de la productividad, ya -inicialmente baja (Vilela '1977, Paladines y Leal 1978). La vegetación predominante en la sabana nativa y que es consumida por el ganado como forraje, está constituida por: Trachypogon vestitus, Heptochoritium lanatus, Paspalum pectenatum, Andropogon semiberbis, Axenopus pulcher, Panicum versfcolor, etc.; los cuales ofrecen allá una disponibilidad de forrajes (Paladines 1978). No es posible afirmar que la~ diferencias en ganancia de peso se deban a la di•sponibil idad de forrajes. En este tipo de praderas la quema juega un papel importante. siendo costumbre quemar las praderas durante la época seca para conseguir un rebrote tierno, en esta forma se consigue aumentar el crecimiento de los animales hasta en 250% (Paladines y leal 1978)."

Las novillas de carga media alcanzaron dicho peso tres meses después, mientras que las de carga alta llegaron al final del experimento con solo 219 kg en promedia. Esto fue debido principalmente al efecto de la carga sobre las disponibilidad de forraje; aún que la calidad fuera buena, la baja disponibilidad de forraje en la carga alta afecta tremendamente el crecimiento y consecuentemente en el comportamiento reproductivo de dichas novillas. la edad a la cual se presentó el primer celo estuvo relacionada en este trabajo con el peso vivo. .. ,"

A Curated Research Corpus for Agricultural Advisory AI Applications
This dataset represents a comprehensive collection of 45,232 agricultural research publications from CGIAR, specifically processed and structured for Large Language Model (LLM) applications in agricultural advisory services. This dataset bridges the gap between advanced agricultural research and field-level advisory needs, drawing from CGIAR's extensive scientific knowledge base that has been used by both public and private extension services. Each document has been systematically processed using GROBID to extract structured content while preserving critical scientific context, metadata, and domain-specific agricultural knowledge. The corpus covers diverse agricultural topics including crop management, pest control, climate adaptation, and farming systems, with particular emphasis on small-scale producer contexts in low and middle-income countries. This machine-readable dataset is specifically curated to enhance the accuracy and contextual relevance of AI-generated agricultural advisories through Retrieval-Augmented Generation (RAG) frameworks, ensuring that advanced agricultural science can effectively benefit those at the heart of agriculture.
Data Sources and RAG Pipeline
The dataset is sourced from GARDIAN, a comprehensive hub for agri-food data and publications. Utilizing its robust API, the GAIA-CIGI pipeline has systematically discovered and gathered all open-access reports and publications from the various CGIAR centers. Each document has been converted into a structured, machine-readable format using GROBID, a specialized tool for extracting the structure of scientific publications. A complete description of the system architecture can be found here
